● ● ● ● ● ● Look at the Sample Run below first which will help you understand better. Declare 4 variables as double type: inputa, inputb, inputc, total Declare 1 variable as int type: intPart Create a Scanner. ● Asks the user to enter input a, b, c. (note which line the user inputs) Calculate the result and store in the variable total. Use casting to show only the integer part of the result. Show the output. Copy&Paste your source code and Screenshot a result for input a = 1.2, b = 1.2, c = 3.

For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }

I was asked to add the three types of comments to this class, each consisting of the same statement (this statement is also printed once). The output/print, block comment, and single line comment has all been marked correct. The Javadoc comment, however, has not. I asked this question earlier and tried implementing that solution, however, it did not work. What should I do to make it work?

Write a test program called TestSquare that: • Creates two Square objects: one object with side's length 5 and the other object with side's length 5.75. • Display the side's length, area, and perimeter of each square object in this order.
Please write in java. Add comments but make the comments short. No need for really long comments. Please keep code very neat and simple , dont add anything unneccesary in the code if you weren't instructed to do so. If youve answered this before please dont copy and paste from a previous question! (Rewrite it in another way)..... Also be sure to read the instructions below carefully. The Instructions attached below will explain everything you'll be doing. NO THIS is not a homework assignment, it's practice work. Please type the code out so that I can copy and paste it into my IDE and see the output for my self but also still provide a screenshot of your output!
