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] + " "); }
------解决方案--------------------
就是循环,三个元素换一次行
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 ? "" : "|"); } }
