To reverse an array list
import java.util.ArrayList;
import java.util.Collections;
public class Main
{
public static void main(String[] args)
{
ArrayList arrayList = new ArrayList();
arrayList.add("A");
arrayList.add("B");
arrayList.add("C");
arrayList.add("D");
arrayList.add("E");
System.out.println("Before Reverse Order: " + arrayList);
Collections.reverse(arrayList);
System.out.println("After Reverse Order: " + arrayList);
}
}
Result:
Before Reverse Order: [A, B, C, D, E]
After Reverse Order: [E, D, C, B, A]
