无线程同步:
存储数据:
1 public class Storage { 2 int data; 3 4 public int getData() { 5 return data; 6 } 7 8 public void setData(int data) { 9 this.data = data; 10 } 11 12 }
产生数据:
1 public class Counter implements Runnable { 2 private Storage storage; 3 4 public Counter(Storage storage) { 5 this.storage = storage; 6 } 7 8 int count = 0; 9 10 @Override 11 public void run() { 12 while (true) { 13 14 storage.setData(count); 15 System.out.println("Storage data set:" + count); 16 17 try { 18 Thread.sleep((int) (Math.random() * 1000)); 19 } catch (InterruptedException e) { 20 21 e.printStackTrace(); 22 } 23 count++; 24 } 25 26 } 27 28 }
读取数据:
1 public class Printer extends Thread { 2 private Storage storage; 3 4 public Printer(Storage storage) { 5 this.storage = storage; 6 } 7 8 public void run() { 9 while (true) { 10 11 System.out.println("Storage data print:" + storage.getData()); 12 13 try { 14 Thread.sleep((int) (Math.random() * 1000)); 15 } catch (InterruptedException e) { 16 17 e.printStackTrace(); 18 } 19 20 } 21 22 } 23 24 }
测试类:
1 public class TestPrint { 2 3 public static void main(String[] args) { 4 Storage storage = new Storage(); 5 6 Counter counter = new Counter(storage); 7 Thread th1 = new Thread(counter); 8 9 Printer th2 = new Printer(storage); 10 th1.start(); 11 th2.start(); 12 } 13 14 }
运行结果:
1 public class Storage { 2 int data; 3 private boolean getable; 4 5 public synchronized int getData() { 6 while (getable == false) { 7 try { 8 wait(); 9 } catch (InterruptedException e) { 10 e.printStackTrace(); 11 } 12 } 13 getable = false; 14 notifyAll(); 15 return data; 16 } 17 18 public synchronized void setData(int data) { 19 20 while (getable == true) { 21 try { 22 wait(); 23 } catch (InterruptedException e) { 24 } 25 } 26 this.data = data; 27 getable = true; 28 notifyAll(); 29 } 30 31 }
运行结果:
