java - 无法在 Java 上输入所需的名称

Question

我有一个文本文件:

Filename: apple.jpg
Name: Apple
Brief: Apple is a fruit

Filename: orange.jpg
Name: Orange
Brief: Orange is also a fruit

Filename: tomato.jpg
Name: Tomato
Brief: Tomato is not a fruit, it's a vegetable

我有一个代码:

public class Test
{
public static void main(String[] args) throws IOException{
    Scanner reader = new Scanner(new File("C:/textLocation.txt"));

    String filename = "";
    String name = "";
    String brief = "";

    String line = "";
    while (reader.hasNextLine()){
        line = reader.nextLine();

        if (line.startsWith("Filename:") && (line.contains("apple"))){
            filename = line.substring(10, line.length());
        } else if (line.startsWith("Name:")){
            name = line.substring(6, line.length());
        } else if (line.startsWith("Brief:")){
            brief = line.substring(7, line.length());
        }
    }
    System.out.println(filename);
    System.out.println(name);
    System.out.println(brief);
}
}

我遇到的问题是当我设置 apple 时，它​​使 Filename 为 apple.jpg，这是正确的，但 Name 和 Brief 是番茄的。我该如何纠正这个问题？ 提前谢谢你。

public class Test {
    public static void main(String[] args) throws IOException{
        Scanner reader = new Scanner(new File("C:/textLocation.txt"));

        String filename = "";
        String name = "";
        String brief = "";
        boolean lookingForName = false;
        boolean lookingForBrief = false;

        String line = "";
        while (reader.hasNextLine()){
            line = reader.nextLine();

            if (line.startsWith("Filename:") && (line.contains("apple"))){
                filename = line.substring(10, line.length());
                lookingForName = true;
                lookingForBrief = true;
            } else if (line.startsWith("Name:") && lookingForName){
                name = line.substring(6, line.length());
                lookingForName = false;
            } else if (line.startsWith("Brief:") && lookingForBrief){
                brief = line.substring(7, line.length());
                lookingForBrief = false;
            }
        }
        System.out.println(filename);
        System.out.println(name);
        System.out.println(brief);
    }

}
