多線程——實現Runnable接口實現一個多線程

實現Runnable接口實現一個多線程

Runnable接口源碼：

package java.lang;
//Runnable接口源碼只有一個run方法
public interface Runnable {public abstract void run();
}

實現Runnable的兩個多線程類：

public class RunnableThread1 implements Runnable {@Overridepublic void run() {for (int i = 0; i < 5; i++) {System.out.println(Thread.currentThread().getName() + ":線程啟動....");try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}
}
public class RunnableThread2 implements Runnable {@Overridepublic void run() {for (int i = 0; i < 5; i++) {System.out.println(Thread.currentThread().getName() + ":線程啟動....");try {Thread.sleep(2000);} catch (InterruptedException e) {e.printStackTrace();}}}
}

?

測試：

public class TestThread {public static void main(String[] args) {RunnableThread1 thread1 = new RunnableThread1();RunnableThread2 thread2 = new RunnableThread2();Thread t1 = new Thread(thread1, "線程1");Thread t2 = new Thread(thread2);// 線程2為系統命名// 不能再此處調用sleep()方法
t1.start();t2.start();}
}
結果：
Thread-0:線程啟動....
線程1:線程啟動....
線程1:線程啟動....
Thread-0:線程啟動....
線程1:線程啟動....
線程1:線程啟動....
Thread-0:線程啟動....
線程1:線程啟動....
Thread-0:線程啟動....
Thread-0:線程啟動....
