Answer 1

for(int aj =5;aj>=1;aj--){

            for (int a1 = 0; a1 < aj; a1++) {
                System.out.print(" ");
            }
                    for(int a2 = 5;a2>=aj;a2--) {
                        System.out.print("$");
                    }
                for(int a2 = 5;a2>aj;a2--) {
                    System.out.print("$");
                }
            System.out.println();
