Develop programs to demonstrate use of Looping Statement 'for' in Java

Java Looping Statements: 

This article introduces the 'for' loop in Java, explaining its syntax and how it is used for iterative tasks. It provides examples and discusses common use cases.

Code:

public class ForLoopDemo {

    public static void main(String[] args) {

        for (int i = 1; i <= 5; i++) {

            System.out.println("Iteration " + i);

        }

    }

}

Output:

Iteration 1

Iteration 2

Iteration 3

Iteration 4

Iteration 5

Looping Through Arrays Using 'for' Loops in Java:

public class ArrayIterationDemo {

    public static void main(String[] args) {

        int[] numbers = {1, 2, 3, 4, 5};

        System.out.println("Iterating through a one-dimensional array:");

        for (int i = 0; i < numbers.length; i++) {

            System.out.println("Element at index " + i + ": " + numbers[i]);

        }

    }

}

Output: 

Iterating through a one-dimensional array:

Element at index 0: 1

Element at index 1: 2

Element at index 2: 3

Element at index 3: 4

Element at index 4: 5

Nested 'for' Loops for Patterns in Java

public class NestedForLoopsDemo {

    public static void main(String[] args) {

        int rows = 5;

        System.out.println("Pattern 1:");

        for (int i = 1; i <= rows; i++) {

            for (int j = 1; j <= i; j++) {

                System.out.print("* ");

            }

            System.out.println();

        }

    }

}

Output:

Pattern 1:
