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:
`12345`
`4321`
`123`
`21`
`1`
Explanation:
• 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 loop enters into second for loop.
• Now the loop enters into 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 terminate.
