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

· Java if Else

· Java For loop
· Java programming operators.

Java Number pattern 13 program using For loop:

class numberPattern13

public static void main(String[] ags)

    int i, j,k;

    for(i=5;i>=1;i--)

        if(i%2==1) k=1;

        else k=i;

        for(j=1;j<=i;j++)

            System.out.print(k);

            if(i%2==1) k++;

            else k--;

        System.out.println();

Output:

Explanation:

The first three integers "i", "j" and "k" are declared of type int.
Then in the First for loop “i” value is initialized with a value 5.
Now “i” value is checked with the condition i >= 1 that is (5 >= 1). So the condition is True.
Now the loop checks the if condition if the condition is True then the loop enters into second for loop.
Now the loop enters into the second for loop and checks the condition j <= i. Where "j = 1". and print the value of "k".
And check the if condition and continues up to program termination.
