我在这里有一个错误,我不知道它来自哪里.我在初学者的java课程是高中,所以我在这里还没有太多的经验.我有3个相互合并的程序.我有一个卡片类,可以创建一张扑克牌

public class Card

我在java中一次打印一个字符串时遇到问题.我必须输入一个字符串,每行输出一个字母.我的代码如下

import java.util.*;

public class StringToMultiLines 
{

public static void main(String[] args) 
{   
    String myString;
    int placeInString = 0;

    Scanner scan = new Scanner(System.in);

    System.out.println("Please enter a string.");
    myString = scan.nextLine();

    while(placeInString <= myString.length())
    {
        System.out.println("" + myString.substring(placeInString));
        placeInString ++;


    }
}

}

这ouptuts以下'请输入一个字符串.你好你好ello llo lo o

我也尝试过没有运气

System.out.println("" + myString.subsstring(0, placeInString));

和

 System.out.println("" + myString.subsstring(placeInString, placeInString));
