Explanation / Answer

public class numPtr {
    public static void main( String arg[]){
        int c=2,d=0;
        for(int i=1;i<=10;i++){

            for(int j=1;j<=i;j++){
                System.out.print("*");
            }
            System.out.println();
        }
        for(int i=1;i<=10;i++){
            for(int j=10;j>=i;j--){
                System.out.print("*");
            }
            System.out.println();
}

        while(c>0){
        if(d==0){
            for(int i=1,r=10;i<=10;i++,r--){
            for(int j=1;j<=r;j++){
                System.out.print("*");
            }
            System.out.println();        }
            d++;
       } else{
            for(int i=1;i<=10;i++){
            for(int j=1;j<=i;j++){
                System.out.print("*");            }
            System.out.println();
        }
        }
        c--;
