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:

Syntax:
if(test_expression)
{
    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.
