Java Number pattern 1 program using For loop

Write "Java"  program to print below Number pattern 1:

To understand this example, you should have knowledge of the following topics:
·   Java programming operators.

Java Number pattern program using For loop:
class numberPattern1
public static void main(String[] args) 
 int i, j;
 for(i = 5; i >= 1; i--)
   for(j = 1; j <= i ;j++)
  • 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=1 is less than “i” where (i =5) the condition is true. So it's print the value of “J”. And the value of “j” increments after printing value. It prints the value of J up to “j = 5” when becomes 6 it comes out the loop and increment value i = 2 and same process repeats.
  • Last where “i” value becomes “0” the first for loop condition becomes false and the program terminates.
