if…else Statement

The if...else statement in Java provides a way to execute different blocks of code based on the evaluation of a boolean expression. If the boolean expression in the if statement is true, the code inside the if block is executed. If the expression is false, the code inside the else block is executed.

Example:

public class IfElseStatementExample {
    public static void main(String[] args) {
        int x = 10;

        // If-else statement
        if (x > 5) {
            System.out.println("x is greater than 5");
        } else {
            System.out.println("x is 5 or less");
        }

        // Another example
        int y = 7;
        if (y % 2 == 0) {
            System.out.println("y is an even number");
        } else {
            System.out.println("y is an odd number");
        }
    }
}

In this example:

• The first if...else statement checks if x is greater than 5 and prints a message accordingly.
• The second if...else statement checks if y is an even or odd number based on the remainder when divided by 2.

You can have multiple else if blocks to check additional conditions. The if...else statement allows you to handle scenarios where there are two possible outcomes based on the evaluation of a condition. The code inside the else block is executed only if the condition in the if statement is false.
