Java programming language is very vast programming language,even I must say each and every programming language is very vast. Understanding Java programming language and applying its concept needs the knowledge and skills of Java programming language. I have gone through various important questions during my ride to SCJP. So I have prepared a list of such important questions of Java programming language which will help you not only in understanding the topic but also If you are preparing for SCJP they will be helpful.

Try to answer these questions on your own but if you cannot recall the concept go refer book,any core Java book will do.

Important Core Java Questions :-

1.How many access modifiers a class can use and which are they?

2.What are the Instance variables?

3.What are local variables?

4.What is the default access modifier and how it is different from protected access modifier?

5.Can you ever mark a class as final?

6.Is it true that we can use abstract and final both on same time and same Java entity?

7.What is the IS-A and HAS-A relationship in Java?
