1.1 Part 1: On Unary Operators ( 30 points) Unary operators are used to do operations on only 1 operand. This part of the lab will test your understanding of the unary increment operator. The steps for this part of the lab are as follows: 1.1.1 Steps 1. Create a variable x of type integer and initialize it to a value of your choice 2. Then set integer variable y to ++x and integer variable z to x++ 3. Your program should print the following text using the concept of String concatenation. Replace with y,z and x respectively. Value of y is , value of z is , and final value of x is 4. Why are the printed values of y and z the same? Write an answer to this question as a comment in the Lab3.java file that is provided. Please refer to the lecture slides on "Basic Java Program Structure" to see how to write comments in Java. 1.2 Part 2: On Arithmetic Operators (20 points) Write a program to calculate the perimeter of a rectangle. 1.2.1 Steps 1. Choose the appropriate data type for the rectangle's length, width, and perimeter. You can choose any value within the range for length and width and use that to calculate the perimeter. 2. Your program should print the following text using the concept of String concatenation. Replace with length, width, and perimeter respectively. The perimeter of a rectangle with length and width is
