How to specify a text file in the command line... in Java(Netbeans)
I am trying to create a program that reads from two text file, and output will go one text file. I will use Netbeans which user set up two input file like Run> Set Project Cofiguratio> Customize> Main class, Argument. I do not want to specify the file by code like (../ srsc/ txtfile.txt) it should be like that. I already made my code the problem is the argument which should be file passing.

For example,
public class YourClass {
    public static void main(String[] args) {
        String fileName = args[0]; // would contain "textInput.txt"
        // work with fileName
    }
}

...........
java YourClass arg1 arg2 arg3
                       ^    ^    ^
index:                 0    1    2

Hi Buddy,

If I understood your question correctly, then the answer would be following:

in Ubuntu System, you just hav java compiler

to get java compiler in ubuntu run following command:

sudo apt-get install -y default-jdk

-------------*************-----------------

After installation

open terminal compile your program using following command:

javac YourClass.java  

// it will generate YourClass.class

Now:

java YourClass file1.txt file2.txt

-----------------------------------------------------------------------

if any queries please comment.
