小编Kie*_*boz的帖子

在网上发现的那一刻使用此代码

 String welcome = "Would you like to play a game?";
 for (int i = 0; i < welcome.length(); i++) {
      System.out.println(welcome.charAt(i));

    }

很基本的东西，但是它真的可以很快地逐行打印出来，我该如何添加一个小暂停，并在上一个字符之后立即打印？最后，它只是说您想玩游戏吗？

我正在使用CMD和Sublime文本。

谢谢！

你可以在下面看到我有一个名为costperkm的变量,通常为0.08,然后我有一个基于数字的数组,然后围绕这些数字构建的第二个数组乘以costperkm,但是我得到错误; http://puu.sh/2sxi7

Scanner costscan=new Scanner(System.in);
    double costperkm = costscan.nextDouble();

double distarray[] = new double[5];

  distarray[0] = 850;
  distarray[1] = 1000;
  distarray[2] = 1250;
  distarray[3] = 1275;
  distarray[4] = 1350;
  distarray[5] = 2690;

double costarray[] = new double[5];

  costarray[0] = (distarray[0]*costperkm);
  costarray[1] = (distarray[1]*costperkm);
  costarray[2] = (distarray[2]*costperkm);
  costarray[3] = (distarray[3]*costperkm);
  costarray[4] = (distarray[4]*costperkm);
  costarray[5] = (distarray[5]*costperkm);

System.out.print(costarray[0]);
