Test if object is instanceof a parameter type

Question

Is there a way to determine if an object is an instance of a generic type?

public  test(Object obj) {
    if (obj instanceof T) {
        ...
    }
         


        

Answer 1

The only way you can do this check is if you have the Class object representing the type:

Class type; //maybe passed into the method
if ( type.isInstance(obj) ) {
   //...
}
