The output has to be:
9*9= 81 9*8=72 9*7=63 9*6=54 9*5=45 9*4=36 9*3=27 9*2=18 9*1=9
8*8=64 8*7=56. . .
this will decrease until it reaches 1*1=1
I'm having trouble in decreasing the second number.
public class $1_8{
public static void main(String[] args){
int num1 = 9, num2 = 9;
for(int i = 9; i >= 1; i--){
for(int n = 1; n <=i; n++){
int sum = num1 * num2;
System.out.println(num1 + "*" + num2 + "=" + sum + "\t");
}
num1--;
System.out.println();
}
}
}

Front End Web Development Techdegree Graduate 84,738 PointsYou have two variables num1 and num2 for the multipliers, and also two variables i and n and you're using to keep track of how many times you've gone through a loop. I suggest just using num1 and num2 for both purposes.
public static void main(String[] args){
for(int num1 = 9; num1 >= 1; num1--){
for(int num2 = 9; num2 >= 1; num2--){
int sum = num1 * num2;
System.out.println(num1 + "*" + num2 + "=" + sum + "\t");
}
num1--;
System.out.println();
}
}
