已知类型的声明： public class Employee extends Object{ int id; String name; } 请将下面语句补充完整， Object o1 = new Employee(); Object o2 = new Employee(); Employee e1 = ( )o1; Employee e2 = ( )o2; e1.name = "zhangsan"; e2.name = "lisi"; if( ){ System.out.println("两位员工姓名相同！"); }

Employee e1 = (Employee) o1;
Employee e2 = (Employee) o2;
if(e1.name.equals(e2.name)){
System.out.println("两位员工姓名相同！");
}
