Differences between inheriting the thread class and implementing the Runnable interface in Java

Differences between inheriting the thread class and implementing the Runnable interface in Java There are two ways to create a thread in Java: 1. By inheriting the Thread class, override the Thread's run () method and place the Thread running logic in it 2. instantiate the Thread class by implementing the Runnable interface In practical application, we often use multithreading, such as the ticket sales system of the station. The tickets at the stati

is: thread-0 at the beginning, alternating main. When the index of the main thread reaches 100, it is until the end of thread-0. When the index of the main thread reaches 100, the tt thread is added to the main thread and becomes a single thread. Therefore, when the tt thread is executed, the main thread will not be executed until the tt thread is executed. 2. tt. join (1, 10000 ). the running result is: at the beginning, the tt thread and the main thread run alternately. When the index of the

that implements the Runnable interface. We know that "a class can have only one parent class, but it can implement multiple interfaces", so runnable has better extensibility.In addition, runnable can also be used for "sharing resources." That is, multiple threads are based on a single Runnable object, and they share resources on the Runnable object.Generally, it is recommended to implement multithreading through "Runnable"!thread and runnable examples of multithreading1.Thread Multithreaded Exa
