ファイルの値を変更するJava

Question

ファイル内の値を変更したいUtilizadores.txt デフォルト値はzeroですが、ボタンをクリックすると値が10に変更され、新しい値が変更されるたびに変更されます値が+10 になる問題は、（10/20/30 ...）と表示されるスペースが空白になるようにしようとするときです

PS：ファイルの行だけが変更されます。特定のID（私のユーザーのID）

private void ConfirmarActionPerformed(java.awt.event.ActionEvent evt) {  
    String filePath = "Reservas.txt"; 
    File file = new File(filePath); 
    try {

     bw1.write(this.id+ "-" + cbxrestaurante.getSelectedItem().toString() + "-" + Dia.getText() + "-" + Hora.getText() + "-" + Lugares.getText());

     bw1.close(); 
     fw1.close();

Answer 1

はStringにあなたの整数を変換しようとしている。 bw.write(String.valueOf(getPontos[i])); 代わりに bw.write(getPontos[i]);
