- For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither.Java. please take note of the following correction: The sentence "Please note that +/- sign represents private and public modifiers respectively" should be "Please note that +/- sign represents public and private modifiers respectivelyWriting a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…
- Give an example of declaration statement and an example of an assignment statement that will be used in a Java program that converts Celsius to Fahrenheit and Fahrenheit to CelsiusCalculate your Physics final Write a Java program to solve the following problem: grade based on the following: Assessment Percent Lab Activity(ies) Quiz (zes)/Test (s) 10% 10 Assignment (s) 208 Midterm Exam (8) 20% Final Exam 40% Theory grade is the quiz/test, midterm and final exam marks. Practical grade is the assignment and lab marks. Final grade is all five marks. But the calculation of Final grade needs to comply with the following rule: If either of the practical or theory grade is less than 50%, the final grade is the lesser of the two. A grade letter must be assigned based on the final grade (See the courses outline for the distribution of grades) You must implement input validation for each mark as follows: Lab mark must be out of 10. Quiz/Test mark must be out of 10. Assignment mark must be out of 20. Midterm mark must be out of 20. Final Exam must be out of 40. Bonus: Modify your code so that you can calculate and display grade for N number of students. Your program must…In JAVA ASSIGNMENT DESCRIPTION: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. THE CODE I HAVE SO FAR: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point like 75.5, versus int for integers like 75. caffeineMg = scnr.nextDouble(); System.out.printf("After…
- Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.Correct the following wrong statements. 1. do … while repetition statement gives full control on the code block to be repeated.2. In Java, once a variable is declared in a method as local variable, it will be visible and couldbe used in any other method in the program.3. All binary operators except for the assignment operators are evaluated as user intention.4. In Java, byte code is translated to native code by java compiler.5. Each row in a single dimensional array could be dealt with as 2-dimensional array.6. The indices of elements in a single dimensional array named arrElem are from 1 toarrElements[]length.7. In Java, method overloading means that a program may contain more than one methodwith same signatures. Each column in a 2D array could be dealt with as 1D array.8. The following statement creates and initializes the 2-dimensional array values:short values[][] = {10, 20, 30, 40, 50};9. A ragged 2D array is a 2D array in which each row may contain the same number ofcolumns.10.…Any help with this question would really help!! Write the following exercise using Java code.

- Java - Programming Develop a letter-guessing game in this assignment.Requirements:1). When the game begins, generate a random letter between A and Z;2). Display a message "I have a secret letter (A to Z), can you guess what it is?";3). Read the user's answer;4). Compare the user's answer and the random secret letter generated;5). If the user answer is before the random secret letter in the alphabet, display "Incorrect. Trysomething later in the alphabet" and go to Step 2;6). If the user answer is after the random secret letter in the alphabet, display "Incorrect. Trysomething earlier in the alphabet." and go to Step 2;7). If the user answer is the same as the random secret letter, display "Well done. Want to playagain (y/n)?";8). Read the user's answer. If the answer is 'y', go to Step 1. If the answer is 'n', go to Step 9;9). Display "Thanks for playing the game. Goodbye!". The program stops.Run your program several times. Take screenshots. Submit your Java file with the screenshotsWrite a Java program that reads student scores, displays the lowest score, and percentage of fail students and percentage of pass students based on the following scheme: Fail if score is less than 50, Pass otherwise. Your program must consider the following specifications: Use Percentage as the name of your class. Type your name and student number above the class declaration using a block/paragraph comment. Use documentation, comments and code style. Use significant and appropriate identifiers. Use appropriate data type for the variablesHi, I am looking for assistance for a code for Java programming Write multiple if statements: If carYear is before 1967, print "Probably has few safety features." (without quotes). If after 1969, print "Probably has head rests.". If after 1992, print "Probably has electronic stability control.". If after 2000, print "Probably has airbags.". End each phrase with period and newline. Ex: carYear = 1995 prints: Probably has head rests. Probably has electronic stability control.
