Java – create a runnable jar that contains external files

I want to build a running jar. Jar in Java I need to include some files in the jar so that when I execute the jar, these files will be automatically read from the Java class Therefore, I created a folder in the project and referenced these files from the project I created jar files after some tutorials, but I can't include these external files in my jar files Let me talk about using external files to create runnable jars

My file is

Test
|
|
-------src
|        |
|        default package
|                      |
|                      |
|                      test1.java
|
 -------FileFOlder
|              |
|              | 
|              abc.txt

I'm at test1 Access ABC. Java class txt. My code is

public class test1 {


public static void main(String[] args) throws IOException {


    char [] read = new char[20];
    String path = new File(".").getCanonicalPath();
    path = path+"\\Newfolder\\abc.txt";
    System.out.println(path);
    File nF = new File(path);
    FileReader fR = new FileReader(nF);
    fR.read(read);
    for(char c : read){
        System.out.print(c);
    }
    fR.close();
    System.out.println(" Hi..This is test program ");
}

}

When I use the eclipse export option to create an executable jar, I cannot see the filefolder directory in the jar Please give me some information about this

Solution

This is what you should do:

Put the file back into your jar file Use class Getresourceasstream() to read it instead of file and FileReader How to really read text file from classpath in Java
