3 ways to create Java threads and contrast __java
Four: Three ways to create a thread comparison
The way to implement the Runnable interface and the Calable interface is basically the same, the Knowledge Calable interface defines a method that has a return value and can declare an exception to be thrown. So they are grouped into one category. The difference between this approach and the inheritance thread approach is as follows:
@ Create the pros and cons of multithreading in the way that implements the interface:
1 The thread class knowledge implements the Runnable interface or the Calable interface, and can also inherit other classes.
2 in this way, multiple threads can share a target object, ideally suited for multiple identical threads to handle the same resource.
3 Disadvantage is: Programming comparison of the trouble, if you need to access the current thread, you need to call the CurrentThread () method.
@ Use the inheritance thread class to create the advantages and disadvantages of multithreading:
1 The disadvantage is that the thread class has been inherited, so you cannot inherit other parent classes.
2 Advantage is: The code is simple, you can access the current thread directly through this.
Through analysis, it is generally recommended to implement the interface to create multithreading.
