Write a program to produce an array of integer random numbers. Yourprogram should find out from the user how many numbers to store. It should then generate and store that many random integers (the random numbers must be between 1 and 999 inclusive). The program should then determine the smallest number, the largest number, and the average of all the numbers stored in the array. Finally, it should print out all the numbers on the screen, five numbers to a line with spaces in between. Once the contents of the array have been printed to screen, display the smallest number, largest number, and average determined previously. You should ensure that your program design in modular.The Random class of Java library (java.util.Random) implements a randomnumber generator. To generate random numbers, you construct an object of q the class Random, and then use the method nextInt(n) which returns a number between 0 (inclusive) and n (exclusive). Eg:import java.util.Random;.....Random generator = new Random();.....//generate a random number between 0 and 99 (inclusive)int nextRand = generator.nextInt(100);Alternatively use Math.random(), which returns a random valuein the range 0.0 to 1.0 (then adjust to the correct range)

Assume that you measured the length of an object as 50 mm using a digital caliber. The measurement was made at 300 + 5 K. What is the actual measurement result? (Resolution of the digital caliber: 0.04 mm, coverage factor: 3, linear thermal expansion coefficients of the digital caliber and the sample are 14*10-6 KP)

The circuit below shows a filter commonly used as the output stage of a power supply. In this application, Vin(t) is switched between 0 and a DC input supply voltage (12V in this case). The filter smooths the switched input so that it is close some desired output from 0-12V. In this exercise, you are interested in determining the start-up behaviour of the system. To this end, do the following: a) Find the transfer function Vout(s) . You may assume that the capacitor and inductor are initially de- Vin(s) energised. b) Att = 0, Vin(t) is switched to 12 V (i.e. Vin(t) = 12u(t)). Find the time response Vout(t) = [-{Vout(s)}. Please use partial fraction expansion and the Laplace Transform table to conduct the inversion(s), showing all of your work and explaining your logic clearly to receive full credit. c) How long will it take for vout (t) to reach 6V? You may use computer tools here, but please clearly explain your logic for full credit. d) Sketch (by hand) the Bode plot for G(s) with the parameter values from part b. As a part of this, please carefully compute and label: i. All asymptotes (e.g. low-frequency & high frequency) All corner frequencies iii. The frequency and magnitude (in dB) of any resonances (if they exist) 50 x 10-3 H 000m 0.25 12 Vin(t) 0.2F 112 Vout(t) Figure 2: System for Question 3
