- mkross 14y ago// In Java, all instances of Object are also a monitor. // See https://en.wikipedia.org/wiki/Monitor_%28synchronization%29 Foo myMonitor = new Foo() // To "enter" a monitor, you use 'synchronized'. synchronized (myMonitor) { // Inside the monitor, we could do a Thread.sleep. Thread.sleep(100); } This is a very simplistic problem case. However, it is very possible for this to become a bigger problem. Because I can call arbitrary code when "inside" a monitor, it is very possible to call a method that does a sleep incidentally. (e.g. many implementations of IO operations will require some sort of sleep.)
