Need Help with two functions

[nickels]

Well my program is to convert an octal number to the decimal form. Im not that far into it because i cant get the two functions in without a compile error coming up. Heres what i got so far.

import java.util.Scanner;
 
public class test
{
public static void main ( String args[] )
 {
Scanner in = new Scanner ( System.in );
int value = 0;
 
while ( ( value < 1 ) || ( value > 99999999 ) )
 {
System.out.print ("Enter up to an 8-digit octal number and I'll convert it: ");
value = in.nextInt();
 }
}
 
public static int convert ( int value )
{
 
int a, b, c, d, e, f, g, h, num1 = 100000000, num2 = 10000000, num3 = 1000000, num4 = 100000, num5 = 10000, num6 = 1000, num7 = 100, 
num8 = 10, num9 = 1;
 
a = value % num1 / num2;
b = value % num2 / num3;
c = value % num3 / num4;
d = value % num4 / num5;
e = value % num5 / num6;
f = value % num6 / num7;
g = value % num7 / num8;
h = value % num8 / num9;
 
}
 
}

this is the error that comes up..


test.java:36: missing return statement
}
^
1 error

If i try to fix it i just get more errors. Help is greatly appreciated.

When you write, public static int convert (... you are saying that the method convert returns an int. The compiler therefore expects to find a return statement in that method which returns a value of type int. If the compiler doesn't find that return then it will tell you that your code is missing a return.

Here's a hint: check out the Integer.parseInt() methods; they're static methods.
