I have a bean , so in my doPost
I have List<applicationForm> allFound = new ArrayList<applicationForm>();
allFound=getStudent(conn, university_ID, currentRow);in my method I have
private  List<applicationForm> getStudent(Connection conn, String university_ID,  Integer CurrentRow)
    throws Exception {   
     try {
        conn =connectionPool.getConnection();      
          stmt = conn.createStatement(
              ResultSet.TYPE_SCROLL_INSENSITIVE,
              ResultSet.CONCUR_READ_ONLY);
         totalFamilyIncome="";
String  Sql="SELECT * FROM student as s, student_financial_info as f where s.student_id=f.student_id and   s.student_id='"+university_ID+ "'";
          rs = stmt.executeQuery(Sql);              
    connectionPool.returnConnection(conn);  
    allFound.clear(); //clean the session
    rowCount=0;
    while(rs.next()){   
  applicationForm myselect= new applicationForm();

  allFound.add(myselect);
return allFound;
I want to return total rowcount out of my getStudent(conn, university_ID, currentRow);
be use late by doPost, How can i do that

Answer 1

No need to count rows, the container List<applicationForm> comes with a function called size() that returns how many rows it contains.
Example:
List<applicationForm> x1 = getStudent(conn, university_ID, CurrentRow);
System.out.println("number of rows"+x1.size());
Additional Minor point:
You dont need to put single quotes around university_ID if its an integer. You do if its a string.
s.student_id='"+university_ID+ "'"
