Java Number pattern 15 program using For loop

Write "Java"  program to print below Number Pattern 15:


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

·  Java For loop
·   Java programming operators.

Java Number pattern 15 program using For loop:
class numberPattern15
{
public static void main(String[] ags)
{
    int i, j;
    for(i=1;i<=4;i++)
    {
       {
        for(j=i;j>=1;j--)
        {
            System.out.print(j%2);
        }
        System.out.println();
    }
  }
}
Output:
1
01
101
0101
Explanation:
  • First two integers "i", and "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 <= 4 that is (1 <= 4). So the condition is True.
  • Now the loop enters into second for loop and checks the condition j >= 1. Where "j = 1". and print the value of "j%2".
  • The value of "j" prints up to condition becomes False.
  • Now the value of "i" will be incremented by the condition "i = i++" and executes the loop.
  • when the value of "i"  becomes "5" the program terminates.
