Question
First exercise:
The user enters three words in one line separated by a space between each word and then presses the enter button to print the program with the most word with letters and if it finds two or more words equal in being the longest word? The program has to decide for itself which word to print
(Note: It is forbidden to use the .next method for the string and use the nextLine method to replace it)
The second exercise:
The user enters the number of cycles of row (horizontal lines) and the number of stars (*) in each column (columns) and the program prints the cycles and number of stars based on the data entered by the user

Transcribed Image Text:Task 1- ThreeWords.java
Write a Java program called ThreeWords that prompts (asks) the user
to enter three words, separated by a space, on the same line and read
in using the .nextLine( ) method of the Scanner class. You may NOT
use the .next(() method of the Scanner class in this Task. Using the .next( ) method of
the Scanner class will result in this Task being awarded 0, regardless of correct
execution.
(You may assume that the user always enters 3 words, each word separated by a
single space.)
Once the user has entered the three words, the program displays to the screen the
longest word, that is, the word with the most characters. In the event of one or more of
the words having the same number of characters, the program may decide which word
it displays to the screen.
Based on the restrictions above, the skeleton of your program will look like this:
Some sample runs of the program are included below (user input is in bold):
> java ThreeWords
Enter 3 words >> hello dragon at The longest word is dragon
> java ThreeWords
Enter 3 words >> finished this Task1 The longest word is finished
> java ThreeWords
Enter 3 words >> aa a abc The longest word is abc

Transcribed Image Text:Task2 - Box.java
Write a Java program in a file called Box.java that outputs a box of stars (*) on the
screen. Prompt the user for how big (row x column) the box should be.
For example:
Please enter the size of the box (row column): 3 4

- Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…arrow_forwardLab 6: Multiplication Table Write a program that will continually ask the user to enter a positive number from standard input and print out the multiplication number table until user enters an alphabet (non number) to quit. Once user enters 'Q' or anything other than a number, the program will print out “Have a nice day" and then exit the program. After reading the user's input the positive number, the program will print out the multiplication table of the inputted number. For example, if user enters 5, the table should be: Multiplication table for 5 is: 2 3 4 5 4 6 8 10 9 12 15 8 12 16 20 5 10 15 20 25 Your program needs continuously ask the user to enter the a positive number until the user enters Q or q to exit the program. Your program must print out your names and lab info as you did in previous lab similar to the following: Program written by: Ron Sha Course info: Cs-102 Lab 6 - Multiplication Table Date: Wed Oct 14 11:35:18 2020 Activate un 1.2345arrow_forwardA for construct is a loop that processes a list of items.

- JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTERarrow_forwardPrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general.

Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist.
