It is actually very simple all you ne4ed to do is just add append option.
I hope you got this.Code:new FileOutputStream(f, true /* append */);
Append To File
You can use the class FileWriter and BufferedWriter to append the data to a file.
BufferedWriter
The BufferWriter class is used to write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.
Try This:
Code:import java.io.*; class FileWrite { public static void main(String args[]) { try{ // Create file FileWriter fstream = new FileWriter("out.txt",true); BufferedWriter out = new BufferedWriter(fstream); out.write("Hello Java"); //Close the output stream out.close(); }catch (Exception e){//Catch exception if any System.err.println("Error: " + e.getMessage()); } } }
java append text to file
Code:try { BufferedWriter out = new BufferedWriter(new FileWriter("filename", true)); out.write("aString"); out.close(); } catch (IOException e) {}
