Java Number pattern 3 program using For loop:
class numberPattern1
{
public static void main(String[] args) 
{
 int i, j;
for(i = 5; i >= 1; i--)
 {
  for(j = i; j >= 1; j--)
   {
     System.out.print(j);
    }
      System.out.println();
  }
}
}
Output:
54321
4321
321
21

Explanation:
  • First two integers "i" and "j" are declared of type int.
  • Then in the First for loop “i” value is initialized with value 5.
  • Now “i” value is checked with the condition i >= 1 that is (5 >=1). So the condition is True.
  • Now the loop enters into second for loop and checks the condition j >= i.
  • So the value of j=5 is greater than “1” where (j =5) the condition is true. So it's print the value of “J”. And the value of “j” decrements after printing value. It prints the value of J up to “j = 1” when becomes 0 it comes out the loop and increment value i = 4 and the same process repeats.
  • Last where “i” value becomes “0” the first for loop condition becomes false and the program terminates.
