今天聊一聊Java语言相关的编程面试题，你是否遇到过直接电脑上机写代码，或者是给你一张白纸一支笔，现场让你手写代码？小编总结了部分Java编程类题目，如下：

**1、Java面试题：输出9\*9乘法表**  
  
**2、Java面试题：编写程序在控制台输出斐波那契数列前20项，每输出5个数换行**

**3、Java面试题：给定一个字符串数组，判断每个字符出现多少次？**

**4、Java面试题：两个数组合并排序的java实现**

**5、Java面试题：两个有序数组合并到一个有序数组(时间复杂度低)**  
  
**6、Java面试题：统计一个字符串中最长连续子串**

**7、Java面试题：输出固定长度n的数字+字母的字符串**

对于手写编程题你怎么看，对于上面的Java题目，你有什么好的答案？欢迎留言讨论。

另外还有一些关于Java的面试知识，不知你有没有遇到过，整理如下：  
**1、==与equals的区别与联系**  
  
**2、Java实现两个字符串的比较**

**3、Java重写与重载的区别**  
  
**4、浅谈JDK、JRE、JVM区别与联系**
