java - 尝试将用户输入与文本文件进行比较，然后在java上读取该点的数字值

Question

while(inFile.hasNext())
{
    String Desnation = inFile.next();

    if(givenLocation.equalsIgnoreCase(Desnation))
    {
        int num1 = inFile.nextLine();
        int num2 = inFile.nextLine();

        System.out.println("Yay!");
    }
}

它说它无法将字符串转换为 int，因此尝试事先解析它，但子字符串没有注册用户的输入。

Answer 1

您必须将字符串转换为整数:

try {
    int num1 = Integer.parseInt(inFile.nextLine());
    int num2 = Integer.parseInt(inFile.nextLine());
} catch(NumberFormatException e) {
    //handle exception, ex print some text
}

顺便说一句，为 Java naming convention说:

Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter. Internal words start with capital letters. Variable names should not start with underscore _ or dollar sign $ characters, even though both are allowed.
