某按钮的监视器方法actionPerformed()实现将文本区中的内容写入到文本文件myText.txt中。 public void actionPerformed(ActionEvent e) {

try {

int n = txtFld.getText().length();

byte buffer[]=new byte[n];

buffer=txtFid.getText().getBytes();

FileOutputStream wf=new ________________ ("myText.txt");

wf. write(buffer, 0,n); ________________;

}catch (IOException ioe){

txtFld.setText(ioe.toString());

}

}

}
