Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet eâ¦xtends java.util.HashSet. The method add() is overridden in LinkedHashSet.
Note that equal objects must have equal hash codes. Therefore, when overriding the equals method, you must also override the hashCode method. Failure to do so violates the general contract for the hashCode method, and any classes that use the hash code, such as HashMap will not function properly.
