Write "Java" program to print below Number Pattern 4:
To understand this example, you should have knowledge of the following topics:
· Java programming operators.
Java Number pattern 4 programs using For loop:
class numberPattern4
{
public static
void main(String[] args)
{
int i, j;
for(i
=1;i<=5;i++)
{
for(j=5;j>=i;j--)
{
System.out.print(j);
}
System.out.println();
}
}
}
Output:
543215432543545
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 the 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 = 2 and the same process repeats.
- Last where the “i” value becomes “6” the first for loop condition becomes false and the program terminates.
