Question

我希望打印姓氏，首字母只有大写字母，但我得到所有姓氏大写。我希望用户输入他们的名字，如乔丹托雷斯，并回馈托雷斯，J。

import java.util.*; // for Scanner

public class ProcessName { public static void main(String[] args) { String name;
  Scanner console = new Scanner(System.in); 
    System.out.print("Type your name: "); //send to user

  name = console.nextLine();
     String[] nameArray = name.split(" ");//split string into array

     String firstName = name.valueOf(name.charAt(0)).toUpperCase(); //get first letter 
     String lastName = name.substring(name.indexOf(" ") + 1).toUpperCase();

     String myName = lastName + ", " + firstName;//give last and first name

       System.out.println("Your name is: " + myName + ".");

我的输出是TORRES，J。

Answer 1

// Get the last name as entered by the user
String lastName = name.substring(name.indexOf(" ") + 1);

// Upcase the first character, then append the remaining characters
lastName = Character.toUpperCase(lastName.charAt(0)) + lastName.substring(1);
