missing return statement

Aug 18th, 2004

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.

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]; 
        }
      }
    }
    return 0;
  }
}
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]; 
        }
      }
    }
    return 0;
  }
}

Now it'll run well.

hi everyone i'm new to programming and i have to say its fun and frustrating at the same time could anyone help me fix this??

// Exercise5_2.java: Create a method for summarizing digits in an int

public class Exercise5_2 {
public static void main(String[] args) {

System.out.print("Enter a number: ");
long value = input.nextInt();

System.out.print(t);

}

//FILL IN THE METHOD

This is a 5 year old thread. That were you thinking posting here? Do you random peek threads and start writing irrelevant things in them?

If it says it is missing a return statement, then add one since your method is declared to return a String.
If you have any more questions start a new thread.

retun mySum;

}

You need to make a string out of the integer total and return it
