Java Programming

Hi,

I have a class composed by some methods, I want to find a way on for implicitly call a method in start and end of every method of my class without coding it.

example

this is my class :

public class MyClass {

public void a(){
...
}

public void b(){
...
}

}

call :
MyClass class = new MyClass();
class.a();


i want that when i do like below the execution will be like :

implicitCall();
a();
implicitCall();

is that possible?
Do you have any idea, on how to do that.

Thanks in advance
