如何从Java中的文件夹命名文件？

Question

I have a file named InputFile.txt in a resources folder. My project structure is like this:

• VirtualMemory
  • src
    • resources
      • InputFile.txt
    • VirtualMemory
      • VirtualMemory.java

And I am trying to access the InputFile.txt in VirtualMemory.java class by like this:

String filename = ("./src/resources/InputFile.txt");
File file = new File(filename); 

But the file is not being found. How to resolve this problem?

Answer 1

Below code will help load a properties file from any where in the classpath.

ClassLoader cl = ClassLoader.getSystemClassLoader();
    if (cl != null) {
        URL url = cl.getResource(CONF_PROPERTIES);
        if (url == null) {
            url = cl.getResource("/" + CONF_PROPERTIES);
        }
        if (url != null) {
            try {
                InputStream in = url.openStream();
                props = new Properties();
                props.load(in);
            } catch (IOException e) {
                // Log the exception
            } finally {
               // close opened resources
            }

        }
    }
