Sometimes we need to interrupt an executing thread at a specified point in time. For example, the thread that checks the sensor state every minute, and the rest of the time, the thread does not need to do anything. During this time, the thread does not need to use any of the computer's resources. After this time, and when the Java Virtual machine dispatches the thread, the thread continues to execute. To do

mechanisms for object-oriented programming code reuse, and the concept of Java polymorphism can be said to be "an interface, multiple methods." Java implements Run-time polymorphism based on dynamic method scheduling, which is a mechanism for invoking overloaded methods at run time rather than at compile time. The overridden overriding and overloaded overloading of methods are different manifestations of
