Create the RandomList class with instance variables for an array of integers and a Random object. Write a constructor which takes as input an integer value n> 0 and initialises and populates an array of size n with random integer numbers. Write the void write(int i,int a) which assigns the value a to the ith element of the array, checking to ensure i is a valid index of the array. Write the method boolean contains(int) in RandomList which takes as input an integer-typed parameter and returns true if the value is in the array and false otherwise. Write the class method RandomList rand(long seed,int n) which returns a RandomList object containing n random integer elements with the specified seed. Consult the JavaDocs for the Random class' setSeed method Optional: Write a boolean equals(Object o) which compares two RandomList objects to determine if they are equal. Two RandomList objects are equal iff they contain precisely the same elements. Check to see if the lists are of the same length and then use the contains method. use java

] In the following problems, check suitable rule (Sum, Subtraction or Product) and compute the total number of possible ways in the entire procedure: The password for a computer account can be 6, 7 or 8 characters in length; the characters can be letters or digits. What is the number of ways a password can be formed? How many bit strings of length sixteen start with a 11 or end with 00?

We are drowning in information, while starving for wisdom. The world henceforth will be run by synthesizers, people able to put together the right information at the right time, think critically about it, and make important choices wisely. -E. O. WilsonWhat is the meaning of the sentence above?

a) Digital communication has made technology more pleasant in today's environment. Discuss the proposed techniques for compressing still pictures.b) Among the coding schemes available in communication systems, discuss the one that tries to minimize data size via compression.

I need to solve the following: "ii) Suppose a book has the ISBN number 0444x50090, where the digit represented by x has been lost in transmission. What is x?" I know that for encoding there's a formula one can use but I'm confused about how to use it with the x?

a) A computer has a clock rate of 2GHz. It takes a program 10s to complete on this computer. The number of clock cycles of the program is b) A program has 1x106 instructions. The computer's clock cycle time is 250x10-12 seconds and the CPI is 2.0. Therefore, the CPU time of the program is seconds. c) We use a certain compression program as a benchmark of a certain computer system. The program has 2x10° instructions. The system has a CPI of 0.85, and a clock cycle time of 0.4x109 seconds. When we run the program, it takes 100 seconds to complete on the computer system, whereas it takes 900 seconds to complete on a reference computer. From what you know about the SPEC benchmarks, the SPECratio is
