In this section, we will learn the while
loop in detail. First, create a new class. Now let us see how we can utilize this while
loop when programming our code. Let's say we want to print the numbers from 1 to 10, sequentially. How do we print this using the while
loop? The basic syntax of the while
loop is:
// While loop while(boolean) { }
And here, if the Boolean expression returns true
, only then will the control go inside this loop, whereas if the expression returns false
, then the control will not go inside the loop. That's the basic simple concept you have with the while
loop. Now let's say we want to bring in the numbers from 1 to 10. For this, we will write the following code:
//While loop //1 to 10 int i=0; while(i<10) { System.out.println(i); }
As you can see, in the preceding code example, we can see that that the given condition is true. So, it goes inside the loop and prints the value of i
. This loop keeps on executing until the expression evaluates...
