Java Tutorial | InBuilt Class Object Methods | toStr(), equals() and hashCode() Method

Java toString() Method Object class is present in java.lang package. The toString() method returns the String representation of the object. If you print any object, Java compiler internally invokes the toString() method on the object. So overriding the toString() method, returns the desired output. Note: Default behavior of toString() is to print class name, then @, then unsigned hexadecimal representation of the hash code of the object. The equals() method checks whether two objects are equal. equals() Return Values: returns true if two objects are equal returns false if two objects are not equal Note: In Java, if two reference variables refer to the same object, then the two reference variables are equal to each other. What is meant by hashCode in Java? hashCode in Java is a function that returns the hashcode value of an object on calling. It returns an integer value which is generated by the hashing algorithm. The process of assigning a unique value to an object or attribute using an algorithm, which enables quicker access, is known as hashing. hashCode in Java helps the program to run faster. For example, comparing two objects by their hashcodes will give the result 20 times faster than comparing them using the equals() function.  If this video is useful to you, please like and share If you didn't subscribe kindly subscribe.
