Java Interview Questions for Freshers

Dear readers, these Java Interview Questions have been designed especially to get you
acquainted with the nature of questions you may encounter during your interview for the subject
of Java Programming Language. As per my experience, good interviewers hardly planned to ask
any particular question during your interview, normally questions start with some basic concept of
the subject and later they continue based on further discussion and what you answer

These are some samples what is in the file:-

Q: What is JAR file?
A: JAR files is Java Archive fles and it aggregates many files into one. It holds Java classes in a
library. JAR files are built on ZIP file format and have .jar file extension.

Q: What is a WAR file?
A: This is Web Archive File and used to store XML, java classes, and JavaServer pages. which is
used to distribute a collection of JavaServer Pages, Java Servlets, Java classes, XML files, static Web
pages etc.

Q: What is NullPointerException?
A: A NullPointerException is thrown when calling the instance method of a null object, accessing or
modifying the field of a null object etc.

Q: What are the ways in which a thread can enter the waiting state?
A: A thread can enter the waiting state by invoking its sleep() method, by blocking on IO, by
unsuccessfully attempting to acquire an object's lock, or by invoking an object's wait() method. It
can also enter the waiting state by invoking its (deprecated) suspend() method.

Benefits of VPN Include
Security - VPNs provide the highest level of security using advanced encryption and authentication protocols that protect data from unauthorized access. When you create a private virtual tunnel between your computer and ours, and surf the internet from there, your VPN account is giving you a layer of security you did not have before.

Anonymous Surfing - Our service will make anonymous and secure your Internet connection, creating an encrypted tunnel between you and our servers. This will assign a new ip address to your computer, in this case your online activity is anonymous and prevents harassment caused by people tracking you by your IP address.

Wi–Fi® Security for a Wireless World™ - when you use public Wi–Fi® hotspots, all the information you send to and receive from the Internet is sent over the air in the clear. Wi–Fi® is a radio, broadcasting everything to anyone who bothers to listen. Web pages, emails and passwords, instant message traffic, everything that’s not encrypted is readable by anyone in the area.

PD-Proxy uses industry–standard Virtual Private Networking (VPN) technology to create a secure tunnel between your laptop and the PD-Proxy servers. When you connect to PD-Proxy, all your Internet traffic goes through this encrypted tunnel, preventing users nearby from intercepting your information.

Stretching higher than the Eiffel Tower, the Viaduc de Millau Bridge is a marvel of art and architecture that caught the eye of even flamboyant French President Jacques Chirac. Stretching across southern France's Tarn River Gorge, it is 1.6 miles (2.6 kilometers) long and soaring to 1,132 feet (343 meters) at its highest point, it is the tallest bridge in the world. Built by the firm that also built the Eiffel Tower, its spectacular presence bowls over one and all!
8. Bird’s Nest

The Bird’s Nest in the heart of Beijing needs little introduction to anyone, and it is one structure that has now become synonymous with the Olympic Games. Apart from its grand, yet unique design, the stadium is the world’s largest steel structure. No other man-made structure used up as much steel as the Olympic Stadium, with its intricate yet hypnotic design. That surely sets it apart in terms of being a one of a kind venue in the sporting world.
9. Burj-Al-Arab Hotel

By now almost everyone knows about the Burj-Al-Arab, and if you have not heard of it or seen its picture till now, then welcome back to earth. The hotel stands at a height of 321 meters and is the tallest operational hotel in the world. While the Rosa Tower is set to soon take away that crown, it still will not diminish the unique aura of the Burj, with its unique shape and its own artificial island. This is one hotel where you can live it up in a grand style!
10. Kingda Ka Roller Coaster

At a height of 456 feet, the Kingda Ka Roller Coaster is the tallest fun ride in the world. Located in the Six Flags Theme Park in New Jersey, the ride will take you into a different world and even before you know it, you will be plunging back towards earth at a speed of 128 mph. This heart-stopping and mind-numbing ride is not just the tallest in the world but also the most exhilarating. This is a modern marvel that is just for fun and adrenaline, and that makes it our personal favorite!
11. Rungnado May Day Stadium

may day stadium largest capacity AQX26 7071
Located in Pyongyang, North Korea, the May Day stadium is the largest in the world and has seen some pretty big crowds. The May Day stadium has 150,000 seats and a total floor space of more than 207,000 square meters. The inner stadium floor area covers 25,000 square meters, including 14,000 square meters of which its athletic field is artificially made and 8,300 square meters of lawn. Vertical axis of stadium is 450 meters and horizontal axis 350 meters. Those are just a few numbers from this humongous stage for sporting extravaganza!
12. Akashi Kaikyo Suspension Bridge

The Akashi Kaikyo Suspension Bridge is the longest suspension bridge in the world and is a spectacular visual delight. It apparently took 2 million workers 10 years to construct the bridge, 181,000 tons of steel and 1.4 million cubic meters of concrete. The four-mile bridge links the island of Awaji and the mainland city of Kobe. This is probably one man-made marvel that even the Japanese are proud about and look at in awe!
13. Lake Mead

Lake Mead is one of my own personal favorites not just because it is such a spectacular human creation among nature’s brilliant creations, but it also brings in the aura of the Hoover Dam into the list. When it was completed, the Hoover Dam was the largest concrete structure in the world, and also the largest power-producing entity. With time all that might have gone, but the artificial lake it creates among the gorgeous Grand Canyons—Lake Mead—is still the world’s largest man-made reservoir. Simply spectacular!
14. Project Genesis

When finished in 2009, Royal Caribbean's Project Genesis luxury cruise ship will be the largest cruise ship the world has ever known. This modern-day luxury-on-ocean will end up costing a cool $1.24 billion to make. It will measure 1,180 feet long and carry 5,400 passengers. When ready, the ship would have a central park, luxury hotels, restaurants, public spaces, picnic spots and bars. Yes, it is like a little city of its own!
15. Hangzhou Bay Bridge

largest road bridge Af5SZ 7071
There is something about bridges that we just cannot get enough of. It is just the scientific knowledge and the engineering skill involved in building them that makes them stand out as technical pieces of art. The Hangzhou Bay Bridge is the longest road bridge in the world and another Chinese marvel that made it to our list. The £840 million Bridge, measuring 36km, spans Hangzhou Bay to link China’s financial hub and the port city of Ningbo to the south. The fact that it is anchored in waters that are 60 meters deep in places and yet is so solid and spectacular makes it a feat of accomplishment indeed!
16. Channel Tunnel

eurotunnel iOBes 7071
The Channel Tunnel, more popularly known as the Eurotunnel, is the longest under-sea rail tunnel in the world in terms of length of the tunnel under the sea. Connecting England and France, it starts out at Kent in England and finishes at Coquelles near Calais in northern France. Creating a bridge over water is hard enough but to plow under the sea to create a rail tunnel! This is one ride that you will never forget.
17. Singapore Flyer

largest ferry wheel singapore vKTIX 7071
These big giant wheels that go round and round giving you a spectacular view of the city are so cool, and the one in London is obviously pretty famous. But there is plenty of hard work and engineering skill behind the apparent simplicity. The Singapore Flyer is the world’s largest Ferris wheel and reaches 42 stories high, it comprises of a 150-metre high wheel built over a three-story terminal building, thus giving it a total height of 165 meters. It not only gives you a view of Singapore in totality but parts of Malaysia and Indonesia as well... Awesome!
18. Pan STARRS-1

Built at Manoa’s Institute for Astronomy in Honolulu at the University of Hawaii, the largest digital camera has been installed on the Pan STARRS-1 telescope on Haleskala, Maui. This digital wonder along with the telescope will form one of the most powerful observatories on the planet and will monitor the cosmos constantly.
19. MareNostrum

super computer qy3Ix 7071

It is not often that science and religion get along well, and that makes the MareNostrum all the more special. MareNostrum is the most powerful supercomputer in Europe and while Europe does not cover the world, it is the only one where you will find a church. The supercomputer consists of 2560 JS21 blade computing nodes, each with 2 dual-core IBM 64-bit PowerPC 970MP processors running at 2.3 GHz for 10240 CPUs. All this in a chapel, and the ironic part: it is used for human genome research!
20. San Alfonso Del Mar
san alfonso del mar GMXsR 7071
san alfonso del mar GMXsR 7071
After taking a trip across the planet in search of the mind-boggling modern technological wonders, it is better everyone takes a cool dip on our final spot, and that is exactly why we reserved this one final spot for San Alfonso Del Mar in Chile. This amazing resort in the beautiful South American country sports the world’s largest swimming pool, and when I say large, I mean it. The San Alfonso pool is 1km in length and contains an incredible 250,000 cubic meters of water. The technology used to create the crystal clear water that is transparent to a depth of 35 meters is the real technological aspect of this pool, and an exclusive secret for now. The pool, spread over 8 hectares, is surely good enough for all those who came along on this fabulous journey!
That is the end of the journey, I’m afraid. Hope you all had as much fun and clicked on as many amazing images of these breathtaking human creations as I did. Now that you all cooled off at the San Alfonso Del Mar, just wipe yourself dry and head back home with the memories... Or you can enjoy the pool a bit longer. Adios!
