The equals() method of AbstractList class in Java
The equals() method of the AbstractList class is used to compare the specified object with this list for equality. The value TRUE is returned if both the lists are same i.e the same size and elements.
The syntax is as follows
public boolean equals(Object ob)
Here, ob is the object is to be compared for equality. To work with the AbstractList class, import the following package
import java.util.AbstractList;
The following is an example to implement equals() method of the AbstractlList class in Java
Example
import java.util.ArrayList;
import java.util.AbstractList;
public class Demo {
public static void main(String[] args) {
AbstractList<Integer> myList = new ArrayList<Integer>();
myList.add(75);
myList.add(100);
myList.add(150);
myList.add(200);
myList.add(250);
myList.add(300);
myList.add(350);
myList.add(400);
System.out.println("Elements in the AbstractList = " + myList);
AbstractList<Integer> myList2 = new ArrayList<Integer>();
myList2.add(75);
myList2.add(100);
myList2.add(150);
myList2.add(200);
myList2.add(250);
myList2.add(300);
myList2.add(350);
myList2.add(400);
System.out.println("Elements in the AbstractList2 = " + myList2);
System.out.println("Are both the lists same? = " + myList.equals(myList2));
}
}Output
Elements in the AbstractList = [75, 100, 150, 200, 250, 300, 350, 400] Elements in the AbstractList2 = [75, 100, 150, 200, 250, 300, 350, 400] Are both the lists same? = true
