Is the assignment operator a unary operator or a binary operator. Select one or the other.
True or false? In Java, when using the assignment operator, the value stored in memory and represented by the right operand is copied into the memoryrepresented by the left operand. If your answer is False, explain why.
Show two of the shortcut assignment operators and explain how they behave by comparing them with the regular (non-shortcut) versions. Hint: the (^=) operator is a shortcut assignment operator.
Write a Java application that clearly illustrates the difference betweenthe prefix and the postfix versions of the increment operator. Provide a termination message that displays your name.
Write a Java application that illustrates the use of the followingrelational operators:
<><=>=
==!= Provide appropriate text in the output. Also provide a termination message with your name.
write a Java application that illustrates the use of the followinglogical or conditional operators:
&&||! Provide appropriate text in the output. Also provide a termination message with your name.
What is the meaning of the following two images?
This image was inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.
The image is also an example of the kinds of things that we do in my course titled ITSE 2321, Object-Oriented Programming.
This image was also inserted for the purpose of inserting space between the questions and the answers.
