1. If you're using eclipse (netbeans has similar features, as do most java IDEs), you can simply got to the "Source" menu, and choose "Generate hashcode () and equals ()". Then you select the fields you want to be considered (in your case the list of enum values. That being said, assuming you already have the enum, here's the code that eclipse

Parameters: Obj - The object to compare with. Return Value: This method returns a Boolean value, It returns true, if the Boolean objects represent the same value. It returns false, if the Boolean objects represent different value.

true. The output is false for the first example and true for the second example. In second example, parameter to equals () belongs String class, while in first example it to StringBuffer class. When an object of String is passed, the strings are compared. But when object of StringBuffer is passed references are compared because StringBuffer

In Java, the == operator is used to compare the references of two objects to see if they point to the same object in memory. The equals () method, on the other hand, is used to compare the values of two objects to see if they are considered equal. In the example above, s1 and s2 are references to two different objects that have the same value.

Usage of @EqualsAndHashcode. The @EqualsAndHashCode annotation in Lombok generates the equals () and hashCode () methods for a given class, using all non-static and non-transient fields by default. To customize the fields used, we can mark them with @EqualsAndHashCode.Include or exclude them with @EqualsAndHashCode.Exclude.

The isEqual () method of LocalDate class in Java checks if this date is equal to the specified date or not. Syntax: public boolean isEqual (ChronoLocalDate date2) Parameter: This method accept a single mandatory parameter date2 the other date to compare to and not null. Return Value: The function returns true if this date is equal to the
The equals() method of java.util.Set class is used to verify the equality of an Object with a Set and compare them. The method returns true if the size of both the sets are equal and both contain the same elements.
Write a Java method that will remove duplicates from a given list. Assuming: Method accepts type List. Return type is void. Duplicates are determined using equals () Main: Creates an instant of List and loads it with duplicate String values. Invoke removeDuplicates (), pass in this list. Outputs modified list to the console.

1. Using equals with numeric values. The example below shows how to see if two integer values are equal to each other or not. System.out.print (number_one.equals (number_two) + " "); 2. Using equals with string values. The following example checks if the given two strings have the same value.
