spring - JSP Catching Event from RadionButton -


i looking onchange listener radiobutton in jsp. using example: https://www.tutorialspoint.com/springmvc/springmvc_radiobutton.htm know how catch event of radiobutton on controller ??

there not exist default way in spring. why want this?

you use ajax call send data of selected button rest controller. similar pseudo-code.

    jquery(document).ready(function($) {       $("#your-buttons").change(function(event) {         event.preventdefault();         var data = formname.your-buttons.value;          $.ajax({             type : "post",             contenttype : "application/json",             url : "your/api/url",             data : json.stringify(data),             datatype : 'json',             success : function(data) {                 display(data);             },             error : function(e) {                 display(e);             }         });        });     });

then on rest controller have handle other event.

@requestmapping(value = "/your/api/url", method = requestmethod.post) public string whatever(.....) {     // ... }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
