Decision Control Structures

If statements in Java is used to control the program flow based on some condition, it's used to execute some statement code block if the expression evaluated to true; otherwise, it will get skipped. This statement is the simplest way to modify the control flow of the program.

The basic format of if statement is:


    statement 1;
    statement 2;

'Statement n' can be a statement or a set of statements, and if the test expression evaluated to true, the statement block will get executed, or it will get skipped.
