- Adding two Rational numbers. The result should be stored in reduced form.
- Subtracting two Rational numbers. The result should be stored in reduced form.
- Multiplying two Rational numbers. The result should be stored in reduced form.
- Dividing two Rational numbers. The result should be stored in reduced form.
- Printing Rational numbers in the form a/b, where a is the numerator and b is the denominator.

Problem 1: Java programComplete the Clothing class, the class should have the following instance variables, constructor(s) and instance methods:- An instance variable of type double named price.- An instance variable of type String named type.- An instance variable of type String named size.- A default “no-arg” constructor that sets the price to 29.9, the type to “TShirt” and the size to “Medium”. - An overloaded constructor that takes three parameters and set the instance variables accordingly. - A method named increasePrice that takes no parameters and returns no value, the method increases the instance variable price by 5.- An overloaded method increasePrice that takes a double parameter xand returns no value, the method increases the instance variable price by the value of parameter x.- A method named details which takes no parameters, returns no value, the method prints the Clothing item details in the format shown in the sample output.- Your output should look exactly the same…
Instructions-Java
Assignment is to define a class named Address.
The Address class will have three private instance variables:
an int named street_number
a String named street_name
and a String named state.
Write three constructors for the Address class:
an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice,
a constructor that takes the street values as input but defaults the state to "Arizona",
and a constructor that takes all three pieces of information as input
Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses.
Run your code to make sure it works.
Next add the following public methods to the Address class and test them from main as you go:
Write getters and…

Please help me outarrow_forwardC++ please, Specify, design, and implement a class that can be used in a program that simulates a combination lock. The lock has a circular knob, with the numbers 0 through 39 marked on the edge, and it has a three-number combination, which we'll call x, y, z. To open the lock, you must turn the knob clockwise at least one entire revolution, stopping with x at the top; then turn the knob counter-clockwise; stopping the second time that y appears at the top; finally turn the knob clockwise again, stopping the next time the z appears at the top. At this point the lock will be open. Your lock class should have a constructor that initializes the three-number combination (use 0,0,0 for default arguments). Also provide member functions: a. To alter the lock's combination b.To turn the knob in a given direction until a specified number appears on top c. To close the lock d. To attempt to open the lock e.
