Question 1: Write a program in JAVA that displays a menu as shown in the sample run and asks user to two numbers. You can enter a, s, m, d, r or p for choosing an addition, subtraction, multiplication, division, remainder or power. Depending operation type, you will evaluate the result of an operation. For a division operation such as number1 / number2, you should check number2 so that it is not zero. Your program should be inside of a loop and exit loop whenever you enter 6. Select Operation: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Remainder 6: Power 6: Exit Enter a choice: m Please, enter the first number: 20 Please, enter the second number: 10 Result of 20 * 10 = 30 Select Operation: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Remainder 6: Power 6: Exit Enter a choice: a Please, enter the first number: 21 Please, enter the second number: 11 Result of 21 + 11 = 32

Write a program in Java Write a program that has variables to hold three test scores. The program should ask theuser to enter three test scores and then assign the values entered to the variables. The programshould display the average of the test scores and the letter grade that is assigned forthe test score average. Use the grading scheme in the following table:
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…
you are asked to test the log10 function (double log10(double a)) in Java Math library. You do not have the source code for the function however the specifications of the function are available. The specifications of the function as follows: Function returns the base 10 logarithm of the given double value. If the argument is equal to 10n for integer n, then the result is n. If the argument is NaN or less than zero, then the result is NaN. If the argument is positive infinity, then the result is positive infinity. If the argument is positive zero or negative zero, then the result is negative infinity. *NaN is a numeric data type value which stands for “not a number” (e.g. Double.NaN) 1. Explain why performing exhaustive testing (testing with all possible inputs) on this method might not be considered efficient testing and propose an efficient testing strategy. 2. Explain how the proposed testing strategy is performed and list the minimum amount of test inputs required to…
Write a Java program (TicTacToe.java) for playing tic-tac-toe. You may assume that two human players are playing against each other. Your program should display an updated board before every turn, prompt the user to enter the row and column in which to play, and display "X wins!", "O wins!", or "Tie!" at the end of the game. Here is a sample run of a correct program (user input indicated by orange text):Let's play Tic-Tac-Toe! - - -- - -- - -Enter a row and column (1, 2, 3) for player X: 2 2 - - -- X -- - -Enter a row and column (1, 2, 3) for player O: 2 3 - - -- X O- - -Enter a row and column (1, 2, 3) for player X: 1 1 X - -- X O- - -Enter a row and column (1, 2, 3) for player O: 1 3 X - O- X O- - -Enter a row and column (1, 2, 3) for player X: 3 3 X - O- X O- - XX wins!

Decidewhich of the following statements is either true or false and re-correct the false ones.1. The value of the following logical expression is true (1 + 2 == 2) || (4 - 4 == 0)2. In Java, once a variable is declared, it will be visible and could be used anywhere in theprogram.3. Strings are primitive data type in Java.4. In Java, we can initialize a variable during its declaration.5. do ... while repetition statement gives full control on the code block to be repeated.6. All binary operators except for the assignment operators are evaluated from Left to Right7. A ragged 2D array is a 2D array in which each column may contain different number of rows.8. Each row in a 2D array could be dealt with as 1D array.9. The following statement creates and initializes the array x:int x[] = {10, 20, 30, 40, 50};10.

IN JAVA The following program generates an error. Why? public static void printSum(int num1, int num2) {System.out.print(num1 + num2);}public static void main(String args[]) {int y;y = printSum(4, 5); return 0;} A. printSum() is missing a "return;" statement. B. The values 4 and 5 cannot be passed directly to printSum() C. main() has a return statement that returns the value 0 D. printSum() has void return type, so cannot be assigned to a variable
