Trying to figure out code for a Java program.

I need an array that holds six objects, which I will place data in. I need a method to sort the array in ascending order and I need to call the method and display the results.

data communication rate

1. Suppose a machine has 20GB of storage space available on a hard disk and receives data over a telephone connection at the rate of 14,400 bps. At this rate, how long would it take to fill the available storage space? 2.Suppose a picture is represented on a monitor screen by a rectangular array containing 1024 columns and 768 rows of pixels. If eight bits are required to code the color and intensity of each pixel, how many byte-size memory cells are required to hold the entire picture? 3.How many cells can be in a computer's main memory if each cell's address can be represented by three hexadecimal digits?

Simple algorithm using the big theta - notation

Sometimes a slight change in a problem can significantly alter the form of its solution. For example, find a simple algorithm for solving the following problem and classify it using big-theta notation: Divide a group of people into two disjoint subgroups (of arbitrary size) such that the difference in the total ages of the members of the two subgroups is as large as possible. ------------------ formular :- all algorithms whose graphs have a shape of parabola such as an insertion sort are classified in the class represented by (n^2) " read big-theta of n squared" All algorithms whose graph have the shape of a logarithmic expression such as the binary search fall in the class represen... click for more

programming and machine independency !

1. Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g is a function that returns the concatenation of the two strings given as its input. If x is the string abcd, what is returned by g(f(x),x)? 2.What ambiguity exists in the statement X <-- 3 + 2 * 5

Decide true or fafalse to the asymptotic notation

For each of these statements, decide if it is · Always true · Always false · Sometimes true and sometimes false If it is always true or always false, justify your answer. If it is sometimes true and sometimes false, give an example of a situation where it is true and a situation where it is false. For questions that involve functions f(n) and or g(n), you should assume that the values of the functions are always positive.
