使用两个线程分别打印1 ~ 25,A ~ Z按12A34B56C78D的顺序输出

public class ThreadPrint {
   	public static void main(String[] args) {
   		final Object lock = new Object();		new Thread(new Runnable() {
   			public void run() {
   				synchronized (lock) {
   					for (int i = 1; i < 26; i++) {
   						if (i % 2 != 0) {
   							System.out.print(i);						} else {
   							System.out.print(i);							try {
   								lock.wait(1000);							} catch (InterruptedException e) {
   								e.printStackTrace();							}						}					}				}			}		}).start();		// 睡10ms保证能进入线程A		try {
   			Thread.sleep(10);		} catch (Exception e) {
   			e.printStackTrace();		}		new Thread(new Runnable() {
   			public void run() {
   				synchronized (lock) {
   					for (int i = 0; i < 26; i++) {
   						//大写A~Z						System.out.print((char) (65 + i));						//小写a~z//						System.out.print((char) (97 + i));						try {
   							lock.wait(1000);						} catch (InterruptedException e) {
   							e.printStackTrace();						}					}				}			}		}).start();	}}
