Create a Java program that will display the student's information. The program should perform the following: Ask the first name, middle initial and last name of the student. • Prompt the user to select between old student and new student by pressing either O (old student) or N (new student). • If O is pressed, ask the student to enter the following grades per term: o Prelim o Midterm o Prefinals o Finals • Compute the final grade of the student by using given formula: FG = ((Prelim 20%) + (Midterm 20% ) + ( Prefinals 20)+ (Finals 40%)). Display the full name of the student with his/her accumulated grade using the format given. If N is pressed, ask the student to enter his/her average grade then display the full name grade. • • Grade Format: o 1.00=99-100 o 1.25 96-98 o 1.50=93-95 o 1.75 90-92 o 2.00=87-89 o 2.25=84-86 o 2.50 81-83 o 2.75 76-80 03.00 = 75 o 5.00= Below 75 If an invalid letter is pressed, display an error message.
Create a Java program that determines if two (2) words rhyme. Write the import statements to be able to use Scanner, Pattern, and Matcher.Enable user input.Create three (3) String variables.word1 shall store the first word.word2 shall store the second word.sub shall store the last two (2) letters of word1.Initialize a Pattern as defined by the regular expression "[______]{___}" + sub + " " For the first blank, allow uppercase and lowercase letters. For the second blank, allow either 1 or 2 letters before sub (contains the last two (2) letters of word1).Initialize a Matcher to store a possible match between your pattern and word2.Use the matches() method to check if the two (2) words rhyme. Sample Output: Enter the first word: glam Enter the second word: slam slam rhymes with glam //word2 has 2 letters before 'am' Enter the first word: glam Enter the second word: ham ham rhymes with glam //word2 only has 1 letter before 'am' Enter the first word: beat Enter the second word: treat…

a. Write Java classMessage that automatically gives each created Message object a unique serial number, starting at 1 for the first message. (Hint: static) b) Write statements that create three Message objects. Show and explain serial numbers for these objects.
Assume the int variable number has been properly declared and initialized (with some value unknown to you). Write a Java code fragment that will do the following: (a) If the number is positive, print "plus" (no quotations marks, just the word plus) (b) If the number is negative, print “minus" (c) If the number is zero, print "zero". 2.
