巧妙使用数组，内部匿名类改变外部类final对象值

final boolean confirmFlag[] = new boolean[]{false}; SwingUtilities.invokeLater(new Runnable() {@Overridepublic void run() {Object[] options = { "确定", "取消" };int response = JOptionPane.showOptionDialog(PosMain.this, mergeMsg.toString(), "提示",JOptionPane.YES_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[1]);if (response == 0) confirmFlag[0] = true;}});
