两线程进行操作：
package test5; public class Thread1 extends Thread{ private ProductConsume pc; public Thread1(ProductConsume pc){ this.pc=pc; } @Override public void run(){ pc.proDuct(); } }
1 package test5; 2 3 public class Thread2 extends Thread{ 4 5 private ProductConsume pc; 6 public Thread2(ProductConsume pc){ 7 this.pc=pc; 8 } 9 @Override 10 public void run(){ 11 pc.conSume(); 12 } 13 }
1 package test5; 2 3 public class Run { 4 5 public static void main(String[] args) { 6 ProductConsume pc=new ProductConsume(); 7 8 for(int i=0;i<1000000;i++){ 9 Thread1 t1=new Thread1(pc); 10 Thread2 t2=new Thread2(pc); 11 t1.start(); 12 t2.start(); 13 } 14 } 15 }
