Lab 6: Introduction to Arrays Exercise 1: HelloEveryone a. Open the class contained in the file HelloEveryone.java, then compile and run it. // HelloEveryone.java public class HelloEveryone { public static void main( String args[] ) { String[] student = { "Gerald", "Houston", "Duc", "Dustin", "Eli", "Fred", "Gavin", "Jennifer", "Joe", "John", "Kevin", "Lee", "Sahil", "Patrick", "Rishi", "Utkarsh", "Amar", "Brandon", "David", "Sibte"}; for (String name : student) System.out.printf("Hello %s!\n", name ); } // end main } // end class b. The class Arrays in the package java.util has a void method called sort that will act on an array and sort it, in this case in alphabetical order. Import the class arrays and then apply the method Arrays.sort() to sort our students in alphabetical order. Show your class list with students sorted from A-Z. Since the method is static, do not attempt to invoke it from the array as an object. Follow the syntax of other static methods you have seen such as Math.cos() Exercise 2: SearchEveryone and SearchWithWildCard a. Now we want to search the class list for all the students whose name begins with a certain letter. For example Jennifer, Joe and John all begin with J. Open the class SearchEveryone.java . This only finds students whose name begins with the letter 'J'. Enable the user to enter a string at the keyboard. First import the Scanner class and then create a keyboard object. Prompt the user with the following string.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
