@Canonical: It’s very useful annotation. It provides the combination of features of @ToString (default implementation of toString() method based upon the fields in the class), @EqualsAndHashCode(default implementation of equals() and hashCode() method of the class based upon the fields in the class) and @TupleConstructor (provides the classical constructor with default properties). <\/p>\n

}<\/p>\n
Person person = new Person(name:"Mohit Garg",address:"Address",city: "city")
\nPerson person1 = new Person("Mohit Garg","Address","city")<\/p>\n
println("Check two objects are equal:::"+(person.equals(person1))) \/\/ Both objects will be equal because of same hashCode. (Output:true)<\/p>\n
