Number Right Angle Triangle Patterns

by

Number patterns are similar to ‘symbol’ patterns. The logic is similar to Right Angle Triangle Pattern. Let us see the code for number pattern.

public class Tech4Humans {

	public static void main(String[] args) {

		// length of triangle
		int size = 5;

		for (int i = 0; i < size; i++) {
			for (int j = 0; j <= i; j++) {
				System.out.print((j+1)+" ");
			}
			System.out.println();
		}

	}
}

Output

1 
1 2 
1 2 3 
1 2 3 4 
1 2 3 4 5
