import java.util.ArrayList;
public class RemoveMin
{
public static void main(String[] args)
{
ArrayList<Integer> a = new ArrayList<Integer>();
// Add some integers to the array list
a.add(14); a.add(29); a.add(19); a.add(3);
a.add(15); a.add(62); a.add(18); a.add(97);
a.add(44); a.add(31); a.add(51); a.add(78);
// Print the array list - Note the use of the size() method and the get() method
for (int i = 0; i < a.size(); i++)
{
System.out.print(a.get(i) + " ");
}
System.out.println();
//Remove the minimum element from ArrayList a
removeMin(a);
// Print the array list again
for (int i = 0; i < a.size(); i++)
{
System.out.print(a.get(i) + " ");
}
System.out.println();
// Trick: You can also print the entire array by calling the toString() method
System.out.println(a.toString());
}
//-----------Start below here. To do: approximate lines of code = 8
// Write the static method removeMin with the correct parameter and return type
// See how removeMin is called above. HINT: google the ArrayList class and look at the
// remove method. HINT: // Find the minimum value first then remove it from the arraylist
