Java splitting input

Question

i'm trying to write a simple code for my project if user types walk 10 i need to use "walk" command in my walk(distance) method as distance = 10 i have something like that ``` while (!quit) { Scanner in = new Scanner(System.in); String input = in.nextLine(); // if (walk x is typed) { walk(x); } } ``` i'm using java.util.scanner and another problem is that my method walk(int x) uses int so i need to convert String input to int i searched the web for a while but couldnt find what i'm looking for (or i didnt understand it) so anyway i'd appreciate if you can help me thanks Thanks a lot for all the answers my initial problem is fixed but now i have another problem when i type just "walk" it gets array out of bounds exception of course because it tries to convert null to an int (not possible) i tried this and checked online ``` try { Integer.parseInt(splitStrings[1]); } catch(NumberFormatException e) { System.out.println("error: " + e); } ``` still no help (i'm not good with try/catches) s…

Accepted Answer

Try using the split() method on a string. It will return an array of Strings. For example

```
String s = 'walk 10';
String[] splitStrings = s.split(" ")
```

Now, to access 10, you can do this:

```
String distanceToWalk = splitStrings[1]
```

To convert it to an int, use the parseInt() method on Integer

```
Integer.parseInt(distanceToWalk);
```
