How would I declare the variable numbers as global? I want to be able to access the same variable from any method so that the value of the variable is the same.

Code:

import TerminalIO.KeyboardReader;
public class SortAndDestroy{
public static void main (String[] args){
int[] numbers = {42,37,5,33,6};
KeyboardReader reader = new KeyboardReader();
int choice;
for(int i = 0; i < Names.numbers.length; i++){
System.out.print(numbers[i] + " ");
}
choice = reader.readInt("\nSelection[1] or Bubble[2] Sort? ");
if (choice == 1)
selectionSort(numbers);
else if (choice == 2)
bubbleSort(numbers);
else
System.out.println("That is not a choice.");
}
public static void selectionSort(int[] numbers){
for(int i = 0; i < numbers.length; i++){
int minIndex = findMinimum(numbers, i);
if(minIndex != 1)
swap(numbers, i, minIndex);
System.out.print(numbers[i] + " ");
}
}
public static int findMinimum(int[] numbers, int first){
int minIndex = first;
for(int i = first + 1; i < numbers.length; i++)
if(numbers[i] < numbers[minIndex])
minIndex = i;
return minIndex;
}
public static void swap(int[] numbers, int x, int y){
int temp = numbers[x];
numbers[x] = numbers[y];
numbers[y] = temp;
}
public static void bubbleSort(int[] numbers){
int k = 0;
boolean exchangeMade = true;
while((k < numbers.length - 1) && exchangeMade){
exchangeMade = false;
k++;
for(int j = 0; j < numbers.length - k; j++)
if(numbers[j] > numbers[j + 1]){
swap(numbers,j,j + 1);
exchangeMade = true;
}
}
}
}
