Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

Problem (Circle.java) Implement a class called Circle for representing a circle. The circle has two data members, a Point object representing the center of the circle and a float value representing the radius. Include appropriate constructors for your Circle class. Encapsulate it. Also include methods for finding the area and circumference of the circle. area = pi * radius * radius circumference = 2 * pi * radius. (You may use the static constant pi in the Math class) 5. Override the toString() and equals().
Term by CodeChum Admin (JAVA CODE) Construct a class called Term. It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4

JAVAclass: Main.java, Quadratic.java, TestQuadratic.java Create a class called Quadratic for representing a one-variable quadratic expression of the form: ax2 + bx + c a,b and c here are the coefficients. The class should contain the following methods: * A constructor that accepts values for a, b, and c. * public double getA() * public double getB() * public double getC() * public double evaluate (int x) * will return the value of the expression at point x * public double discriminant() - that will return (b2 - 4ac) * public boolean isImaginaryRoots() - roots are imaginary if (b2 - 4ac) < 0 * public boolean isRealRoots() - roots are real if (b2 - 4ac) >= 0 // these methods can only be invoked if the roots are not imaginary * public float firstRoot() * public float secondRoot() * public boolean isPerfectSquare(); // If the first and second roots are equal * Try to override the toString methods * Write a sample main program that will work as shown below.

java programming Design a class named Complex for representing complex numbers Include methods add, subtract, multiply, divide, and abs for performing complex-number operations Override toString method for returning a string representation for a complex number. The toString method returns (a + bi) as a String. If b is 0, it simply returns a. Your Complex class should also implement Cloneable and Comparable. Compare two complex numbers using their absolute values. Provide three Constructors: Complex(a, b), Complex(a), and Complex() . Complex() creates a Complex object for number 0 Complex(a) creates a Complex object with 0 for b. Also provide the getRealPart() and getImaginaryPart() methods for returning the real part and the imaginary part of the complex number, respectively. (2) Draw the UML class diagram and implement the class. (3) Write a Test program Prompt the user to enter two complex numbers Displays the result of their addition, subtraction,…

Part 2. Library Class Implement a class, Library, as described in the class diagram below. Library must implement the Comparable interface. The compareTo() method must compare the branch names and only the branch names. The comparison must be case insensitive. The equals() method must compare the branch names and only the branch names. The comparison must be case insensitive. Be sure to test the equals() and compareTo() methods before proceeding.

In C# using an array Implement the inventory manager class. This class must have methods that do the following: Add a new item to the inventory manager. Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Test the inventory manager class with a driver program or unit tests. This may be a console application.
