- Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…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.14.

- Please use java A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in example below. (1) Design a class named Complex for representing complex…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.

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.
