how to lock my Method

[saipraneeth nallapareddy]

hello ranchers

I have a scenario where when a call to particular method is being invoked it shouldn't be able to be invoked by other instances.Take a look into the following code.

public class MyClass{
public synchronized void logic(){
//some functionality
Thread.sleep(10000);//want to see if other invocation is possible during this time.
}
}

public class Test{
public static void main(String[] args){
MyClass x=new MyClass();
x.logic();
}
}

public class Test2{
public static void main(String[] args){
MyClass y=new MyClass();
y.logic();
}
}

my question is the logic method which has been synchronized should not be able to be invoked untill the first invocation finishes it's execution then realized that it's completely a different object so it forms a different entries on the heap which will reffered by x & y.
But i want the invocation of y to be restricted when x is using the logic method, what are the changes to be undergo.

Use the same instance, use a synchronized static method or use a static lock. That should work.
