Java:) 1. (The MyPoint class) Design a class named MyPoint to represent a point with x and y-coordinates. The class contains:

 Two data fields x and y that represent the coordinates.

 A no-arg constructor that creates a point (0, 0).

 A constructor that constructs a point with specified coordinates.

 Two get methods for data fields x and y, respectively.

 A method named distance that returns the distance from this point to another

point of the MyPoint type.

 A method named distance that returns the distance from this point to another

point with specified x and y-coordinates.

Implement the class. Write a test program that creates two points (0, 0) and (10, 30.5)

and displays the distance between them.

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

The computers in the sales department did not have enough data storage capacity to contain all the information the department needed to store, and it was taking a long time for team members to access the data they needed. to fix the problem, the technician installed new, larger hard drives on all the computers.
