Inserting text in middle using RandomAccessFile removes some text after that

Question

    RandomAccessFile file = new RandomAccessFile(\"D:/mahtew.txt\", \"rw\");
    System.out.println(file.getFilePointe         


        

Answer 1

If replaced string is too long, the strings after the line matched with input will be replaced. It seems you have to read file, modify it and write back to old or new file. Of course, you have options to use multi-threading programming and Java 7's new IO features to improve performance.
