是控制台输入吗。为了方便类都写一个里面了。可以参考下
建立一个结果实体(标题、是否正确结果、选择的答案、正确答案)
建立一个题目list集合，用于存放题目(每个难度对应一个list)
建立一个结果list集合,用于存放作答后的信息
创建对应的题目对象,实体化实体，并且放入对应的list里面
根据选择对应的难度找到对应难度的list集合
然后遍历这个集合,依次显示每个题目的信息,并让用户作答，答完一个显示下一个题目，
获取用户选择的答案，用这个答案跟实体中的正确答案做比较
创建结果实体对象,将比较后的信息set到实体中。(标题、正确结果、选择的答案、正确答案)
将这个结果实体放入到结果list集合中；循环结束后遍历结果list集合显示就可以了。

粗略写了下，满足题目要求。楼主运行看看吧州信租。class Staff{
private String name
private int id
public Staff(String name,int id){
this.name = name
this.id =id
}
public void getInfo(){
System.out.println("name: " + name )
System.out.println("id: " + id)
}
}
public class Employee{
public static void main(String[] args){
Staff s1 = new Staff("王五"册兆,101)
Staff s2 = new Staff("张三坦燃",201)
s1.getInfo()
s2.getInfo()
}
}
