how to define a method that takes a generic type as parameter from certain parent class

Question

I know that I can use Object as the parameter type , but then I have to cast to the class I want.

My question is: Can I do something like that

public void doSomething( <T extends Person> person ) { Student student = person ; }

like what we can achieve with return type in java

public <T extends Person> T findPerson() { ;;;;;} Student student = findPerson(1) ;

English is not my native language, so sorry if the question is not clear enough

You can use it like

public <T extends SomeClass> void doSomething(T item){ //Do something item.number = 4; }

Where:

class SomeClass{ public int number; }
