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
