The if-then Statement

The if-then Statement

void applyBrakes() {
    // the "if" clause: bicycle must be moving
    if (isMoving){ 
        // the "then" clause: decrease current speed
        currentSpeed--;
    }
}

It tells your program to execute a certain section of code only if a particular test evaluates to true. If this test evaluates to false, control jumps to the end of the if-then statement.

The opening and closing braces are optional, provided that the "then" clause contains only one statement.
