Java Interview (Tips and Tricks to crack)

Hello Coders,
Do you love programming and want to become a Java Developer? Here are the some tips and tricks to crack the Java interview.

• Improve your logic by Basic Fundamentals
◦ How to do that?? Do the programs by using condition statements(if, else, else if, switch) and Loops (while, do..while, for).
◦ Try to do the same program in different way. For example. Find even no with ‘%’ and without ‘%’.Print factorial of a no without using loops.
◦ Try as many as numerical, star and alphabet Pattern. Don’t do trial and error by using IDE. Try it on paper. Dry run and then execute on machine. This is the best practice.
◦ Next concept is Array. Understand the array structure. How the values are Store. Array data structure is widely used.

• Second important concept is OOP pillars in Java i.e. Encapsulation, Abstraction, Inheritance, Polymorphism.
◦ In Encapsulation - Understand the concept of getters-setters and Nested Classes
◦ In Abstraction – Understand the concept of Abstract Class and Interface.
◦ In Inheritance – Understand the concept of Is-A and Has-A relationship.
◦ In Polymorphism – Understand the concept of Compile time polymorphism and Run time polymorphism. Understand the rules of Overloading and Overriding

• String – This is very important topic in interview point of view. Understand the String memory management, String methods, Do some programming without using String API. For example, Find the reverse of String (Input -I love India output – India love I).

• Exception Handling – In this topic important points are Exception propagation, difference between throw and throws, try with resource and the use of finally block.

• Multithreading - Important points of multithreading are life cycle of thread, ways of creating thread, use of Join, Synchronization, Inter-thread Communication, Deamon thread and Deadlock.

These are the some important topic in Java you need to study; with this you need some extra knowledge of JDBC i..e Java Database Connectivity. In interview interviewer may be ask for wring to the JDBC connectivity code; so be prepare with that. One suggestion is try to do one project in java by your own so your resume become strong and you will understand all the concepts.
Knowledge of Hibernate, Spring and Struts are not mandatory for freshers. But some basic knowledge is always helpful. So now start preparation.
