要求

使用生產者和消費者模式實現，交替輸出： 假設只有兩個線程，輸出以下結果：t1-->1t2-->2t1-->3t2-->4t1-->5t2-->6....要求：必須交替，并且t1線程負責輸出奇數。t2線程負責輸出偶數。兩個線程共享一個數字，每個線程執行時都要對這個數字進行：++

代碼

public class Test {public static void main(String[] args) {Num num = new Num(1);Thread t0 = new Thread(new OddNumber(num));t0.setName("奇數");Thread t1 = new Thread(new EvenNumber(num));t1.setName("偶數");t0.start();t1.start();} } public class OddNumber implements Runnable{private Num number;public OddNumber(Num number) {this.number = number;}public OddNumber() {}@Overridepublic void run() {while (true){synchronized (number){if (number.i % 2 != 0){System.out.println(Thread.currentThread().getName() + "--->" + number.i++);}else{number.notify();try {number.wait();} catch (InterruptedException e) {e.printStackTrace();}}}try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}} } public class EvenNumber implements Runnable{private Num number;public EvenNumber(Num number) {this.number = number;}public EvenNumber() {}@Overridepublic void run() {while (true){synchronized (number){if (number.i % 2 == 0){System.out.println(Thread.currentThread().getName() + "--->" + number.i++);}else{number.notify();try {number.wait();} catch (InterruptedException e) {e.printStackTrace();}}}try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}} } public class Num {int i;public Num(int i){this.i = i;} }
