there is no return statement

[gabriel]

an error tell me that there is no return statement .
I don't know the cause

Code:

public class FirstTest
{
public static void main()
{
int one = 0;
int two = 2;
add(a, b);

}
public static int add(int one, int two)
{
int c = a + b;
}
}

what's the problem?

[hardwired]

Code:

public static int add(int one, int two)
{
    int c = a + b;
    return c;
}

Every method in java must have a return type in its method signature. The add method has a return type of int which means that the method must return an int. i can call the add method with two arguemnts and get the sum of them back, it will return the sum to me: int x = add(5, 6);
The type returned from the method must match the return type declared in the method signature.
