<br>  bj.show();
<br> }
<br>}
<br>
<br>
<br>
<br>这个程序 我要在最后输出有 交通津贴，，但是为什么总是没有。。
<br>
<br>程序可以运行。没错误
<br>
<br>
<br>请高手帮忙。。为什么最后一条 交通津贴不能显示

------------

将
<br> void main()
<br> {
<br>  super.show();
<br>  System.out.println("交通津贴："+transportAllowance);

更改为
<br> void show()
<br> {
<br>  super.show();
<br>  System.out.println("交通津贴："+transportAllowance);
