java - If i call Insert method from C i want to get output "Now in Class B", But actually i get "Now in Class C" why? how can it be solved? -

public interface d{      public abstract string  joo();     public abstract string foo();     public bean tem(){       joo();     } }  public abstract class a{      protected abstract string  joo();     protected abstract string foo();     protected bean tem(){        joo();     }  }    public class b extends impliments d{  protected string joo(){     system.out.println("now in class b");     }  protected string foo(){     super.tem();     } }  public class c extends b{      protected string joo(){     system.out.println("now in class c");   }  protected string foo(){    super.tem();    }  public void insert(){  super.foo();   }  } 

if call insert method c want output "now in class b", "now in class c" why? how can solved? when calling foo method in class c ,i want output "now in class c".

you can't - @ least not without refactor.

here's code cleaned clearer. note @override indicates method overrides inherited method.

public abstract class {      protected abstract string joo();      protected abstract string foo();      protected string tem() {          return joo();     } }  public class b extends {      @override     protected string joo() {         system.out.println("now in class b");         return "from b";     }      @override     protected string foo() {         return super.tem();     } }  public class c extends b {      @override     protected string joo() {         system.out.println("now in class c");         return "from c";     }      @override     protected string foo() {         return super.tem();     }      public void insert() {         super.foo();     }  }  public void test() {     c c = new c();     // valid - prints in class c     c.insert();     // valid - prints in class c     c.foo(); } 

see how insert on c calls b.foo calls a.tem calls joo. a.joo implemented in b overriden in c final result c.joo.
