两个线程，一个为123456，一个为ABCDEF、交替打印出1A2B3C...

1、使用LockSupport实现：

public class T_TurnLockSupport {

    private static final char[] nums = "123456".toCharArray();
    private static final char[] chars= "ABCDEF".toCharArray();

    static Thread N=null, C=null;

    public static void main(String[] args) {

        N = new Thread(()->{
            for (char n:nums) {
                System.out.print(n);
                LockSupport.unpark(C);
                LockSupport.park();
            }
        },"N");

        C = new Thread(()->{
            for (char c:chars) {
                LockSupport.park();
                System.out.print(c);
                LockSupport.unpark(N);
            }
        },"C");

        N.start();
        C.start();
    }
}
