Lab ADT

Define a Complex class and write an object oriented program to compute (2+3i)+(4+5i) in Java.The methods should include an access and a mutator.

Class definition 3

Do Display 4.7 (3rd, 2nd ed.) or 4.5 (1st ed.). Then use Display 4.8 to call 4.7.QuestionIn Display 4.7, if the method setDate has the parameter as setDate(int month, int day, int year), what kind of changes should be made in its body of codes?

Homework 4-13-2009 Fraction Multiplication

Write a program to implement a method that can multiply 2 fractions. You will implement a class called Fraction consisting of a numerator and a denominator. The multiplication of2 fractions should be equal to a fraction.Use 1/2 * 1/3 as the test.Hints:Fraction f1, f2;f1.multiply(f2);due date: 4/27/2009

lab Fraction equality test

Write a program to implement a method that can check whether 2 fractions are equal. You will implement a class called Fraction consisting of a numerator and a denominator. The equality test of 2 fractions should return a boolean value.Use the following as the tests.* 1/2, 2/4* 5/6, 6/7Hints:Fraction f1, f2;f1.equals(f2);

lab Fraction Addition

Write a program to implement a method that can do additions of 2 fractions. You will implement a class called Fraction consisting of a numerator and a denominator. The additions of2 fractions should be equal to a fraction.Use 1/2+1/3 as the test.Hints:Fraction f1, f2;f1.add(f2);

Homework 3-30-2009: counter

Define a class called Counter whose objects count things. An object of this class records a count that is a nonnegative integer. Include methods to set the counter to 0, to increase the count by 1, and to decrease the count by 1. Include an accessor method that returns the current count value and a method that outputs the count to the screen. Write a program to testcounter.reset();counter.inc();counter.inc();counter.dec();counter.output();

lab class definition 2

Study Display 4.4 (2nd ed. and 3rd ed.) or Display 4.2 & Display 4.3 (1st ed.) and then1. Comment out date.setDate(6, 17, year); by // date.setDate(6, 17, year);2. At the next line below, add date.readInput();3. Run the program again. Fix any problems you may encouter along the way.4. At the last line of your program, add System.out.println(date.month);and see what happens. Why?
