Completing answer using recursion

Code: (Text FIle Also Included In End)

Output:

Code:

// Pattern Class
public class Pattern {

    // Main Method calling printPattern Method and Printing
    public static void main(String[] args) {
        /*
        * Here 1 tells that this is first turn of recurssion
        * and n is maximum number of recurssion required
         */
        printPattern(1, 10);
    }

    // Print Pattern Method
    private static void printPattern(int recurssionTurn, int n) {

        // Loop for Print *
        for (int i = 0; i < recurssionTurn; i++) {
            System.out.print("*");
        }
        System.out.println("");         // Break Line
        recurssionTurn++;              // Increasing Recurssing Turn
        if (recurssionTurn <= n) {        // If Recurssion has not reached target, call Again
            printPattern(recurssionTurn, n);
        }

    }
