Java Number pattern 7 program using For loop:
class numberPattern7
{
public static void main(String[] ags)
{
int i, j;
for(i=1;i<=5;i++)
{
for(j=i;j>=1;j--)
{
System.out.print(j);
}
System.out.println();
}
}
}
Output:
1
21
321
4321
54321
Explanation:
- The 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 <= 5 that is (1 <= 5). So the condition is True.
- Now the loop enters into second for loop and checks the condition j >= 1. Where "j = 1".
- So the value of j=1 is equal to the value of "i" it prints the value if "j". Now the value of "j" is decremented to "0" the second for loop condition becomes a false loop comes out from the for a loop.
- Now the value of "i" is incremented to "2" and repeats the same process.
- Last where the “i” value becomes “6” the first for loop condition becomes false and the program terminates.
