Thread: New Method array to String or just print as Array?

Hey guys,

i'm sure u're able to help me. I just tried to fill an array with some numbers, calculated by a other function.
I just tried to print this array as array, but it doesnt work.
Maybe its just about the main method.

public static void main(String[] args) {
    ggT(5);
    }
 
    public static int ggT(int a, int b) {
 
        while(a!=b){
            if(a>b) {
                a=a-b;
            } else {
                b=b-a;
            }
        }
        return a;
 
    }
 
    public static void ggT(int a) {
        int[][] array = new int[1000][2];
        for(int i=0; i<=1000; i++) {
            array[i][0] = i;
            array[i][1] = ggT(a,i);  
        } 
        for(int j=0; j<=1000; j++) {
            for(int z=0; z>=2; z++) {
                System.out.println(array[j][z]);
 
            }
        }
 
    }

Sry about the bad post, i just didnt find, how i can post source code properly.

Greetings Necator

it compiles, but it doesnt print anything. I just let it calculate for around 2 minutes. Should be enough time for this little work.

Thx for the link to the announcement, just edited it.

its the same result if u just take 10.
So u dont see any problems by checking it?

if i just ggT(5,23), it works properly, so i dont think the while loop is the problem.

ok, i tested it, the problem seems to be in this part

for(int i=0; i<=1000; i++) {
            array[i][0] = i;
            array[i][1] = ggT(a,i);

any suggestions?
the ggT parts seems to calculate forever, anyone got an idea?

i just put some in there aswell, it seemed to compile quite right. Also if i test ggT(2,23) (with 2 parameters), so it should take the method named the same (ggT) with 2 parameters, with the while loop, it works.

nah, just the while loop itself works, so i guess the problem is within the call of the method.

public static int ggT(int a, int b) {
        System.out.println(3);
        while(a!=b){
            if(a>b) {
                a=a-b;
            } else {
                b=b-a;
            }
        }System.out.println(4);
        return a;
 
    }

Both worked. So the while loop should work, if not there shouldnt be the 4 printed.

If i just put ggT(5) in, theres printed nothing,
if i put ggT(5,23) in (2 parameters) then both prints come once so in this case it works perfectly.

i got it, i just put i=0 in the for loop, so he calculated 1-0 endless in the while loop.
