In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter. The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration: str3 is equal to str1.concat(str2); The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.

Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines. Example Execution (user input in green) Please enter a sentence: Hey there! Your sentence printed vertically is: H e t h e r
Use c++ Programming language Write a program that reads students' names followed by their test scores. The program should output each student's name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of type studentType, which has four components: studentFName and studentLName of type string, testScore of type int (testScore is between 0 and 100), and grade of type char. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Your program must contain at least the following functions: A function to read the students' data into the array. A function to assign the relevant grade to each student. A function to find the highest test score. A function to print the names of the students having the highest test score. Your program must output each student's name in this form: last name followed…
