request.getParameter in a loop

I'm creating a matrix table with a lot of textboxes. The textboxes are named in a loop as follow:

<td><input type="text" name="<%=k%>-<%=i%>" size="6"></td>

When i passed the textbox values to the next page, I couldn't get the value of the textboxes (value = null).
Following is my script:

String[] result = new String[total];
String[] answer = new String[total];
int m=0;
int g=0;
for (int x=1; x <= counter; x++) {
for (int y=1; y <= counter; y++) {
result[m] = x + "-" + y;
answer[m] = request.getParameter("+result[m]+");
m++;

}
}

Anything wrong with the loop?

Some clarification: the double quotes around +result[m]+ makes it a string = +result[m]+, not the value you were trying to reference in the array.

request.getParameter(""+result[m]+"") would have work but obviously is unnecessary.

>>request.getParameter(""+result[m]+"")

should be request.getParameter(""+result[m])

The other String concatenation is unnecessary

sudhakar_koundinya

result[m] = x + "-" + y;
answer[m] = request.getParameter("+result[m]+");

I am seeing it as a String so simply

answer[m] = request.getParameter(result[m]) will work
