Program Plan Intro

Program plan:

AsterisksChartWithCaptions.java

Create a class named “AsteriskChartWithCaptions”.

Define a function named “readinputValues”.

Using “arrvalues.clear()” method clear all the values from the “arrvalues” array list.

Using “arrcaptions.clear()” method clear all the values from the “arrcaptions” array list.

Declaring “in” as an object of “Scanner” class.

The scanner “nextInt()” method reads a number from the user and store into the variable “num”

Using “while(num >= 0)” loop, checks whether “num” is greater than or equal to “0” or not .

If the condition is true,

Add the “num” value into the “arrvalues” array list using the “add()” method.

Read a string from the user and store into variable “cap”.

Add the “cap” value into the “arrcaptions” array list using the “add()” method.

Define an “int” function named “findMaxElement”.

Declare an integer variable named “maximumval” and access the input list using “get()” method.

Using enhanced “for” loop, iterate and find the largest element in the array list.

Inside the loop, the conditional statement “if” checks whether “a” is greater than “maximumval” or not

If the condition is true, the maximum value will be stored in the variable “maximumval”

Return “maximumval”.

Define an “int” function named “findtheLongCption”.

Declare an integer variable named “maximum” and find the first caption’s length and store into the variable “maximum”.

Using enhanced “for” loop, iterate and find the length of the longest caption in the array list.

Inside the loop, the conditional statement “if” checks whether the length of “b” is greater than “maximum” or not

If the condition is true, assign the length of “b” into the “maximum” variable

Return “maximum”.

Define a function named “printChartWithCaptions”.

Declare an integer variable named “maximum” and call the function “findMaxElement”.

Declare an integer variable named “large” and call the function “findtheLongCaption”.

Inside the “for” loop,

Retrieve a element from the “values” using the “get()” method and store it into the variable “number”.

Retrieve a string from the “captions” using the “get()” method and store it into the variable “caption”.

Subtract “caption.length()” from “large” to compute the spaces before caption and store the value into the variable named spaces.

Using “for” loop, print the spaces before caption.

Next, declare an integer variable named “asterisks” and calculate the number of asterisks and store into the variable “asterisks”.

At last use “for” loop, to print and display the bar chart of asterisks based on input list and largest element in the list.

Define a main function.

Create an ArrayList object called “arrlist” which will store integer values.

Create an ArrayList object called “arrcaptions” which will store string values

Call the function “readinputValues” and pass the “arrlist” and “arrcaptions” as parameter to read a sequence of positive integer values and captions from user and construct an arraylist.

Call the function "printChartWithCaptions" and pass the “arrlist” and “arrcaptions” as parameter for displaying the bar chart of asterisks with captions based on largest element and input list in the array list.

That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
