Hi guys,
Im trying to compile this class below, but its just not working, it keeps sating 'missing return statement' int the method declaration line. Can u see to check if there is anything missing in my code or if iv done something wrong??
Thanks!
public class swapping {
public int trade(int []a, int b){ //says theres a missing return statement
int temp=0;
for (int n = 1; n < b; n++) {
for (int m = 0; m < b - 1; m++) {
if (a[m] > a[m] + 1) {
temp = a[m];
a[m] = a[m+1];
a[m+1] = temp;
return a[m];
}
}
}
}
}

hello everyone,
Your class main is missing and you added an extra bracket at the end
Yours Sincerely

Well I'm sure that i_me_roo probably has a main and extra bracket at the end. The compiler complaint was about return statements.
i_me_roo if you look at the code, you'll see that it is possible to go straight through the function without hitting the return statement. This is what the compiler is complaining about. The function returns an int, so all paths of execution must have a return value;
My suggestion is to have a 'return ERROR', or 'return 0', or 'return -1' after the for loops if you never intend to reach that line of execution. This is the best advice I can think of since I have no idea about the context of the function you wrote.

for (int n = 1; n < b; n++) {
for (int m = 0; m < b - 1; m++) {
if (a[m] > a[m] + 1) {
temp = a[m];
a[m] = a[m+1];
a[m+1] = temp;
return a[m];
}
}
}
return 0;
}
}Now it'll run well.
