英文:
Java - compilation error - cannot find symbol - variable Terminal
问题
我刚开始学习Java。在编译以下代码时遇到了问题。
public class Conversion {
public static void main(String[] args) {
double euros;
double dollars;
System.out.println("欧元总数？");
euros = Terminal.lireDouble();
dollars = euros * 1.118;
System.out.println("美元总数：");
System.out.println(dollars);
}
}
我得到了以下错误信息：
/Users/Mathieu/IdeaProjects/Conversion/src/com/company/Conversion.java:9:17
java: 找不到符号 符号: 变量 Terminal 位置:
类 com.company.Conversion
请问你能帮我吗？我的代码有什么问题吗？
提前谢谢你。

为了从用户获取输入，请使用以下代码：
import java.util.Scanner;
public class Conversion {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
double euros;
double dollars;
System.out.println("请输入欧元金额：");
euros = in.nextDouble();
dollars = euros * 1.118;
System.out.println("美元金额为：");
System.out.println(dollars);
}
}
Scanner用于从用户获取输入。
英文:
In order to get input from the user use this
import java.util.Scanner;
public class Conversion {
public static void main (String[] args) {
Scanner in = new Scanner(System.in);
double euros;
double dollars;
System.out.println("Sum in euros? ");
euros = in.nextDouble();
dollars = euros * 1.118;
System.out.println("Sum in dollars: ");
System.out.println(dollars);
}
}
Scanner is used to get input from the user
