I want To append Some data in the File at specific location With the java Code

Question

I want to append some data in a file the java code.

My file contains the following data:

#JSGF V1.0;

/**
 * JSGF Grammar for Hello World example
 */

grammar hello;

public <greet> = (ANKIT)|(BHAVIK)|(MONIL)|(JAY)|(HIREN)|(KRUTIKA)|(RIKIN)|(YAGNESH)|(KRISHNA);

and I want that whenever I append file that data come before the ; charachter

So if I add JAYA then it appends like following :

public <greet> = (ANKIT)|(BHAVIK)|(MONIL)|(JAY)|(HIREN)|(KRUTIKA)|(RIKIN)|(YAGNESH)|(KRISHNA)|(JAYA);

Please give me some proper suggession or sample code for this.

i had Done like this to achive this kind of stuff as follows..

try { File f = new File("E:\NEw_Workspace\Voice_recognition_modify\src\edu\cmu\sphinx\demo\helloworld\hello.gram"); RandomAccessFile raf = new RandomAccessFile(f, "rw");

                    // Read a character
                   // char ch = raf.readChar();

                    // Seek to end of file
                    raf.seek((f.length())-1);

                    // Append to the end
                    raf.writeChars("|(ASHISH);");
                    raf.close();
                } catch (IOException e) {
                }

I had Done that With the Following Code ..Got success.

               File f = new File("E:\\NEw_Workspace\\Voice_recognition_modify\\src\\edu\\cmu\\sphinx\\demo\\helloworld\\hello.gram");
                    RandomAccessFile raf = new RandomAccessFile(f, "rw");

                    // Read a character
                   // char ch = raf.readChar();

                    // Seek to end of file
                    raf.seek((f.length())-1);

                    // Append to the end
                    raf.write(("|(KARAN);").getBytes());

                    raf.close();
                } catch (IOException e) {
                }
