Java callback function for each class method

Question

Is there a way in JAVA to call a callback function for every method of my class without calling the call explicitly

I do not want to do

public void foo()
{
   //some code
   callBackFunction()
} 

I'd like to do

public void foo()
{
   //some code
} 

and then the class recognizes that it should call the callBackFunction () function

x.foo();  // calls y.foo() implicitly
