Struts2: display int in JSP
Hi,
In my action, I have several variables of type int. When the variable
is not initialized, it's displayed as 0 in the JSP. I would like
un-initialized variable of type int to be display as blank/empty. What
is the best way to accomplish this? Thanks.
Public class XXAction extends ActionSupport
{
private int age;
private String name = new String("xyz");
private String email;
//getters & setters
}
JSP page would display:
Name: xyz
Email:
Age: 0

Please remember that because of java's autboxing, you shouldn't have
much problems (other than the cases when you are expecting zero). So
changing the type (from int to Integer) is really not a dramatic change.

RE: Struts2: display int in JSP
Posted by Jishnu Viswanath <ji...@tavant.com>.
Its not because of struts, int can not contain null, so nearest possible
brother is 0 so they put 0.
Ok, if you still want to use int, then put getter setter as String and
parse the input and output to integer and string.
int age = -1;
public String getAge(){
if(age<0)
return null;
else
return ""+age;
}
public String setAge(String age){
if(age == null)
this.age = 0
else
this.age = Integer.parseInt(age);
}
I think this solves your change of data type solves,
By the way one lesson I learned from experience was never use int,
float, boolean etc instead use Integer Float and Boolean etc.
