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
