Getting Class type from String

Question

I have a String which has a name of a class say "Ex" (no .class extension). I want to assign it to a Class variable, like this:

Class cls = (string).class

How can i do that?

Answer 1

Class<?> cls = Class.forName(className);

But your className should be fully-qualified - i.e. com.mycompany.MyClass

Answer 2

eeh.. Class.forName(String classname) ?

Answer 3

Not sure what you are asking, but... Class.forname, maybe?

Answer 4

You can use the forName method of Class:

                Class cls = Class.forName(clsName);
                Object obj = cls.newInstance();

Answer 5

String clsName = "Ex";  // use fully qualified name
Class cls = Class.forName(clsName);
Object clsInstance = (Object) cls.newInstance();
