> Hi Friends, > I have a problem of removing lines of text from a file. I got the line numbers which i have to remove but I am not sure how would i remove them. > Can somebody tell me what is the easiest way to do this? > Thanks > --Sam This may not be the easiest way, but Here's an algorithm I could suggest I. read each line of your file into a Vector of String objects. (Each line being an element in the Vector). II. call Vector.removeElementAt(index) for each line that you want to remove. III. At this point you will have a Vector of Strings containing only the data that you want in the file IV. Find some way to write each element of the vector back to the original file.
