Explanation of Solution

Name of the method called to get an object’s hash code:

The “hashCode()” method is called to get an object’s hash code in the program.

• The hash code is an integer value, which is a characteristic of an object.
• The hashing algorithm is used to evaluate a hash code for an object.
• Different objects in the code can contain the same data and a hashing algorithm should give the same hash code for those objects.

Example:

//store the string value into the variable

String str1 = new String ("Barney");

String str2...
