Answer 1

Your inner for loop

for (int j = (rows + 1 - i) ; j  > 0 ; j-- ){
    System.out.print(j);
}

will always count down to 1, because it keeps going until j is zero. Also, the number that the current row starts on will depend on the current row, because you used i in your assignment to j. To get pattern 1 both of those things will have to change.
