"for" error in scriplet

Question

Here is my code
String[] del_val = new String[6];
     String[] exe_stmt = new String[6];
     String[] col_name = new String[6];
     String all_stmt;
     int count;
     col_name[0] = "projectID";
     col_name[1] = "stuID";
     col_name[2] = "JRSJ";
     col_name[3] = "TCSJ";
     col_name[4] = "BZ";
     col_name[5] = "Status";
     del_val[0] = %>${param.del_projectID}<%;
     del_val[1] = %>${param.del_stuID}<%;
     del_val[2] = %>${param.del_JRSJ}<%;
     del_val[3] = %>${param.del_TCSJ}<%;
     del_val[4] = %>${param.del_BZ}<%;
     del_val[5] = %>${param.del_Status}<%;
     for(int i=1;i<=6;i++){
          if(i != 6){
               for(int j=i+1;int<=6;j++){
                    if(del_val[j] != null){
                         count = count + 1;
          if(del_val[i] != null){
               if(count>0){
                    exe_stmt[i] = col_name[i] + "='" + del_value[i] + "'";
               }else{
                    exe_stmt[i] = col_name[i] + "='" + del_value[i] + "' AND ";
          }else{
               exe_stmt[i] = null;
but there is an error

another question is can I use AWT or SWING in JSP

Answer 1

Sure its JSP, hes just trying to use EL (the new Expression Language) in an absolutely HORRIBLE way.
Not to mention the use of scriptlets in a JSP - this looks more like it should be a servlet.
But anywayz:
user request.getParameter() calls rather than ${param.} in EL Mixing scriptlets and expressions is just asking for trouble.
del_val[0] = request.getParameter("del_projectID");
del_val[1] = request.getParameter("del_stuID");
The explicit line which is creating the problem: for(int j=i+1;int<=6;j++){
should be for(int j=i+1; j<=6; j++) - not int<=6.
Your loop should probably loop for values 0,1,2,3,4,5 - ie the array elements. not 1-6
for(int i=0; i<del_val.length; i++)
That fixes up at least some of the obvious problems...
Good luck,
