Getting confused with == and = in “if” statement

Question

I know that we cant use assignment operator in if statements in java as we use in any other few languages.

that is

            int a;

            i         


        

Answer 1

In java, you don't have implicit casting. So non-boolean values or not automatically transformed to booleans.

In the first case, the result of the statements is an int, which is non-boolean, which will not work. The last case, the result is boolean, which can be evaluated in an if-statement.
