Answer 1

For 3 years of experience in Java, prepare the following concepts for Java Interview:

Core java

• OOPS (specially differentiating abstraction & encapsulation)
• String (immutability), String Buffer, String Builder
• Threads (implementing ways, race around the condition, deadlock, etc.)
• Exception Handling
• Object class (hash code and equals methods)
• Comparator, comparable
• Interface, abstract class
• Collections (differences and when to use)
• Static class, static method, static block difference
• Final keyword - significance and use
• Heap area, stack area, string pool
• Singleton class and its implementation

Advanced Java

• Difference between JSP, Servlet
• Forward and redirect
• Life cycle of JSP and servlet
• JSP scriptlets, directives, declaration, expressions
