Can someone help me with Java Programming!!!!?
This is a very remedial problem as I am in a basic java course, but I kinda need some help on it. when I call the sort function I keep getting a message that's saying that the variable can't be found. what can i do to make this work? and please keep it simple because this is basic after all.
public class Sort
{
private static int numbers = 0;
public static void main(String[] args)
{
int[] numbers = {20,10,40,30};
numbers.sort();
}
}

This really confused me for a while, just finishing my first year in an Computer Science degree I'm also somewhat of a Java beginner :)
But I found what the problem is!
'sort' is not a method of all arrays, its a method of the 'Arrays' class. This is a separate class you need to import, you'd end up with something like this:
import java.util.Arrays;
public class Sort {
public static void main(String[] args)
{
Sort sortObject = new Sort();
}
public Sort(){
int[] numbers = {20,10,40,30};
Arrays.sort(numbers);
}
}
I also moved it into the constructor of the class instead of the main method but that's just semantics. Hope that helps :)
