Runnable优先级

　　

package workhome;

public class ThreadPriority {
    public static void main(String[] args) {
        MyThread a= new MyThread("S");
        System.out.println(a.getPriority());
        a.setPriority(10);
        MyThread b=new MyThread("B");
        b.setPriority(1);
        
        a.start();
        b.start();
    }
}

class MyThread extends Thread{
    private String name;
    public MyThread(String name) {
        this.name=name;
    }
    
    public void run() {
        System.out.println(name);
    }
}

优先级

package workhome;

public class Runnable2 {
    public static void main(String[] args) {
    
        /*
        new Thread(new Runnable() {
            public void run() {
                for(int i=0;i<10;i++) {
                    System.out.println(i);
                }
            }
        }).start();
        */
        new Thread() {
            public void run() {
                for(int i=0;i<100;i++) {
                    System.out.println(i);
                }
            }
        }.start();
    }
}

匿名类实现

package workhome;

public class Runnable1 {
public static void main(String[] args) {
        Runnable r=new Dog();
        new Thread(r).start(); 
}
}

class Animal{
    private String name;
    public String getName() {
        return name;
    }
    public void setName(String anme) {
        this.name=name;
    }
}

//Dog
class Dog extends Animal implements Runnable{
    public void eat() {
        System.out.println("like bone!");
    }
    
    public void run() {
        eat();
    }
}

Runnable接口让普通类实现多线程
