compare two arraylist in java code example

Example 1: how to compare two arraylists are equal in java

public class ArrayListExample 
{
    public static void main(String[] args) 
    {
        ArrayList<String> listOne = new ArrayList<>(Arrays.asList("a", "b", "c", "d", "f"));
         
        ArrayList<String> listTwo = new ArrayList<>(Arrays.asList("a", "b", "c", "d", "e"));
         
        Collections.sort(listOne);
        Collections.sort(listTwo);
         
        //Compare unequal lists example
         
        boolean isEqual = listOne.equals(listTwo);      //false
        System.out.println(isEqual);
         
        //Compare equals lists example
         
        ArrayList<String> listThree = new ArrayList<>(Arrays.asList("a", "b", "c", "d", "f"));
         
        isEqual = listOne.equals(listThree);      //true
        System.out.println(isEqual);
    }
}

Example 2: compare to arraylist java

import java.util.*;  
public class ComapreArraylistExample1  
{  
	public static void main(String args[])  
    {  
      //first array list  
      ArrayList<String> firstList=new ArrayList<String>();  
      //adds elements to the arraylist  
      firstList.add("Apple");  
      firstList.add("Pears");  
      firstList.add("Guava");  
      firstList.add("Mango");
      //second array list
      List<String> secondList=new ArrayList<String>();  
      //adds elements to the arraylist  
      secondList.add("Apple");  
      secondList.add("Pears");  
      secondList.add("Guava");  
      secondList.add("Mango");  
      //comparing both lists  
      boolean boolval = firstList.equals(secondList); 
      //returns true because lists are equal  
  	}  
}
