Question

我正在为我的大学课程工作。我想对编程进行测试。我是java的新手，在你正确回答问题之后，我需要帮助来制作点数系统。我的想法是，如果你正确回答每一个问题，你都会得到一分。

我的代码：

package sandis_iesmins_kursadarbs;
import java.util.Scanner;


public class Sandis_iesmins_kursadarbs {

    public static void main(String[] args) {            
        int a; 

        Scanner intScan = new Scanner(System.in);

        String[] jaut = new String[3]; //jaut = is questions in latvian language
        jaut[0] = "Is java a programming language";
        //jaut[1] = "Kas ir prog1"; these are comments
        //jaut[2] = "Kas ir prog2"; these are comments
        System.out.println(jaut[0]);

        String[] atbildes = {"answers", "1)Yes", "2)No", "3)Maybe", "4)Dont know"}; //answer options
        for (String atb: atbildes) {
            System.out.println(atb);
        }
        System.out.println("Insert your answers");
        a = intScan.nextInt();
        //answer is just "yes" and now I want to add 1 point to my score. How can I do this?
    }

}

是否有任何人想要制作这种计数系统。仅供参考我将有10个大概的问题。

Answer 1

您可以保留一个跟踪分数的变量。

int score = 0;

/*
Ask your question here
*/

if(/*Correct answer*/)
    score++; // increment score

请查看基本的Java教程。找到一个here

Answer 2

如果我理解你的问题：

放入一个名为eg的整数＆＃34;计数器＆＃34;：

mvn clean package && mvn jar:jar failsafe:integration-test failsafe:verify

每次你想要添加的东西都可以：

int counter = 0;

在该计划中：

counter++;

Answer 3

您可以使用counters。创建名为＆＃39;得分的int变量，如果答案正确，则将其增加一点。这是一个例子：

package sandis_iesmins_kursadarbs;
import java.util.Scanner;


public class Sandis_iesmins_kursadarbs {
public static void main(String[] args) {            
    int a;
    int score = 0; 

    Scanner intscan = new Scanner(System.in);

    String [] jaut = new String[3]; //jaut = is questions in latvian language
    jaut[0] = "Is java a programming language";
    //jaut[1] = "Kas ir prog1"; these are comments
    //jaut[2] = "Kas ir prog2"; these are comments
    System.out.println(jaut[0]);

    String[] atbildes = {"answers", "1)Yes", "2)No", "3)Maybe", "4)Dont know"}; //answer options
    for(String atb: atbildes){
        System.out.println(atb);
    }
    System.out.println("Insert your answers");
    a=intscan.nextInt();
    //let's imagine that the correct answer is "Yes".
    if(a == 1){
       score++;
    }


}

不过，如果你想建立一个惩罚错误答案的系统，你可以这样做：

package sandis_iesmins_kursadarbs;
import java.util.Scanner;

public class Sandis_iesmins_kursadarbs {

public static void main(String[] args) {            
    int a;
    double score = 0.0;

    Scanner intscan = new Scanner(System.in);

    String [] jaut = new String[3]; //jaut = is questions in latvian language
    jaut[0] = "Is java a programming language";
    //jaut[1] = "Kas ir prog1"; these are comments
    //jaut[2] = "Kas ir prog2"; these are comments
    System.out.println(jaut[0]);

    String[] atbildes = {"answers", "1)Yes", "2)No", "3)Maybe", "4)Dont know"}; //answer options
    for(String atb: atbildes){
        System.out.println(atb);
    }
    System.out.println("Insert your answers");
    a=intscan.nextInt();
    //let's imagine that the correct answer is "Yes"
    if(a == 1){
      score++;
    //the system punishes you -0.25 for wrong answer
    }else{
      score -= 0.25;
    }
}


}
