Java Else Statement

Java else statement

Created By: chatGPT

In Java, the else statement is a fundamental control structure that allows you to execute a block of code when a specified condition is false. It is often used in conjunction with an if statement to create a branching logic in your code. This effectively enables decision-making in your applications, ensuring that the appropriate actions are taken based on the conditions evaluated.

if (condition) {
    // execute this code if condition is true
} else {
    // execute this code if condition is false
}

You can also utilize the else if statement to test additional conditions if the first if condition evaluates to false. This allows you to handle multiple scenarios without resorting to deeply nested if statements, which can make your code difficult to read and maintain.

if (condition1) {
    // execute this code if condition1 is true
} else if (condition2) {
    // execute this code if condition2 is true
} else {
    // execute this code if both conditions are false
}

Here’s an example that illustrates how the if, else if, and else statements can be structured in a Java program. In the following code, we evaluate a simple condition to determine whether a number is positive, negative, or zero. This showcases the basic use of if-else logic.

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

        if (number > 0) {
            System.out.println("The number is positive.");
        } else if (number < 0) {
            System.out.println("The number is negative.");
        } else {
            System.out.println("The number is zero.");
        }
    }
}
