Java

The if statement is Java's conditional branch statement. It can be used to route program execution through two different paths. The if 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. The if statement is written with the if keyword, followed by a condition in parentheses, with the code to be executed in between curly brackets.

if( condition )
  {
    // body of the statements;
  }

//IF Statement in Java

import java.util.Scanner;

public class App {
    public static void main(String[] args) {
        int age;
        System.out.println("Enter Your Age : ");
        Scanner in = new Scanner(System.in);

        age = in.nextInt();

        if (age >= 18) {
            System.out.println("You are Eligible For Vote...");
        }
    }
}
