int to string??

[gelle cerda]

so how about this message:
The method "java.lang.String getCoinName(int coinName);" must contain a return statement with an expression compatible with type "String".
I am creating a method with an original int value from the main method and it must return a string.
how can i do that?

It means that you're trying to read a variable before assigning a value to it. A trivial example:

int i;
int j = i; // You'll get this error here.

A trickier example:

int i;
if (someFunctionCall())
  i = 3;
int j = i; // Again, you'll get that error here

In the second example i may have been assigned to before the value is assigned to j, but it also may not have been.

Make sense?

To an outsider reading this thread, my first post above must seem very odd. I should explain that the poster asked a questiont, and when I answered it aobove, edited his original message and replaced it with a completely different question!

In any case, your method could look something like

String getCoinName(int coin) {
  if (coin == 5)
    return "nickel";
  else
    return "something else";
}

Does this help?
