Create a class to print the area of a square and a rectangle. The class has two methods with the same name but different number of parameters. The method for printing area of rectangle has two parameters which are length and breadth respectively while the other method for printing area of square has one parameter which is side of square.

Write a Rectangle class. Its constructor should accept length and width as a parameter. It should have methods that return its length, width, perimeter, and area. (Use Java) Show a demonstration where you create two separate rectangles.

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 }

in JAVA Assume that a receipt id contains characters that represent information or that can be used as a code to determine something about the purchase. For example: if an id has an 'x' followed by two 'y's, it means that the purchase was a final sale and cannot be returned. Or if an id has an 'a' followed by three 'b's, it means that a coupon was used for purchase. Write a static method for the Receipt class to test whether a receipt id meets such a criteria. Does the id meet the criteria? The criteria is described by three pieces of data, passed in as parameters: char firstTarget char second Target int countOfSecond After First A receipt id meets the criteria if: the id contains the first target character and the second target character appears exactly the specified number of times after the first target character appears Note: the first and second char could be the same char! Carefully review the provided driver program for examples of ids that meet and don't meet criteria. For full…
