java - Using getParameterValues and Arrays -
so getting parameters page, , putting them array, taking items in array , running substring
method on them:
string[] edit = request.getparametervalues("editid"); // system.out.println(edit); string editdel = ""; if (edit != null) { (int = 0; < edit.length; ++i) { string lf = edit[i]; editdel = lf.substring(0, lf.length() - 2); } } else { editdel = "0"; } // system.out.println(editdel);
so example if pass params 3lf
, 12lf
previous page, system prints [ljava.lang.string;@520
variable edit
, , prints 12
variable editdel
. need store editdel
in array, because should getting both 12
, 3
editdel
variable
put editdel print statement inside loop
(int = 0; < edit.length; ++i) { string lf = edit[i]; editdel = lf.substring(0, lf.length() - 2); system.out.println(editdel); } } else { editdel = "0"; }
