Chapter 5B Exercise 1 - Extra Exercise - Holy Digits
Holy digits Batman! The Riddler is planning his next caper somewhere on Pennsylvania Avenue. In his usual sporting fashion, he has left the address in the form of a puzzle. The address on Pennsylvania is a four-digit number where:
All four digits are different
The digit in the thousands place is three times the digit in the tens place
The number is odd
The sum of the digits is 27
Write a program that uses a loop (or loops) to find the address where the Riddler plans to strike.
Write a complete program to generate a username based on a user's first and last name.
Part One: Get a Valid First and Last Name
ask the user for and read in their first and last name
use a loop to validate the first name: it must be at least one character long and it must start with a letter
use a loop to validate the last name: it must not contain any spaces
Hint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace.
Part Two: Generate a Username
generate a two-digit random number (i.e., a random number between 10 and 99, inclusive)
create a username that is the following data concatenated:
the first letter of their first name in lower case
the first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last name
the two-digit number
output the username to the user

3. Write a program that deliberately contains an endless or infinite while loop. The loop should generate multiplication questions with single digit random integers. Users can answer the questions and get immediate feedback. After each question, the user should be able to stop the questions and get an overall result. See Example Output.
Example Output

Want more questions y or n ? y
What is 8 * 5 ? 40
Correct. Nice work!
Want more questions y or n ? y
What is 5 * 5 ? 25
Correct. Nice work!
Want more questions y or n ? y
What is 8 * 9 ? 66
Incorrect. The product is 72

- eeringQ&A LibraryCreate a java program 1. Broken Record Looping strings works like playing a broken record – it repeats something over and over again. But what's great about loops is that we can define as to how many times it will repeat something with proper code, and that's what we're about to do now using while() loops. Instructions Scan a positive integer and store it in a variable. Using while() loop, repeatedly print out "CodeChum is awesome" for the same number of times as that of the inputted integer. Each outputted string must be separated in new lines. Don't forget to make an increment variable that will increase its value per iteration so as to not encounter a forever loop and have errors, okay? Input Format A line containing an integer.

Select one: a. int index = 0; do{ if(numbers[index]%2 == 1) System.out.println(numbers[index]+" is an odd number."); index++;}while(index < numbers.length); b. for(int a=0 ;a < numbers.length; a +=2){ System.out.println(numbers[a]+" is an odd number.") } c. for(int num:numbers){ if(num%2 == 1) System.out.println(num+" is an odd number.") } d. int index = 0; while(index < numbers.length){ if(numbers[index]%2 == 1) System.out.println(numbers[index]+" is an odd number."); index++; } CLEAR MY CHOICEarrow_forwardJAVA Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. Write a Java program that takes integer inputs N (where N >= 2 ) from the user until the user input is 0 (zero is the sentinel value) and check if the user input value is a prime number or not. Use nested loops. Sample Input and output: Enter a number > 2 Output: prime Enter a number > 11 Output: prime Enter a number > 10 Output: not prime Enter a number > 9 Output: not prime Enter a number > 23 Output: prime Enter a number > 0 Output: Loop ends.

But the one last time was too lengthy to look at, so I just want to view it in a shorter but still readable format. You okay with this task? Instructions: Print out all numbers from 1 to 100 that is divisible by 3 using a for loop just like the last problem, but this time, with each number only separated by the space like that of the sample output. Output A line containing integers divisible by 3 separated by a space. 3·6·9·12·15·18·21·24...arrow_forwardJAVA LANGUAGE PLS THANK YOU 1. Squares by CodeChum Admin Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this! Instructions: Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line. Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition. Input Multiple lines containing an integer. 2 6 0 Output Multiple lines containing an integer. 4 36 0arrow_forwardUse nested loop in Java language. This program asks the user to enter an integer from 3 to 9* and prints a pattern of numbers based on that number.* For example, given the number 4 as input, the output would be:* * 1** 21** 321** 4321** 321** 21** 1** * Print a newline between the prompt and the beginning of the stars.* Note that no input validation is required.arrow_forward

Do not write the code in multiple programs. All the 3 methods should be written in 1 program. Write a java program calls the following methods: printStars(): Takes an int (n) as parameter and prints n stars (*) using for loop. Multiples(): Takes an int (n) as parameter and prints first 10 multiples n in a single line using for loop. hasAnEvenDigit: Takes an int (n) as parameter and returns whether n has at least one digit whose value is even. Return true if the number has at least one even digit else false if none of the digits are even. For example, the call hasAnEvenDigit(33267) should return true and hasAnEvenDigit(7591) should return false. [Hint: n%10 returns the last digit and n/10 returns everything except the last digit]arrow_forwardIn Java A while loop reads integers from input. Write an expression that executes the while loop until a positive integer is read from input. Ex: If the input is -20 -43 -25 -22 15, then the output is:User entered -20User entered -43User entered -25User entered -22Loop terminated while () {arrow_forward
