LinkedBlockingDeque equals() method in Java with Example
The equals() method of java.util.LinkedBlockingDeque class is used to compare the specified object with this LinkedBlockingDeque for equality. Returns true if and only if the specified object is also a LinkedBlockingDeque, both LinkedBlockingDeques have the same size, and all corresponding pairs of elements in the two LinkedBlockingDeques are equal. (Two elements e1 and e2 are equal if (e1==null ? e2==null : e1.equals(e2)).) In other words, two LinkedBlockingDeques are defined to be equal if they contain the same elements in the same order.
Syntax:
public boolean equals(Object o)
Parameters: This method takes the object o as a parameter to be compared for equality with this LinkedBlockingDeque.
Returns Value: This method returns true if the specified object is equal to this LinkedBlockingDeque.
Below examples illustrates the LinkedBlockingDeque.equals() method:
Program 1:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<Integer> LBD1
= new LinkedBlockingDeque<Integer>();
LBD1.add( 7855642 );
LBD1.add( 35658786 );
LBD1.add( 5278367 );
LBD1.add( 74381793 );
System.out.println( "Linked Blocking Deque 1: " + LBD1);
LinkedBlockingDeque<String> LBD2
= new LinkedBlockingDeque<String>();
LBD2.add( "1" );
LBD2.add( "2" );
LBD2.add( "3" );
LBD2.add( "4" );
System.out.println( "Linked Blocking Deque 2: " + LBD2);
System.out.println( "Are both Linked Blocking Deque equal: "
+ LBD1.equals(LBD2));
}
}
|
Output:
Linked Blocking Deque 1: [7855642, 35658786, 5278367, 74381793]
Linked Blocking Deque 2: [1, 2, 3, 4]
Are both Linked Blocking Deque equal: false
Program 2:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<String> LBD1
= new LinkedBlockingDeque<String>();
LBD1.add( "1" );
LBD1.add( "2" );
LBD1.add( "3" );
LBD1.add( "4" );
System.out.println( "Linked Blocking Deque 1: " + LBD1);
System.out.println( "Is LBD1 equal to LBD1: "
+ LBD1.equals(LBD1));
}
}

Output:
Linked Blocking Deque 1: [1, 2, 3, 4]
Is LBD1 equal to LBD1: true
