java - What class has access to my methods? -

my question today creating object, , other classes have access methods. trying larn threading, since jpanels don't back upwards threads have gotten confused.

i create simplified class this:

public class mymethodclass { public mymethodclass () { myclass myclass = new myclass(); } public void mymethod() { //do variables } }

so have new class object called myclass (myclass class, content not important). public, myclass have access mymethod?

if not, there way pass re-create mymethodclass myclass can utilize mymethod, knowing mymethodclass created myclass in first place?

if class myclass nested class, access mymethod?

myclass not able access methods within mymethodclass unless creates instance of , in case, that's bad idea.

you could pass myclass instance of mymethodclass via constructor or setter method, you'd improve using mutual interface, decouple 2 classes , improve reusability

start defining contract between 2 class (as interface)...

public interface somemethods { public void mymethod(); }

add ability pass implementation of somemethods myclass via it's constructor or setter method...

public class myclass { private somemethods somemethods; public myclass(somemethods somemethods) { this.somemethods = somemethods; } public void somework() { somemethods.mymethod(); } }

have mymethodclass implement somemethods interface , pass reference of myclass

public mymethodsclass implements somemethods { public mymethodclass () { myclass myclass = new myclass(this); } @override public void mymethod() { //do variables } }

just beware, it's not considered thought pass this other classes or methods within constructor, state of object may not realised , value methods/classes rely on may not yet initialised.
