编写Java程序输入样式为Zhong wen ming的人名以 Ming,Zhong.W 的形式打印出来。其中.W是中间单词的首字母例如输入”Willian Jefferson Clinton“,输出形式为Clinton,Willian.J public static void main(String[] args) {try {englishName(Xiao Mo Nian);englishName(Willian Jefferson Clinton);} catch (Exception e) {System.out.println(e.getMessage());}}public static void englishName(String name){if(namenull){throw new RuntimeException(输入姓名不能为空);}String[] spilt name.split( );if(spilt.length!3){throw new RuntimeException(您输入的姓名格式不正确);}String twoSpilt new String(spilt[1]);char lastNameOne twoSpilt.charAt(0);lastNameOne isprimeChar(lastNameOne);for (int i 0; i spilt.length; i) {if(i spilt.length-1){System.out.println(spilt[i],spilt[0].lastNameOne);}}}public static char isprimeChar(char twoChar){char reverChar twoChar;if(!(twoCharAtwoCharZ)){reverChar (char)(twoChar-32);}return reverChar;} 打印结果 第二种实现方法
public static void englishName(String name){String[] spilt name.split( );if(spilt.length!3){throw new RuntimeException(输入的格式不正确);}if(namenull){throw new RuntimeException(输入不能为空);}
// String formatStr %s,%s.%c;
// String info String.format(spilt[2],spilt[0].spilt[1].toUpperCase().charAt(0));String info String.format(%s,%s.%c,spilt[2],spilt[0],spilt[1].toUpperCase().charAt(0));System.out.println(info);}
