java - 来自命令行的 NetBeans Java 项目 : Working directory is System32

Question

如果我在 NetBeans 中运行 Java 程序并按照输出窗口中给出的信息从命令行运行:

To run this application from the command line without Ant, try:
java -jar "C:\Users\erdik\OneDrive\Documents\Computing Science Degree\Course Folder\Year 1\Programming 1\Assignment 2 - Year 2 Edit\assignment2\dist\assignment2.jar"

程序开始运行，但是当需要运行以下代码来打开 .txt 文件(我的“数据库”)时:

System.out.println("Loading database of stored transactions...");
try 
{ 
    file = new File("TransactionDetails.txt");
    inFile = new Scanner(file);
} 
// if the log couldn't be found in the default program location
catch (FileNotFoundException ex)    
{
    System.out.println(CustomMessages.FileNotFound() + 
            System.getProperty("user.dir"));  // display default directory
    System.out.println(CustomMessages.systemExit());
    System.exit(1);  // the program needs the log to function as intended
}

它找不到 .txt 文件，并将默认目录打印为 Windows System32 文件夹。如何按预期指定项目文件夹的位置？

Answer 1

您可以使用文件的绝对路径而不是相对路径。例如

file = new File("C:\Users\erdik\OneDrive\Documents\Computing Science Degree\Course Folder\Year 1\Programming 1\Assignment 2 - Year 2 Edit\assignment2\dist\TransactionDetails.txt");
inFile = new Scanner(file);
