Simple if/else statement

This is an example of how to use a simple if-else statement. The if-else statement is the most basic of all the control flow statements. It tells your program to execute a certain section of code only if a particular test evaluates to true. Using a simple if-else statement to check in a boolean variable implies that you should:

  • Create a new boolean variable set to false.
  • Use the boolean inside the if expression and execute some code if the expression inside the if statement is true.
  • Also incude some code to be executed in the else statement that will be executed when the expression in the if statement is false.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.basics;

public class SimpleIfElseStatementExample {

	public static void main(String[] args) {

		boolean b = false;

		if (b) {
			System.out.println("Variable value is true");
		}
		else {
			System.out.println("Variable value is NOT true");
		}

	}

}

Output:

Variable value is NOT true
