Java Number pattern 20 program with Explanation ~ Tutorialsweb

Write "Java" program to print below Number Pattern 20:

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

· Java For loop
· Java programming operators.

Java Number pattern 20 program using For loop:

class numberPattern20

public static void main(String[] ags)

{
  int i,j;
  for(i=1;i<=5;i++)
  {
    for(j=1;j<=i;j++)
    {
      System.out.print(j%2);
    }

    System.out.println();

Output:

Explanation:

The first two integers "i", "j" 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 " j%2" value. Print up to second for loop condition becomes False.
when the value of "i" becomes "6" the program terminates.
