When I read up the contents in a text file ... How can I remove certain char that I dont want it to be display when I print out the contents from the text file ?

e.g. the content in the file is
Name : XXXXXX
Age : 19

I want to remove the "Name :" and "Age :" , so that XXXXXX and 19 will be display ..

Like so:

        String line1 = "Name : XXXXXX";

        String line2 = "Age : 19";


        line1 = line1.replaceAll("^Name : ", "");

        line2 = line2.replaceAll("^Age : ", "");

        System.out.println(line1);

        System.out.println(line2);

Or:

String line3 = "Birthdate : 19/09/1999";

line3 = line3.substring(line3.indexOf(":")+2);

You do it line by line, using wim DC's suggestion.

A loop, home slice.

ArrayList<String> strs = new ArrayList<String>();

for (String extractValueFrom : userInputLines)

{

    strs.add(extractValueFrom.substring(extractValueFrom.indexOf(":") + 2));

}

Now the extracted values are in the ArrayList strs. You can display those using an equivalent loop with System.out.println(strs.get(i)).

sorry I dont get what you are tryong to say ...
here's my code :

FileInputStream file = null;

        try {

            file = new FileInputStream("C:\\Users\\Johnny\\Downloads\\Desktop\\TheFile.csv");

            BufferedReader br = new BufferedReader(new InputStreamReader(file));

            String strLine = null;


            while ((strLine = br.readLine()) != null) {

                String results = strLine.replaceAll(".mol2", "").replace(",", "");

                      

                if (strLine.trim().contains("Name")) {

                    continue;

                }

               

                System.out.println(results);

            }

        } catch (IOException e) {

            e.printStackTrace(); // Alternate way to print the entire error


        } finally {

            // Close file

            try {

                if (file != null) {

                    file.close();

                }

            } catch (IOException e) {

                e.printStackTrace();

            }


        }

    }

all files names all contain a .mol2 extension .. How can I modify it with your code ?
Sorry I anot very good in java :(

Just add

results = results.substring(results.indexOf(":") + 2)

in the while loop I guess.
