I want to add 00 before a number take for example 1 in JSP .like 1 to 001?

Question

I want to add 00 before a int example 1.How can i do that.I know that there is a way to do that using if condition and then concat() but i want a cleaner method for converting 1 to 001.

Create a static utility method in Java doing what you want. Register it as a JSP EL function in a JSP tag library. Invoke the JSP EL function from the JSP. http://docs.oracle.com/javaee/5/tutorial/doc/bnahq.html#bnaio — JB Nizet, Jun 27 '16 at 16:12

you can do it with javascript

example

function myFunction() {

   var num = 15;
      var n = num.toString();

    var str2 = "00";
    var res = n.concat(str2);
    document.getElementById("demo").innerHTML = res;
}

<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
