Before we learn the while and do...while loops, we will discuss the if condition in this section. In a Java program, when the if conditional statement is used, the statement in the if block is executed only if the condition is satisfied. Otherwise the statement from else block is run. Also this execution is just takes place once. In a for loop, a variable is initiated and the loop runs till the condition is satisfied.

However, in the if case, it will not keep on looping. It will just go inside the loop once the if condition is satisfied; otherwise, it will go into the else block. So, control will execute the statements present in this else block, as shown in the following screenshot: 

Output of the if...else condition as per the code

But all this happens only once, unlike the for loop, where a condition is satisfied until it goes back and executes.

Let's take a look at the following example:

    if(5>2)
    {
        System.out.println("success");
    }
    else
    {
