You're interested in looking at trending Twitter hashtags, but you notice that people aren't very consistent with how they use them. Specifically, the capitalisation and punctuation in hashtags is inconsistent. You decide to write a program to read in tweets, normalise any hashtags present, and print out a tally of frequencies. Hashtags should only include words starting with #. All punctuation should be removed from the

I needed  some help with this java homework assignement. We use eclipse.     CIS365 Hw1: Count LetterWrite a Java program (CountLetter.java).  Input a sentence from keyboard. Print out how many letters "a", "e", "o" and the percentage of each letter in the whole sentence. Please enter a sentence, ended by period '.':  (5 points)Sentence....                                                    (10 points)There are 20 letters                                                       (10 points)a: 1,  5%                                                                                  (20 points)e: 0,  0%                                                                                 (20 points)o: 4,  20%                                                                             (20 points)

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline.  But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far...   import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…

You've decided to test the wifi speed in the classroom at the beginning of every lecture. Create a program that will tell you if the wifi speed over the past 3 classes has increased, decreased, or neither. If the wifi speeds are sorted and increasing, then print out "The wifi is getting faster!". If the wifi speeds are sorted and decreasing, then print out "The wifi is getting slower!". If the wifi speeds are unsorted or if two or more speeds are the same, then print "The wifi speed is changing unpredictably." The user should input 3 non-negative numbers (double) separated by spaces. Sample runs: Enter wifi speeds over the last 3 classes: 162 180 225 The wifi is getting faster! Enter wifi speeds over the last 3 classes: 37.5 21.2 19.9 The wifi is getting slower! Enter wifi speeds over the last 3 classes: 162 135.3 225 The wifi speed is changing unpredictably. Ensure you are doing basic input validation, output Please enter a valid input. if the user inputs a negative wifi speed. Make…

Create a card game in which the dealer shuffles the deck and deals 13 cards to the player. The player sorts her hand and says whether it includes the King of Hearts. Repeat 4 times so all the cards are dealt eventually. Internally, the player should return true or false without writing to the console. In response, the dealer should write on the console, "You won!" or "You loose again."

Write a program that compares the area of two rectangles. You can do this several ways, one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. The area of a rectangle is the rectangle's length times its width. Name the source code file yourName_HW4.py. Test and run the program. Capture the output console and save it as an image file named

Write a program to build a calculator. Instead of a typical calculator which reads in-order expressions and evaluates them, build a calculator that takes in numbers and assigns the operations to yield the highest value expression. The current operations on the calculator only handle pairs of parentheses, and the operators for addition, subtraction, multiplication, and division. The calculator can rearrange the numbers if it helps find the optimal value. For example, the list:4.0 5.0 3.0 2.0 1.0using the calculator should find the optimal expression yielding the maximum value to be:4.0 * 5.0 * 3.0 * (2.0 + 1.0) = 180Input from the keyboard a list of up to 10 floating-point values from-100000.0to100000.0. Output to the screen a single floating-point value rounded to two decimal places representing the highest value expression that the calculator could create by inserting the symbols( ) + - * /into the given expression. Assume at least one number in the list and only the operators listed…

I need help with Java code. I'm not sure how to start...

In java: ( no stringbuild or chart.append) the program must produce a neatly labeled bar chart depicting the relative values to each other. Note that there is no interactive input and no use of command line arguments. The program at this stage uses values programmed directly into it. The program output must include the original values as well as the bars. The example below shows the relative number of performances of some Broadway musicals (in picture) You choose the width of the chart. In the example above, it's 60, but it can be different. The largest value in your set should use the entire width, the rest of the bars will be proportionately shorter. Since you're assigning the values in the program, you know the maximum and no special logic is required to find it You must compute and display the "scale" of the chart (i.e. how many units one bar symbol represents) Each bar is labeled with the entity and value You may choose any symbol for your bars   3. In…

When we say arithmetic expression, we mean a kind of expression you can type in a very basic desk calculator. That is, neither variables nor brackets are allowed. It contains only numbers and four arithmetic operators, +, -, *, and /.   The following are some examples of arithmetic expression:   Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. Number strings mixed with arithmetic operators - e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2.   An example of FA diagram for recognising a non-negative integer is given below. You may use it as a start point. You need to add a few more states and transitions to handle numbers with decimal point and signs (e.g. -5, +2, 0.21, -32.6, +99.05, but not the form 1.0E-3). Most importantly, you also need to add a few more things to deal with the arithmetic operators +, -, *, /.
