本人在做练习时遇到一个问题

Question

问题在下面
public class A {

DBconn conn = new DBconn();
public Pat_Visit demo1(String PATIENT_ID){
Pat_Visit visit = new Pat_Visit();
String strSQL="select NAME,DEPT_ADMISSION from INFO where ID=?";

ResultSet rs = conn.execQuery(strSQL,new Object[] {PATIENT_ID});
try {
while (rs.next()) {
visit.setNAME(rs.getString(1));
visit.setDEPT_ADMISSION_TO(rs.getString(2));
conn.closeConn();
return visit;
}

} catch (SQLException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
conn.closeConn();
return null;
}
conn.closeConn();
return null;
}


public Dept_Dict demo2(){
    如何在这个方法里如何得到demo1方法里的visit.setDEPT_ADMISSON_TO的数据
         
}
}

Answer 1

[code="java"]
public class A {

DBconn conn = new DBconn();
public Pat_Visit demo1(String PATIENT_ID){
Pat_Visit visit = new Pat_Visit();
String strSQL="select NAME,DEPT_ADMISSION from INFO where ID=?";

ResultSet rs = conn.execQuery(strSQL,new Object[] {PATIENT_ID});
try {
while (rs.next()) {
visit.setNAME(rs.getString(1));
visit.setDEPT_ADMISSION_TO(rs.getString(2));
conn.closeConn();
return visit;
}

} catch (SQLException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
conn.closeConn();
return null;
}
conn.closeConn();
return null;
}

public Dept_Dict demo2(){
//调用demo1就行了嘛
String PATIENT_ID="要传递的id";
Pat_Visit pv = Pat_Visit demo1(PATIENT_ID);
pv.getDEPT_ADMISSION_TO

}
}
