A loops statement allows us to execute a statement or group of statements
multiple times and following is the general form of a loop statement in most
of the programming languages . To gain a bit more control over the execution of a loop, we have another option. The for loop requires three different statements to operate. The first statement is called an initialization, the second is a condition, and the third is an operation.

Here is the flow of control in a for loop

For Loops

Following is an example code of the for loop in Java. In this example we displays the values between 10 to 20 using the for loop. Here int x=10 is the initialization x < 20 is the loop condition i.e. loop will be continue if the value is greater than 10 and less than 20, and x=x+1 is a increment. The print statements in the programs are the conditional code which is execute when the loop condition is true.

public class Test {
public static void main(String args[])
for(int x = 10; x < 20; x = x + 1) 
System.out.print("value of x : " + x );

This will produce the following result:

value of x : 10
value of x : 11
value of x : 12
value of x : 13
value of x : 14
value of x : 15
value of x : 16
value of x : 17
value of x : 18
value of x : 19
