String数组问题
现有一个数组
String[] str = new String[]{"A","B","C","D","E","F"};

输出为： -------------------------------
| A | B | C |
-------------------------------
| D | E | F |
-------------------------------


这个线都是连在一起的，是一个两行三列表格，我这里不想往上传图片了，就随便画了一下



[解决办法]

Java code

String[] str = new String[]{"A","B","C","D","E","F"};        for (int i = 0; i < str.length; i++) {            if(i>0&&i%3==0) {                System.out.println();            }            System.out.print(str[i] + " ");        }
[解决办法]
就是循环，三个元素换一次行
Java code
String[] str = new String[]{"A","B","C","D","E","F"};String line = "-------------"; //计算好元素占的横向空间System.out.println(line);System.out.print("|");for (int i = 0; i < str.length; i++) {    System.out.printf(" %s |", str[i]);    if ((i+1)%3 == 0) { //3个元素换一次行，并打印第一个竖线        System.out.printf("\n%s\n%s", line, i==str.length-1 ? "" : "|");    }}
