For Loop
The for loop is a repetitive control structure that allows you to write an efficient loop that needs to be executed a specific number of times. The for loop is useful when you know the exact number of iterations required. Similar to the while loop, the for loop is also an entry-control loop where the given condition determines execution.
Syntax:
In Java, a for loop is implemented using three components. Below are the components of the for loop in Java:
-
Initialization: Contains the initial value statement(s) of the loop counter.
-
Boolean expression: Contains the condition that needs to be tested.
-
Body: Contains the statement(s) to be executed repeatedly until the given boolean expression becomes true, and also updates the loop counter.

Source Code:
public class ForLoop {
public static void main(String args[]) {
for(int x = 10; x < 20; x = x + 1) {
System.out.print("value of x : " + x );
System.out.print("\n");
}
}
}Result:
Source Code:
public class StarSingleLoop {
public static void main(String[] args) {
int n = 5; // Number of rows
for (int i = 1; i <= n * n; i++) {
System.out.print("* ");
if (i % n == 0) { // Break line after every 'n' stars
System.out.println();
}
}
}
