Question

Is is possible to check whether given Object item can be casted to some class? Is there any method which doesn’t throw an exception?

Answer 1

Yes, Class.isInstance(Object) and the related Class.isAssignableFrom(Class)

Example:

Object x = "foo";
Integer.class.isInstance(x); // => false
Integer.class.isAssignableFrom(x.getClass()); // => false

---

Edit: You said “method” so I assumed you meant an API method, but if you know the types at compile-time then you can simply use

x instanceof Integer // => false
