What does this compiler error mean ' ' in java?

Answer 1

Simply, the error that your compiler catches is called compiler error.

Doesn't matter if you are in Eclipse, NetBeans or Intellij IDEA, all these IDE's are very smart. They can detect if you made any any mistakes in your program.

Common compiler errors are-

-When you try and access a variable that is out of scope

-When you forget to give a semicolon.

-When you will try to use a reserved keyword like - return.

-Any syntax error that your compiler might find suspicious, will cause compiler to throw an error.
