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 for
loop. 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 0
, 1
, 2
, 3
, 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 100
, 100
is less than 100
, which is false. At that time, it terminates the loop and comes out of it. We...
