cast string to int java android

Question

How can I convert a String to an int in Java?

My String contains only numbers and I want to return the number it represents.

For example, given the string "1234" the result should be the number 1234

 String Availability = json.getString("Availability");before parsing value ="4" 
 int x = Integer.parseInt(Availability);here after parsing it gives me 2 i don't know why

What's wrong with what you posted? `json.getInt` is probably better (but probably does the same thing internally). — Elliott Frisch, Jan 23 '17 at 12:09
if i have number 4 Availability after parsing give me number 1 — hashim, Jan 23 '17 at 12:11
did you try to debug the value of `Availability` (please follow the naming convention, it should be `availability`. — SomeJavaGuy, Jan 23 '17 at 12:12
`Integer.parseInt()` is very strict. If it returns 1, it means your string is "1". — Steve Smith, Jan 23 '17 at 12:16
Sorry , `Integer.parseInt()` returns 2 if the `Availability` = "4" — hashim, Jan 23 '17 at 12:21
Provide a [mcve] without the JSON part (if `String availability` really contains "4" of couse). Since this parse should work, I suspect the problem come from your JSON. — AxelH, Jan 23 '17 at 12:22

You can use the foll function Integer.valueOf here is an example

public static void main(String args[]){
    int num = Integer.valueOf("22");
    num+=2;
    System.out.println(num); // output 24
}
