Hi. I have a problem. I am totally beginner in Java. Now I'm learning Loops. please help me!

a+b+c=15 then a, b, c=? (PS: a, b and , c are not equal each other)
how can I solve this Problem Please help me?

a+b+c=15; then a , b and c are not equal each other. And a, b and c must be from 1 to 9. then find a=? b=? c=?
i think i should use 3 for loops. but i can't solve.
it can implement
1+5+9=15
1+6+8=15
1+8+6=15
1+9+5=15
2+4+9=15
2+5+8=15
2+6+7=15
2+8+5=15
2+9+4=15
................
...............
9+2+4=15
9+4+2=15

Help ?

all you can do is provide every possible solution. Here is a way to do it with loops. As you can see it starts with a= 0, it then enters the "b" loop with b = 0 lastly it enters the "c" loop starting with c = 0.
It will loop through for every possible combination of values. And print the ones that add up to 15.
CODE

A=1;
while(A <= 9)
{
    B = 1;
    while(B <= 9)
    {
        C = 1;
        while(C <= 9)
        {
            if(A + B + C == 15)
            {
                              System.out.print ln("A:" + A + "  B:" + B + "  C:" + C);
            }
               C++;
        }
        B++;
    }
    A++;
}
