multithreading - Synchronizing two methods in Java -

i have class one:

public class iclass{ public void draw(){...}; //is called periodically rendering thread public void foo(){...}; //is called asynchronously thread(it ontouchevent() method example) }

i want foo() method wait until draw method finished , vice versa. how can in java?

regards

make methods synchronized.

public synchronized void draw() { system.out.println("draw"); } public synchronized void foo() { system.out.println("foo"); }

or synchronize on same object.

private static final object syncobj = new object(); public void draw() { synchronized (syncobj) { system.out.println("draw"); } } public void foo() { synchronized (syncobj) { system.out.println("foo"); } }
