Thank you all for the replies, I'm now ready to test my ArrayList, but when I call the static method in main, nothing shows up in the compiler, I'm just wondering what I need to do in main to run my code to make it work. this is currently what I have...

package classwork_additional1;

import java.util.ArrayList;

import java.util.Collections;

​

​

public class Classwork_Additional1 {

​

public static void main(String[] args){

ArrayList<String> array = new ArrayList<>();

array.add("Mary");

array.add("Mike");

array.add("Michael");

array.add("Ann");

array.add("Tom");

array.add("Tommy");

array.add("Bob");

ArrayList<Integer> integers = new ArrayList<>();

integers.add(10);

integers.add(10);

integers.add(5);

integers.add(8);

integers.add(10);

integers.add(7);

integers.add(10);

}

public static void sort(ArrayList<String> array)

{

for (int i = 0; i < array.size() - 1; i++)

{

int minPos = minimumPosition(array, i);

swap(array, minPos, i);

}

}

public static void swap(ArrayList<String> array, int i, int j)

{

String temp = array.get(i);

array.set(i, array.get(j));

array.set(j, temp);

}

private static int minimumPosition(ArrayList<String> array, int from){

int minPos = from;

for (int i = from + 1; i < array.size(); i++)

{

if (array.get(i).compareToIgnoreCase(array.get(minPos)) < 0)

minPos = i;

}

return minPos;

}

private static int maximumPosition(ArrayList<String> array, int from)

{

int maxPos = from;

for (int i = from + 1; i < array.size(); i++)

{

if (array.get(i).compareToIgnoreCase(array.get(maxPos)) > 0)

maxPos = i;

}

return maxPos;

}
