Java program to print the following given pattern

Pattern:

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
10 20 30 40 50 60 70 80 90 100

In this example, we will see a java program in which we will try to print the above given pattern.

Algorithm:

Step 1: Start.
Step 2: Set lines =10.
Step 3: Define i,j.
Step 4: Set i=1.
Step 5: Repeat step 6 to step 10 until i<=lines.
Step 6: Set j=1.
Step 7: Repeat step 8 until j<= i.
Step 8: Print i*j and Set j = j + 1.
Step 9: Print a new line.
Step 10: Set i = i + 1.
Step 11: End.

Program:


public class Main
{  
public static void main(String[] args)
{  
	int lines=10;  
	int i=1;  
	int j;  
	for(i=1;i<=lines;i++)
	{
		// this loop is used to print the lines  
		for(j=1;j<=i;j++)
		{
		// this loop is used to print lines  
		System.out.print(i*j+" ");  
		}  
		System.out.println("");  
		}  
	}  
}

Output:
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
10 20 30 40 50 60 70 80 90 100
