看到了，你这有三个错误，第一个是你的private double saalary;  这个变量多写了一个a;
  for(Employee e:staff)
    System.out.println("name"=+e.getName()+",salary="+e.getSalary());  // name 这里的= 号写在了外面应该是"name = "+e.getName()+",
public double getSalary()
{
  return salary();    //这里你写错了，salary 是属性，不是方法;  
}
这此错误都是书写错误啊，你应该自己解决的哦。



  

不知道你提示什么错误

1 你 System.out.println("name"=+e.getName()+",salary="+e.getSalary());里的=号要放括号里面去
2 private double saalary; saalary是不是写错了?
3 如果提示有符号： 变量 Arrays
位置： 类 Test
  Arrays.sort(xxx);  

类型的错误,则是没有导入相应的包



4 还有return salary; 是变量,不是方法  (刚才忘记写上了。重新编辑了一下)
