- To determine if two variables of the same basic type have the same value in Java, we use the == operatorTrue or false: Java variables cannot start with a capital letter.Guessing game: Read a number until it's equal to a chosen number (first it can be a hard-coded constant or #define, or you can check rand() later). In case of wrong guessing help the user by printing whether the guessed number is to small or too big. ( in C language)
- User Defined Function: Void Function Create a JAVA program that will add, subtract, multiply and divide two numbers. Use user defined function for each operator Any number divided by zero will result to undefined Use int or double data type only for all variables declaredEXPECTED OUTPUT:Lad ℗ Ⓒ Understanding Nested if Statements Summary In this lab, you complete a prewritten Java program that calculates an employee's productivity bonus and prints the employee's name and bonus. Bonuses are calculated based on an employee's productivity score as shown below. A productivity score is calculated by first dividing an employee's transactions dollar value by the number of transactions and then dividing the result by the number of shifts worked. Instructions Productivity Score Bonus <30 31-69 70-199 ≥ 200 1. Ensure the file named EmployeeBonus.java is open. 2. Variables have been declared for you, and the input statements and output statements have been written. Read them over carefully before you proceed to the next step. $50 $75 $100 $200 3. Design the logic, and write the rest of the program using a nested if statement. 4. Execute the program by clicking Run and enter the following as input: Employee's first name: Kim Smith Number of shifts: 25 Number of transactions: 75…True or False 6. In languages that require variable declarations, a variable’s declaration must appear before any other statements that use the variable.
- CPSC 130: Introduction to Computer Programming I Program 3: Decisions In this programming assignment, you will implement two Java programs that deal with decisions. Part1: Determine correct quadrant for angle Complete the program below so that it prompts the user for an angle in degrees, and prints out the quadrant in which the angle is located, represented by Roman numerals, as shown in the following figure. 180⁰ II E III 90⁰ 270⁰ IV Notice that the value of the angle starts at zero degrees at the rightmost point of the circle, moving counterclockwise around the circle as the number of degrees grows. For instance, if the input angle has 100 degrees, it is in quadrant II, while an angle of 300 degrees is in quadrant IV and an angle of 45 degrees is in quadrant I. Each quadrant contains 90 degrees and starts at a multiple of 90. For example, 89 degrees is in quadrant I and 90 degrees is in quadrant II. All the input angle values must be integers between 0 and 359. If the value of an…• FormulaEvaluator.java Requirements: Evaluate the following expression for any value of the variable x, and save the result in a variable of the type double. You must use the abs(), pow(), and sqrt() methods of the Math class to perform the calculation. You may use a single assignment statement with a somewhat large expression, or you may break the expression into multiple assignment statements. The latter may be easier to debug if you are not getting the correct result. 5x +3} ( √8x* — 6x²³ + 4x² + |20x+1) (9x³+7x² +5x+3) Next, determine the number of digits to the left and to the right of the decimal point in the result. [Hint: You can convert the double variable into a String variable using the static method Double.toString(result). Then, on this String variable use the indexOf() method from the String class to find the position of the decimal point (".") and use the length() method to find the length. Knowing the location of the decimal point and the length of the String, you…JAVA Programming Language: According to the American Heart Association, as you exercise you should periodically check your heart rate to ensure you are in your target zone. Your target zone is a range that is 50% to 85% of your maximum heart rate. The formula for calculating a persons maximum heart rate is 220 minus your age in years. Write a program that reads the users current heart rate, birthday, and the current day (each consisting of month, day, and year). The program should calculate the persons age (in years), the person's maximum heart rate, and the person's target heart rate zone range. Output the users age, current heart rate, target zone range. If their heart rate is in the target zone congratulate them, if it is out of their target zone warn them. Required Methods (Write these first and use them in your algorithm): (your code, particularly for computeAge, must be 100% clear and documented - it's the core of this assignment!) int computeAge(int birthMonth, int birthDay,…
- Assignment1 In this assignment you have to write a java program Assignment1 that contains all three zeros of the calculates the following third degree polynomial: 23 = -1 The solutions must be determined using the Newton-Raphson method. Work with an absolute accuracy of ɛ =0.00001. It means |x+1- X,] > ɛ Make sure your output looks like the Example output ( Like here below ). The real part and imaginary part must be rounded to three decimal places. The order of the zero points are not important. This order may be different for you. Example Output: PS C:\ Users\ Sam\Documents\Homework\PR> java Assignment1 Zero point 1 is equal to : -1.0 Zero point 2 is equal to : 0.5 - 0.866i Zero point 3 is equal to : 0.5 +0.866i Example Output for: f(z)= z³ +1Rolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…Java Lab 5 Problem Statement Write a program that quizzes the user on the names of the capital cities for all the states in the United States. Each state is presented to the user, and they must enter the name of the capital. The program then either tells the user they're correct or tells them the correct answer. The user's answer should not be case-sensitive. At the end, the program tells the user the total number they got correct. Here's an example: What is the capital of Alabama? MontogomeryThe correct answer is Montgomery.What is the capital of Alaska? juneauThat is the correct answer!...You got 32 out of 50 correct! The state capitals will be stored in a 2D String array of size 2 x 50, with the first column the name of the state and the second the name of the capital city, for all 50 states. To create the state capitals array, follow these instructions: Copy the String from the attached file into your program (found below these instructions). The String is a pipe delimited…
