Describe the exclusive OR operation (XOR) function and explain where XOR encryption is used.
What will be an ideal response?
The exclusive OR operation (XOR) is a function of a binary operation in which two bits are compared and (1) if the two bits are identical, the result is a binary 0, and (2) if the two bits are not the same, the result is a binary 1. XOR encryption is a very simple symmetric cipher that is used in many applications where security is not a defined requirement.

Given the following method header, which of these method calls is incorrect?
``` public void displayValue(int x, int y); ``` a. displayValue(a, b); // where a is a short and b is a byte b. displayValue(a, b); // where a is an int and b is a byte c. displayValue(a, b); // where a is a short and b is a long d. All of these would give an error.
