The equals() method of java.util.AbstractSequentialList class is used to check if this AbstractSequentialList object is equal to the object passed as the parameter. This method returns a boolean value stating the same.
Syntax:
public boolean equals(Object o)
Parameters: This method takes the object o as a parameter to be compared for equality with this list.
Returns Value: This method returns true if the specified object is equal to this list.
Below are the examples to illustrate the equals() method.
Example 1:
// Java program to demonstrate equals()// method of AbstractSequentialList import java.util.*; public class GFG { public static void main(String[] argv) { // Creating object of AbstractSequentialList<String> AbstractSequentialList<String> arrlist1 = new LinkedList<String>(); // Populating arrlist1 arrlist1.add("A"); arrlist1.add("B"); arrlist1.add("C"); arrlist1.add("D"); arrlist1.add("E"); // print arrlist1 System.out.println("First AbstractSequentialListlist: " + arrlist1); // Creating another object of AbstractSequentialList<String> AbstractSequentialList<String> arrlist2 = new LinkedList<String>(); // Populating arrlist2 arrlist2.add("A"); arrlist2.add("B"); arrlist2.add("C"); arrlist2.add("D"); arrlist2.add("E"); // print arrlist2 System.out.println("Second AbstractSequentialList: " + arrlist2); // comparing first AbstractSequentialList to another // using equals() method boolean value = arrlist1.equals(arrlist2); // print the value System.out.println("Are both list equal: " + value); }} |
Output:
First AbstractSequentialListlist: [A, B, C, D, E] Second AbstractSequentialList: [A, B, C, D, E] Are both list equal: true
Example 2:
// Java program to demonstrate equals()// method of AbstractSequentialList import java.util.*; public class GFG1 { public static void main(String[] argv) { // Creating object of AbstractSequentialList AbstractSequentialList<Integer> arrlist1 = new LinkedList<Integer>(); // Populating arrlist1 arrlist1.add(10); arrlist1.add(20); arrlist1.add(30); arrlist1.add(40); arrlist1.add(50); // print arrlist1 System.out.println("First AbstractSequentialListlist: " + arrlist1); // Creating another object of AbstractSequentialList AbstractSequentialList<Integer> arrlist2 = new LinkedList<Integer>(); // Populating arrlist2 arrlist2.add(10); arrlist2.add(20); arrlist2.add(30); // print arrlist2 System.out.println("Second AbstractSequentialList: " + arrlist2); // comparing first AbstractSequentialList to another // using equals() method boolean value = arrlist1.equals(arrlist2); // print the value System.out.println("Are both list equal: " + value); }} |
Output:
First AbstractSequentialListlist: [10, 20, 30, 40, 50] Second AbstractSequentialList: [10, 20, 30] Are both list equal: false
