Help! Check data in MS Excel file(JDBC-ODBC)

Question

Hi guys,
I wrote a program that can check data in MS Excel file.
User can input a sentence like "1->2" ,"1->3" (one determine one), then the program can find the data which violate the integrity constrains(functional dependency).For example, if we have the functional dependency "TSeq_gi->TSeq_accver", the program looks for two or more tuples with the same "TSeq_gi" value but the different "TSeq_accver" value in Excel file. These tuples violate the integrity constraint. But now,I can't figure out how to modify this program to multiple determine one. (like 1 3->5 or 1 3 4 5->7) . 1 3 ->5 means: look for 1 and 3 have same value but 5 different. I get stuck. Can some experts help me?
The code and Excel file are in below link. Download and play it! Thank you~~
Karen.

PS: You need to set up JDBC ODBC driver in MS windows "Administrative Tools" first. Data Souce name is Test .
Main logic class:
class MyActionListener implements ActionListener{
public void actionPerformed(ActionEvent e){
if (e.getActionCommand()=="SEARCH")
     try{
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     con1= DriverManager.getConnection("jdbc:odbc:Test");
     stmt2= con1.createStatement();
input1 = new String(pathTf.getText());     
     main_loop: while(true){
if (input1.equals("0")){     
          // break out of while(1)
          break main_loop;
     st= new StringTokenizer(input1," ,-=>");          
          while(st.hasMoreTokens()){
               // analyze the input stream.
               // Attention, the program didn't do the input value check.
               input1= st.nextToken();
               input2= st.nextToken();               
          query= "select "+ schema[Integer.parseInt(input1)-1]+ ","+ schema[Integer.parseInt(input2)-1]+ " from [Sheet1$]";     
          rs2= stmt2.executeQuery(query);     
          rowCounter= 0;
          list1.clear();
          list2.clear();
          list3.clear();
          while(rs2.next()){
               // increase the row counter
               rowCounter++;
               // initial the flag
               col1= rs2.getString(1);
               col2= rs2.getString(2);               
               // for the initalization
               if (list1.isEmpty()){
               list1.addElement(col1);
               list2.addElement(col2);
               row="Row 2";
               list3.addElement(row);     
               // compare weather exist dependance
               else
               for (int i=0;i<list1.size();i++){
                    // if col1 match with the first part of value in the list
                    if (((String)list1.get(i)).equals(col1)){
                         // The independence pair match
                         if (((String)list2.get(i)).equals(col2)){
                              break;
                         else
                              textArea.append("\n"+"Violate Integrity Constraints Found : "+" Row "+ (rowCounter+1)+ " not match with "+ list3.get(i)+".");
                              System.out.println("\n"+" Row "+ (rowCounter+1)+ " not match with "+ list3.get(i)+".");      
                              break;                    
                    // if col1 not match with any value, add a new record in list
                    else
                         list1.addElement(col1);
                         list2.addElement(col2);
                         row="Row "+ (rowCounter+1);
                         list3.addElement(row);
               }// end of for
               }//end of else
}//end of while
}//end of while(1): main_loop
     }catch(Exception ex){
     //System.err.println(ex);
