Observe Line 3 to 7:

private String name;

public void setName(String n){
this.name=name;
}

What you have done here is you are reassigning name to itself .

Your local variable is n so use
this.name=n;
Not this.name=name;

another option
public void setName(String n)

change variable n with name like
public void setName(String name){
then this.name=name; will mean assigning local variable to instance variable.

Happy learning ☺
