Runnable r = new Runnable() { public void run() { System.out.print(”Cat”); } }; Threadt=new Thread(r) { public void run() { System.out.print(”Dog”); } }; t.start(); What is the result?() A ...
Runnabler=()->System.out.println("Hello World!");Threadth=newThread(r);th.start(); 运行结果输出为Hello World,是不是很神奇,如果没有 Lambda 表达式,那么原来的代码可能如下 Runnabler=newRunnable(){@Overridepublicvoidrun(){System.out.println("Hello World!");}};Threadth=newThread(r);th.start...
Runnabler=newRunnable() {@Overridepublicvoidrun(){ System.out.println("Hello from thread"); } }; 或使用 lambda 表达式 Runnabler=() -> System.out.println("Hello from thread"); 2.2 创建 Thread 对象 通过两种方式创建: 将Runnable 对象作为 Thread 类的构造函数的参数 Threadt=newThread(r); 继...
public class ClassTest {public static void main(String[] args) {Printable printable = new Printable() {public void print() {System.out.println(getClass());}};printable.print();Person person = new Person();person.sayHello();Person person2 = new Person() {public void sayHello(...
//第二种创建RunnableRunnable r=newRunnable() { @Overridepublicvoidrun() {for(inti = 0; i < 10; i++) { System.out.println(Thread.currentThread().getName()+"--->"+"小华"+i); } } };newThread(r).start(); //第三种简化接口 ...
Runnable r=new Runnable(){ public void run() { while(true){ System.out.println("1111"); } } } Thread t = new Thread(r); t.start(); 1. 2. 3. 4. 5. 6. 7. 8. 9. 或者下面的形式也可以开启一个线程,也就是重写Thread类的run方法: ...
您的run方法接受一个Runnable实例，这解释了为什么run(new R())与R实现一起工作。
Runnable r = new Runnable() { public void run() { for (int i = 1; i <= 5; i++) { System.out.print(i + " "); } } }; Thread t = new Thread(r); t.start(); } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

mHandler = new Handler(); new Thread(new Runnable() { @Override public void run() { try { Thread.sleep(1000);//在子线程有一段耗时操作,比如请求网络 mHandler.post(new Runnable() { @Override public void run() { mTestTV.setText("This is post");//更新UI ...
