Java线程的使用

1、实现Runnable接口，实现run方法

public class ThreadTest {public static void main(String[] args) {try {// 调用方法本身\主线程运行MyRunnable1 run1 = new MyRunnable1("test1");run1.run();// 新开线程Thread t1 = new Thread(run1);t1.setName("t1");t1.start();} catch (Exception ex) {ex.printStackTrace();}}}class MyRunnable1 implements Runnable {private String value;public String getvalue() {return value;}public void setvalue(String value) {this.value = value;}public MyRunnable1(String value) {this.value = value;}public void run() {System.out.println("线程ID:" + Thread.currentThread().getId());System.out.println("线程Name:" + Thread.currentThread().getName());System.out.println("Runnable-Value:" + value);System.out.println("-----------------------------------------------------------------");}}

2、直接继承Thread类，重写run方法

public class ThreadTest {public static void main(String[] args) {try {// 主线程System.out.println("线程ID:" + Thread.currentThread().getId());System.out.println("线程Name:" + Thread.currentThread().getName());// 新开线程MyThread t3 = new MyThread("test3");t3.setName("t3");t3.start();} catch (Exception ex) {ex.printStackTrace();}}}class MyThread extends Thread {private String value;public String getvalue() {return value;}public void setvalue(String value) {this.value = value;}public MyThread(String value) {this.value = value;}@Overridepublic void run() {super.run();System.out.println("线程ID:" + Thread.currentThread().getId());System.out.println("线程Name:" + Thread.currentThread().getName());System.out.println("MyThread-value:" + value);System.out.println("-----------------------------------------------------------------");}}

3、采用匿名类方式，其实也是实现接口Runnable

public class ThreadTest {public static void main(String[] args) {try {Thread t2 = new Thread(new Runnable() {public void run() {System.out.println("线程ID:" + Thread.currentThread().getId());System.out.println("线程Name:" + Thread.currentThread().getName());System.out.println("匿名类时间:" + java.util.Calendar.getInstance().getTimeInMillis());System.out.println("-----------------------------------------------------------------");}});t2.setName("t2");t2.start();} catch (Exception ex) {ex.printStackTrace();}}}
