???下面是我寫的view代碼，QUERYBYNAME根據(jù)姓名查看員工信息和?SEARCH查詢員工信息（根據(jù)姓名、科室）都無法達到預(yù)期。??QUERYBYNAME在輸入姓名后，程序無任何輸出。SEARCH方法只根據(jù)第二個條件，科室來查找。求解答。????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? ? public class View {
