Question

I need a way to delete a line, im using this to write on the file:

    FileWriter insert = new FileWriter(file, true);  
    PrintWriter out = new PrintWriter(insert);  
    out.println("1. Mario"); 

I made a thing that reads line by line but i’ve no idea how to delete the string that returns, is that even possible?

Answer 1

While you’re reading in the lines of text write then lines you want to keep to a StringBuffer or StringBuilder then write the contents of the buffer/builder back to the file. Is there any specific reason that you’re opening up the file for appending when you’re wanting to remove lines of text from the file or am I missing something?
