Java中特定静态方法上的线程并行编程

Question

I have this code:

public final class AClass{   
    static Long x=0;
    public static Long aMethod(args...){

        //commands
        x = aMethod(args...);
        x += aMethod(args...);
        //commands
    }

}

I want to execute the two lines of code(the two calls of aMethod ) parallel with threads.

Answer 1

This is a relatively simple problem and the following code should solve your predicament

Thread thread1 = new Thread() {
   public void run() {
      x = aMethod(args...);
   }
};

Thread thread2 = new Thread() {
   public void run() {
     x += aMethod(args...);
   }
};

thread1.start();
thread2.start();

Then you join the result with:

thread1.join();
thread2.join();

These 2 lines of code will throw an InterruptedException and will need to be handled with a try/catch
