Dear Ranchers,
I'm doing a project in JSP. In this I'm passinga value string value status which is equal to 0 and later will convert that to a integer value x. When i put the condition if(x==0) then it is not printing the function.

Please help me to sort out this problem..



Please help me..

Thanks in advance

Your code is wrong.

You first tell me is it possible to convert String Variable to Integer.

You had compared your status variable to "all".
Now as for example what if your status value is "all".
It will come to Integer.parse("all") and will generate exception.

You can check it using

Hi Aravind,

in the beginning of your code there is an if-else statement.



If x isn't initialized (to 0) before the if-else statement and the string
status doesn't equal "all" x wont have the value 0. If it doesn't have the
value 0 the "program" wont enter the if(x==0) block of your code.

Does this make sence?
