Question

public class Test {

public static void main(String[] args) {

    String name = "John King IV. Cena";

    int start = name.indexOf(' ');
    int end = name.lastIndexOf(' ');

    String firstName = "";
    String middleName = "";
    String lastName = "";

    if (start >= 0) {
        firstName = name.substring(0, start);
        if (end > start)
            middleName = name.substring(start + 1, end);
        lastName = name.substring(end + 1, name.length());
    }

    System.out.println(firstName);
    System.out.println(middleName);
    System.out.println(lastName);
}
}

在上面的代码中，我不想要中间名。我想从用户那里得到全名，然后它必须像firstname和lastname一样分开。

您可以尝试String split方法来执行此操作：

String name = "John King IV. Cena";          
String []nameArray=name.split("\\s+");

System.out.println("FirstName  "+nameArray[0] );
System.out.println("LastName  "+nameArray[nameArray.length-1]);

获取用户的全名
