Well, without your explaining how each String in the array should become an int, we can't really answer. Are they Strings like "1", "2", "3"? Are they Strings like "one", "two", "three"? Are they "red", "blue", "green" and the ints should be indexes into some list, somewhere? Without our knowing how each single String should be converted to an int, there's no way to know how to convert the whole array.

You can convert this as:

code:


String [] chckbox = request.getParameterValues("jspchckbox");
int[] value = new int[chckbox.length];
for(int i=0; i<chckbox.length; i++)
value[i] = Integer.parseInt(chckbox[i]);



This is what I did, but it is only pick the first item, i check 4 checkboxes on the jsp, so the value should be 1,2,3,4 (actual value)

[code]
String [] chckbox = request.getParameterValues("jspchckbox");
int[] value = new int[chckbox.length];
for(int i=0; i<chckbox.length; i++)
{
value[i] = Integer.parseInt(chckbox[i]);
this.getValues(value); ??? // i invoke the method i had and the value[] array, but return only 1 value from the chckbox instead of 1,2,3,4..
}

Any ideas? Thank you again

"Ajay S",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!
