创建线程的基本方式1
package com.edu.threaduse;public class Demo01 {public static void main(String[] args) throws InterruptedException {//创建Cat对象可以当线程使用Cat cat new Cat();cat.start();//启动线程//使用run的话是主线程里面的一个普通方法,只有run执行完毕才结束//说明:当main线程启动一个子线程Thread-0,主线程不会阻塞会继续执行for (int i 0;i10;i){System.out.println(主线程ii);Thread.sleep(1000);}}
}
//通过继承Thread类创建线程
/*
当一个类继承类Thread类该类就可以当做线程使用
我们会重写run方法写上自己的业务代码
run Thread类实现Runnable接口的run方法*/
class Cat extends Thread{Overridepublic void run() {int time 0;while(time80){//重写run方法写上自己的业务逻辑//该线程每隔1秒在控制台输出喵喵我是小猫咪;System.out.println(喵喵,我是小猫咪线程名称Thread.currentThread().getName());//让线程休眠1stry {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}}
}创建线程的基本方式2
package com.edu.threaduse;public class Demo02 {public static void main(String[] args) {
// Dog dog new Dog();
// //dog.start()无法使用
// Thread thread new Thread(dog);
// thread.start();Tiger tiger new Tiger();ThreadProxy threadProxy new ThreadProxy(tiger);threadProxy.start();}
}
class Animal{}
class Tiger extends Animal implements Runnable{Overridepublic void run() {System.out.println(老虎);}
}
class ThreadProxy implements Runnable{ //看成一个Thread代理类private Runnable target null;//属性Overridepublic void run() {if(target!null){target.run(); //运行类型为Tiger}}public ThreadProxy(Runnable target) {this.target target;}public void start(){start0();}public void start0(){run();}
}class Dog implements Runnable{ //通过实现Runnable接口实现线程Overridepublic void run() {while(true){System.out.println(小狗叫);try {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}}
} 售票超卖
package com.edu.ticket;public class SellTicket {public static void main(String[] args) {SellTick02 sellTick02 new SellTick02();new Thread(sellTick02).start();new Thread(sellTick02).start();new Thread(sellTick02).start();}
}//class SellTick01 extends Thread{
// private static int ticketNum 100;
//
// Override
// public void run() {
//
// while (true){
// if (ticketNum0){
// System.out.println(售票结束);
// break;
// }
// System.out.println(售出一张还有:--ticketNum张);
// try {
// Thread.sleep(1000);
// } catch (InterruptedException e) {
// throw new RuntimeException(e);
// }
// }
// }
//}
class SellTick02 implements Runnable{private int ticketNum 100;Overridepublic void run() {while (true){if (ticketNum0){System.out.println(售票结束);break;}System.out.println(售出一张还有:--ticketNum张);try {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}}
}线程终止
package com.edu.exit;public class ThreadExit_ {public static void main(String[] args) throws InterruptedException {T t1 new T();t1.start();//主线程休眠10s再通知Thread.sleep(10*1000);t1.setLoop(false);}
}
class T extends Thread{private boolean loop true;Overridepublic void run() {while(loop){try {Thread.sleep(50);} catch (InterruptedException e) {throw new RuntimeException(e);}System.out.println(AThread 运行中...);}}//方便主线程控制public void setLoop(boolean loop) {this.loop loop;}
}常用方法 package com.edu.method;public class ThreadMethod_ {public static void main(String[] args) throws InterruptedException {T t new T();t.setName(老虎);t.setPriority(Thread.MIN_PRIORITY);System.out.println(t.getName());t.start();//主线程打印hi然后中断子线程for (int i 0;i5;i){Thread.sleep(1000);System.out.println(HI);}t.interrupt(); //中断t的休眠}
}
class T extends Thread{Overridepublic void run() {while (true){for (int i 0;i100;i){System.out.println(Thread.currentThread().getName()吃包子);}try {System.out.println(Thread.currentThread().getName()休眠中);Thread.sleep(20000);} catch (InterruptedException e) {//当线程执行道一个中断方法时可以加入自己的业务代码System.out.println(Thread.currentThread().getName()被中断了);}}}}package com.edu.method;public class ThreadMethod02 {public static void main(String[] args) throws InterruptedException {T1 t1 new T1();t1.start();for (int i 0;i20;i){if(i5){Thread.yield();//t1.join}System.out.println(HIi);Thread.sleep(1000);}}
}
class T1 extends Thread{private int loop 20;Overridepublic void run() {while (loop--0){System.out.println(Hello: loop);try {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}}
}package com.edu.method;public class ThreadMethod03 {public static void main(String[] args) throws InterruptedException {T3 t new T3();Thread t1 new Thread(t);for (int i 1 ;i10;i) {System.out.println(hi:i);if (i5){t1.start();t1.join();}Thread.sleep(1000);}System.out.println(主进程结束);}
}
class T3 implements Runnable{Overridepublic void run() {for (int i1;i10;i){System.out.println(HELLO:i);try {Thread.sleep(1000);} catch (InterruptedException e) {throw new RuntimeException(e);}}System.out.println(子线程结束);}
}
