Problem

Question

Hey guys!
Can you help me and tell me what ia wrong with tis code?
public class Program
{
public static void main(String[] args) {

int x=6;
int y=15;
int z;

if(x<y)
{
z=x;
}
else{
z=y;
}

if(z%x<=0 && z%y<=0){
System.out.println("z");
z-=z;
}
}
}

I need the fix, and I cant find it, it sais "No output"

Answer 1

Hi,
your result is No output because you don't print anything

Explaination:
x = 6 and y = 15 => x<y then z = 6

you want test that :
if(z%x<=0 && z%y<=0)
so z%x => 6%6 = 0 then z%x <= 0 return true
and z%y => 6%15 = 6 then z%y <= 0 return false
true && false return false
your test is always false then you won't execute System.out.println("z");

What do you really want to test ?

Answer 2

The code is fine and does what it should do.

It says no output because the if condition results in false.

if(z%x<=0 && z%y<=0)
The first condition is true because z is 6 and x is 6.

But the second one is false because z is 6 and y is 15.
So first one results in 0 but the second one results in 6

Answer 3

Oh right and I put the z-=z in the wrong spot.

Answer 4

Vhy isnt it working if i put z-=z in the next layer?

Answer 5

I wanna test if x and y can be divided by same number (being z)
So i put z-=z one layer down and it still isnt working.

Answer 6

if you want test if x and y can be divided by same number (being z), change your modulo expression
if (x%z == 0) && (y%z == 0){
System.out.println("x and y are divising by z");
}
else {
System.out.println("both x and y are not divising by z");
}

i don't understand why you want do z -= z
this return z = 0

Answer 7

z-=z is there because i wanna get the number that can be divided by both, if z=6 is not dividable, it will try 5,4,3.... until it gets the number that can be dividable by both, in this case 3.

Answer 8

if (x%z == 0) && (y%z == 0){
msg = x + " and " + y + " are divising by " + z;
System.out.println(msg);
}
else {
System.out.println("both " + x + " and " + y + " are not divising by " + z);
z -= 1; // or z--;
}

Answer 9

i forgot but you must include this code within a while loop with condition z>0

Answer 10

Oh okay, Ill try

Answer 11

It worked! Thanks!

Answer 12

What

Answer 13

I published it, can you tell me the name for it, I am not the best in English ..
And I made so that it tell all dividable numbers.
