The for loop in Java is a control flow statement that allows code to be executed repeatedly based on a given condition. It is commonly used for iterating over a range of values, executing code multiple times, or traversing arrays and collections.
Syntax
for (initialization; condition; update) {// body of the loop}Copied!✕CopyExample: Printing Numbers from 1 to 5
public class Main {public static void main(String[] args) {for (int i = 1; i <= 5; i++) {System.out.println(i);}}}Copied!✕CopyOutput:
12345Copied!✕CopyExplanation:
Initialization: int i = 1; - This sets the starting point of the loop.
Condition: i <= 5; - The loop runs as long as this condition is true.
Update: i++ - This increments the loop variable after each iteration.
Example: Printing Even Numbers from 0 to 10
public class Main {public static void main(String[] args) {for (int i = 0; i <= 10; i += 2) {System.out.println(i);}}}Copied!✕CopyOutput:
