use java 1.4 instead of java 1.5 for generics

[sai rama krishna]

I have a hashmap which has username and password information.

Map mapDetail = new HashMap(); 
mapDetail.put("username",username); 
mapDetail.put("password",password); 
HashMap is embedded in a arraylist like below 
List missingList = new ArrayList(); 
missingList.add(mapDetail); 

I am reading the username and password information to send it to one other method as follows.

private static void checkDatabase(Vector dataHolder) {
		String username="";
		String password="";
		PreparedStatement pstmt = null;	
		List<HashMap<String,String>> missingList =
                        new ArrayList<HashMap<String,String>>();
		System.out.println("dataHolder.size()--->"+dataHolder.size());

		for (int i=1;i<dataHolder.size(); i++){
			Vector cellStoreVector=(Vector)dataHolder.elementAt(i);
			int usernameIndex = new Integer(genericImporterProp.getString(
                            "username.index")).intValue();
			HSSFCell myCell = (HSSFCell)cellStoreVector.elementAt(
                            usernameIndex);
			myCell.setCellType(myCell.CELL_TYPE_STRING);
			String stringCellValue = myCell.toString();
			username = stringCellValue;

			int passwordIndex = new Integer(genericImporterProp.getString(
                           "password.index")).intValue();
			myCell = (HSSFCell)cellStoreVector.elementAt(passwordIndex);
			myCell.setCellType(myCell.CELL_TYPE_STRING);
			stringCellValue = myCell.toString();
			//stringCellValue=stringCellValue.t
			password=stringCellValue;
			 // double aDouble = Double.parseDouble(stringCellValue);


			try{
				Class.forName("com.mysql.jdbc.Driver").newInstance();
				Connection con = DriverManager.getConnection(
                             "jdbc:mysql://localhost:3306/test","root", "root");
				Statement stmt = con.createStatement();


				String usernameColumn = genProp.getString("usernameColumn");
				String passwordColumn = genProp.getString("passwordColumn");
				ResultSet rs1 = stmt.executeQuery("select * from login where "  +
                          usernameColumn + "='"+username+"' and " +
                          passwordColumn + "='"+password+"'");


				boolean isExist = false;
				if (rs1!=null) {

					while (rs1.next()){
						isExist=true;
						String rec1 = rs1.getString(1);
						String rec2 = rs1.getString(2);
						System.out.println("rec1 is--"+rec1+"---rec2 is---"+rec2);
					}
				}

				if (!isExist) {
					HashMap<String,String> mapDetail =new HashMap<String,String>();
					mapDetail.put("username",username);
					mapDetail.put("password",password);




					for(HashMap<String,String> newMapDetail : missingList) {
						String myUseridToPass = newMapDetail.get("username");
						String myPasswordToPass = newMapDetail.get("password");
						System.out.println("myUseridToPass-->"+myUseridToPass);
						System.out.println("myPasswordToPass-->"+myPasswordToPass);
						
					}


					missingList.add(mapDetail);

				}


				//pstmt.close();
				con.close();
			}
			catch(Exception e){

				System.out.println("e-->"+e);
			}
		}

		System.out.println("Missing List : "+missingList);

		generateCsvFile("c://MissingList.csv", missingList); 
		sendErrorEmail("c://MissingList.csv");

	}

Challenge now I have is server is running on java 1.4 not java 1.5.
I need to modify my code to remove java 1.5 Generics and use java 1.4. How Can achieve it

>>>
List<HashMap<String,String>> missingList = new ArrayList<HashMap<String,String>>();


>>>
for(HashMap<String,String> newMapDetail : missingList) {
		String myUseridToPass = newMapDetail.get("username");
		String myPasswordToPass = newMapDetail.get("password");
		System.out.println("myUseridToPass-->"+myUseridToPass);
		System.out.println("myPasswordToPass-->"+myPasswordToPass);
}

Any ideas, suggestions, sample code, links, source code highly appreciated. Thanks in advance

What you need to do is called 'cross compilation.' The compiler can do this by passing the target command flag option when compiling the code. See: http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html. There are some notes on that page about cross compilation you should read.
