Invalid forward reference to member 'identifier'
The compiler detected an attempt to initialize a variable with another variable that had not yet been defined. To avoid this situation, reverse the field declarations order so that a variable that is referenced by another is defined first.
The following example illustrates this error:
public class Simple {
private static int i = j;
// error: 'j' not yet defined
private static int j = 0;
}
The following shows the correct way to initialize a field using another field in the same class:
public class Simple{
private static int j = 0; //field is instantiated and populated
private static int i = j; //with 'j' properly set, 'i' can be set
}
