Java 在Netbeans IDE 8.1中使用命令行参数

我试图让我的Java程序工作，但它给了我以下错误：

run:
Can't find file scores.txt
java.io.FileNotFoundException: scores.txt (The system cannot find the file specified)
at java.io.FileInputStream.open0(Native Method)
usage: java ScoresReader sourceFile destFile

    cern.list.IntArrayList
at Scores.scoreseader.ScoresReader.main(ScoresReader.java:262)
BUILD SUCCESSFUL (total time: 2 seconds)

当我运行项目或文件时，它给了我上述错误。以下是一段简短的代码片段：

public class ScoresReader implements Serializable
   {
    private static final long serialVersionUID = 7526472295622776147L;
    public OpenIntIntHashMap Scores;

    /**
    * Default constructor. Initializes hashtables. 
    */
    public ScoresReader()
       {
        Scores = new OpenIntIntHashMap();
        ..
        ..
       }
    /**
    * Reads a text file
    */
    public void readData(String fileName)
       {
        //Reads from an input text file in the form of:
        //score_id, user_id, score
        //and stores this data in the hashtables. 
       }

    /**
    * Serializes a ScoresReader object so that it can be read back later. 
    */
    public static void serialize(String fileName, ScoresReader obj)
       {
        //serialize the score objects
        ..
       }

    public static void main(String args[])
       {
        ScoresReader reader = new ScoresReader();
        String sourceFile = null;
        String destFile = null;
        try
           {
            sourceFile = args[0];
            destFile = args[1];
            reader.readData(sourceFile);
            reader.sortScores();
            serialize(destFile, reader);
             ..
             ..
           }
       catch(Exception e)
           {
            System.out.println("usage: java ScoresReader sourceFile destFile");
            e.printStackTrace();
           }
       }//end main
    }//end class ScoresReader

有人能告诉我为什么找不到文件吗

提前谢谢

从菜单栏打开文件菜单

选择项目属性

转到“跑步”选项卡

在参数字段中插入所需的参数

按Run正常运行项目

在Netbeans中，您是否使用默认包来存储类文件。在这种情况下，可以将stores.txt存储在同一个文件中。如果你的类文件在'src'文件夹中，那么txt文件应该在上面的一个文件夹中，即../src中谢谢你的建议。是的，我正在使用默认包和我的类文件，包括默认包中的其他辅助文件。txt文件应该在上面一个文件夹是什么意思？我在IDE中查看了src文件夹，上面是项目文件夹-这就是你的意思吗？是否将txt文件放在项目文件夹中？谢谢好的——将txt文件放在src文件夹上方一个文件夹似乎可以消除“找不到文件”错误。但是它给了我一个不同的错误，它是：参见下面的用法：java ScoresReader sourceFile destFile java.lang.NumberFormatException:对于输入字符串：在java.lang.NumberFormatException.forInputStringNumberFormatException.java:65在java.lang.Integer.ParsinInteger.java:569在java:118 at java.lang.Short.parseShortShort.java:144 atProjectScore.scoresreader.scoresreader.readDataScoresReader.java:77 at ProjectScores.scoresreader.scoresreader.mainScoresReader.java:260构建成功总时间：0秒我建议您提供一个从文件读取对象的快速教程
