Java：如何将同一字符串中的两个单词输出到单独的行上？

Question

I am trying to enter the first and last name in one string and then display the first and last name on separate lines. I thought the nextLine(); command would work but is not displaying the first and last name on separate lines

    String full_name;

    System.out.println("Please enter your first and last name?");

     full_name = c.nextLine();

    System.out.printf("Your name is: "+ full_name);

Answer 1

你可以尝试...

System.out.print("Your name is: "+ full_name.replace(" ", "\n"));

Answer 2

Presuming that c is a Scanner set to listen to System.in , then by virtue of it being on the input stream, it wouldn't have an effect on the output stream.

Instead, if you wanted to print the first and last name that was entered, and we presume that a first and last name is separated by a single space (may want logic for middle names), you can write this.

String[] brokenName = full_name.split(" ");
System.out.printf("Your name is:\n%s\n%s", full_name[0], full_name[1]);
