In Java,
Write a program that prompts the user to enter a full name consisting of three names (first middle last) into one String variable. Then use methods of class String to:
print the number of characters in the full name, including spaces
print just the middle name and the number of characters in it.
print the three initials of the name
print the last name in all upper case.
print the full name in the usual alphabetical format (last, first middle) and proper case.

Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allenarrow_forwardin Java, Write a program that reads student scores, gets the best score, and then assigns grades based on the following scheme:• Grade is A if score is ≥ best − 10• Grade is B if score is ≥ best − 20;• Grade is C if score is ≥ best − 30;• Grade is D if score is ≥ best − 40;• Grade is F otherwise.The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades. Here is a sample run: number of students: 4 scores are: 40.0, 55.0, 70.0, 58.0 Student 0 score is 40.0 and grade is C Student 1 score is 55.0 and grade is B Student 2 score is 70.0 and grade is A Student 3 score is 58.0 and grade is Barrow_forwardWRITE IN JAVA USING JOptionPane.showInputDialog Write a program that reads a sentence as input and converts each word to “Pig Latin”.

- in java First, read the first floating-point number from input. Then, read the remaining floating-point numbers while the floating-point numbers are in the range -20.0 to 20.0, both exclusive. Output the total number of floating-point numbers read in the given range. End with a newline. Ex: If the input is -14.0 -26.5 -13.0 -17.5 -18.0 -16.5 -12.5 -15.0, then the output is: Number of floating-point numbers read: 1 Note: -20.0 and 20.0 are not in the given range. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java.util.Scanner; public class CountRead { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); doubleinputData; intcountRead; countRead=0; /* Your code goes here */ } }arrow_forward3.

- When we say arithmetic expression, we mean a kind of expression you can type in a very basic desk calculator. That is, neither variables nor brackets are allowed. It contains only numbers and four arithmetic operators, +, -, *, and /. The following are some examples of arithmetic expression: Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. Number strings mixed with arithmetic operators - e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2. An example of FA diagram for recognising a non-negative integer is given below. You may use it as a start point. You need to add a few more states and transitions to handle numbers with decimal point and signs (e.g. -5, +2, 0.21, -32.6, +99.05, but not the form 1.0E-3). Most importantly, you also need to add a few more things to deal with the arithmetic operators +, -, *, /.arrow_forwardIN JAVA. Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 15 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98arrow_forwardWrite a Program that take 2 string from user and print the whole with greetings.
