The equals() method of java.util.concurrent.ConcurrentSkipListMap is an in-built function in Java which to check the equality of this Map object with the specified object. The method returns true if the given object is also a map of the previous one and the two maps have the same mappings.
Syntax:
public boolean equals(Object ob)
Parameter: The function accepts a single mandatory parameter ob which specifies object to be compared for equality with this map.
Return Value: The function returns true if the specified object is equal to this map.
Below programs illustrate the above method:
Program 1:
// Java Program Demonstrate equals()// method of ConcurrentSkipListMap import java.util.concurrent.*; class GFG { public static void main(String[] args) { // Initializing the map ConcurrentSkipListMap<Integer, Integer> mpp = new ConcurrentSkipListMap<Integer, Integer>(); // adding elements in map for (int i = 1; i <= 5; i++) mpp.put(i, i); // equals operation on map System.out.println(mpp.equals(4)); }} |
Output:
false
Program 2:
// Java Program Demonstrate equals()// method of ConcurrentSkipListMap import java.util.concurrent.*; class GFG { public static void main(String[] args) { // Initializing the map ConcurrentSkipListMap<Integer, Integer> mpp = new ConcurrentSkipListMap<Integer, Integer>(); // adding elements in map for (int i = 1; i <= 5; i++) mpp.put(i, i); // equals operation on map System.out.println(mpp.equals(3)); }} |
Output:
false
