The for loop


Let's see how the for loop works. The for loop is one of the most commonly used loops in Java programs, and it it is very important to understand how it works internally. So, let's say we want to print the numbers from 1 to 100 using the forloop. For the syntax to execute the numbers from 1 to 100 in a sequence and to write that in a for loop, we will simply write:

// 1 to 100

/*  for(initialization;condition;increment)
       {
       } */
    for (int i=0;i<100;i++)
    {
        system.out.println(i);
        }
}

Since we want to print 0123, we use i++. This means for every loop, it increments only by  1. And while looping, each time, it also checks whether the preceding condition is satisfied. So, if 1 is less than 100, it goes inside; if 2 is less than 100, it goes inside. Until this condition is satisfied, it will keep on looping. When the value of i reaches 100100 is less than 100, which is false. At that time, it terminates the loop and comes out of it. We...
