String name = "Anima"; if (name instanceof String) System.out.println("name is String" ); if (String.class.isInstance(name) ) System.out.println("instance of String" ); Class<?> nameCl = name.getClass(); System.out.println( nameCl.getSimpleName() ); System.out.println( nameCl.getName() ); System.out.println( nameCl.getTypeName() ); System.out.println( nameCl.toString() ); System.out.println( nameCl );

Class<?> is type of class named 'Class' and it using one parameter of generic type instead ? can be eg String, but in this code we don't know what type there is so there is ? wildcard and java get the type from name variable
