Thread class, to perform tasks:
package com.yonyou.sci.gateway.exec; import java.util.concurrent.Callable; public class CallableTask<I extends Number> implements Callable<Integer> { private Integer num; public CallableTask () {} // use the received configuration parameters embodiment public CallableTask (Integer NUM) { the this .num = NUM; } @Override public Integer call () { COUNT Integer = 0 ; for ( int I =. 1; I <= NUM; I ++ ) { // The parameters passed iteratively adding COUNT = COUNT + I; } return count; } }
To perform the above tasks using a thread pool mode:
package com.yonyou.sci.gateway.exec; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.Future; /** * Use a thread pool to achieve parallel computing * / Public class TaskMain { public static void main (String [] args) throws Exception { // create a fixed length of thread pool ExecutorService Executors.newFixedThreadPool ES = (2 ); // use the thread pool mode, a thread of execution subclass Future <Integer> R1 = es.submit ( new new CallableTask <Integer> (100 )); Future<Integer> r2 = es.submit(new CallableTask<Integer>(200)); // get the result of the calculation and print out System.out.println (r1.get ()); System.out.println(r2.get()); // close the thread pool es.shutdown (); } }
