Java Number pattern 19 program with Explanation ~ Tutorialsweb

Write "Java" program to print below Number Pattern 19:

To understand this example, you should have knowledge of the following topics:

· Java For loop
· Java programming operators.

Java Number pattern 19 programs using For loop:

class numberPattern19

public static void main(String[] ags)

   int i,j,k;
  k=1;
  for(i=1;i<5;i++)
  {
    for(j=1;j<=i;j++)
    {
      System.out.print(k++);
    }
    System.out.println();

Output:

Explanation:

The first three integers "i", "j" and "k" are declared of type int.
Then in the First for loop “i” value is initialized with a value 1.
Now “i” value is checked with the condition i < 5 that is (1 < 5). So the condition is True.
Now the loop enters into the second for loop and checks the condition j <= i. Where "j = 1". and the condition is True.
Now prints the k value by condition "k++". Print up to second for loop condition becomes False.
when the value of "i" becomes "6" the program terminates.
