Export text file and added names in the text field

Question

My code is when user type in the Name text filed, it will export as text file and record the Name. For example,

• I typed 1st time " James " in the Name text filed, it will appear " James " in the text file. I type second time " Agnes " , it appears " Agnes " in the text file. But It only appear one name in the text file.

  I want all the names appear whatever user type in the text filed. How do i modify my codes?

   try { new JTextField(); // create new file String path="C:\\\\export.txt"; File file = new File(path); // if file doesnt exists, then create it if (!file.exists()) { file.createNewFile(); } FileWriter fw = new FileWriter(file.getAbsoluteFile()); BufferedWriter bw = new BufferedWriter(fw); // write in file // bw.write(txtName.getText()); if (txtName.getText() ==null) { bw.write(txtName.getText()); bw.write('\\n'); System.out.print("1st Name:" +txtName.getText()); } else if (txtName.getText()!=null) { // bw.write('\\n'); bw.write(txtName.getText()); System.out.print("2nd Name:" +txtName.getText()); } // close connection bw.flush(); bw.close(); fw.close(); } catch(Exception e) { System.out.println(e); } 

Please advise.Thanks

Answer 1

写入文件时应使用追加模式，例如：

FileWriter fw = new FileWriter(file.getAbsoluteFile(), true);

Edit again:

            FileWriter fileWritter = new FileWriter(file.getName(),true);
            BufferedWriter bw = new BufferedWriter(fileWritter);

            if (txtName.getText()!=null){

            //this line edited 
               bw.write(txtName.getText()+"\n");               
              System.out.print("2nd Name:" +txtName.getText());
           }
