'instanceof' operator expected class or array
The compiler detected the instanceof operator applied to a type that did not resolve to a class or array. The instanceof operator is used to determine if identifier is an instance of a specific class or array. Ensure the lvalue used with the instanceof operator references a class instance or array and the rvalue references a valid class name or array and compile again.
The following example illustrates this error:
public class Simple {
public void method1() {
Simple2 obj = new Simple2();
if (obj instanceof int) // error: 'int' is not a class name
// do something meaningful
}
}
class Simple2 {
// do something meaningful
}
