Java give a class as parametre

Question

How can I give a class as a parametre in a method that I can then make one like that:

Type obj = new Type();

is that possible?

Answer 1

Yes it is possible:

MyClass.class

Let's say you have this method:

private void doSomething(Class cls) {}

you'd call with

doSomething(MyClass.cls);

Answer 2

You can do it different ways.

1. Pass a string parameter with full ClassName:

   void someMethod(String className) {    // className like "com.mypackage.Type"
       Type obj = (Type)Class.forName(className).newInstance();    
   }
   

2. Pass a Class type:

   void someMethod(Class clazz) {    // clazz is Type.class
       clazz.newInstance();
   }
