用两个线程，一个输出字母，一个输出数字，交替输出A1B2C3D4…26Z

实现示例代码如下：

package com.mytest.Learning;
    
    public class jiaoti_print_syn { 
        public static void main(String [] args){ 
            final Object object = new Object();
            final char[] letter = { 'A'};
    
            new Thread(()->{ 
                synchronized (object){ 
                    for(int i=0; i<26; i++){ 
                        System.out.print(letter[0]++);
                        try { 
                            object.notify();
                            object.wait();
                        } catch (InterruptedException e) { 
                            e.printStackTrace();
                        }
                    }
                    object.notify();
                }
            },"t1").start();
    
            new Thread(()->{ 
                synchronized (object){ 
                for(int j=0;j<26;j++){ 
                    System.out.print(j);
                    try { 
                        object.notify();
                        object.wait();
                    } catch (InterruptedException e) { 
                        e.printStackTrace();
                    }
                }
                object.notify();
                }
            },"t2").start();
        }
    }

打印效果如下：
