Question

嗨，我正在尝试制作一个问题游戏来尝试我的知识和能力无论如何，我试图使用整数作为点和用户的每个问题答案得到了一些特别的积分无论如何我试图这样做

      switch (Ques){ case 1 : //first question about India and where it is in the map
          System.out.println("in what continent India is?");
          Scanner IndiaAns = new Scanner(System.in); //Scanner to receive user answer
          String IndiaAns2 , IndiaAnswer ; //strings to be used to receive user input and matching with the correct ones
          IndiaAns2 = IndiaAns.nextLine(); //Scanner will work here and receive...
          IndiaAnswer = "asia"; //the correct answer here and will be matched with user ones
          if (IndiaAns2 == IndiaAnswer) 
          {int Twopoints = 2; Points = + Twopoints; } else{}

          case 2:
          System.out.println("the Appstore founds in any phone model?");
          Scanner Appstore =new Scanner(System.in);
          String AppstoreAns1 ,AppstoreAns2; //strings saving 
          AppstoreAns1 = Appstore.nextLine(); //Scanner
          AppstoreAns2 = "iphone"; //matching with user answer
          if (AppstoreAns1 == AppstoreAns2)
          { int Threepoints = 3; Points = +Threepoints;} else { Points = +0;}

..还有另外两种情况，并且整数不在代码示例区域中的点是在上面的任何方式，如果完整的代码是必要的我会把它放在

Answer 1

关于您的代码，

  if (IndiaAns2 == IndiaAnswer) 
          {int Twopoints = 2; Points = + Twopoints; } else{}

应该像

 if(indiaAns2.equals(indiaAnswer)){
  points += QUESTION_1_POINTS;
 }

QUESTION_1_POINTS定义为常量，如`

public static final int  QUESTION_1_POINTS =2;

您要分配给points变量points + QUESTION_1_POINTS。

points += someInteger   --> points = points + someInteger

一些建议，

1）关注Java Code Conventions，变量名以小写

开头

2）对于对象比较，始终使用equals()而不是== 例如：

更改

if (IndiaAns2 == IndiaAnswer)

为：

if (indiaAns2.equals(indiaAnswer))

3）你需要制作开关声明

switch(condition){
case 1:
//code
break;
case 2:
//code 
break;
default:// some code;
}
