First, you will debug the Paint1 class so that no errors remain and all calculations work correctly by completing the following: o Find and fix the three errors in the given code. • Use the following sample input values to test your program. If you have found and fixed all the errors, your output should exactly match the sample. Input: 30 25 Output: Wall area: 750.0 square feet Paint needed: 2.142857142857143 gallons Tip: When you run your program in Eclipse, it will prompt you to enter input in the Console window. If you cannot find this window, go to Window, then Show View, then Console. Next, you will add loops to validate all user input and handle exceptions so that code passes all test cases by completing the following: • Review the code, looking for the two code blocks where user input is required. • Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled. • Use the two following sample sets of input to test your program.…
Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text. Ex: If the input is: Hello there Неу quit the output is: ereht olleH yeH
AJ * New + Countdown.java 1 import java.util.Scanner; 2 3 public class Countdown 4- { 5 6- 7 8 9 10 12345678 19 20 11 19} 20 public static void main(String args) { // Start here } public static String countdown(int number) { } // Base case - return Blastoff! // Recursive call Submit + Continue Save Output Test Cases Docs Assignment Sample Outputs Enter starting number: 7 7 5 31 Blastoff! Grade For this exercise, you are going to write a recursive function that counts down by twos to a Blastoff! Enter starting number: 10 10 8 6 4 2 Blastoff! More Your recursive function will not actually print. It will return a String that can be printed from the main function. Each recursive call will add on to that string. In your main function, prompt the user for a starting value, then print the results.
in java Write a for loop that prints: 1 2 … lastNumber Ex: If the input is: 4 the output is: 1 2 3 4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 import java.util.Scanner; public class ForLoops { publicstaticvoidmain (String [] args) { intlastNumber; inti; Scannerinput=newScanner(System.in); lastNumber=input.nextInt(); for (/* Your code goes here */) { System.out.print(i+" "); } } }

In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. An example of the program is shown below: Enter a number between 1 and 20 >> 5 5 4 3 2 1 Blastoff! Depending on the value assigned to the…
ntegers outerRange and innerRange are read from input. Complete the outer while loop so the inner loop executes (outerRange + 1) * innerRange times. Ex: If the input is 6 5, then the output is: Inner loop ran 35 times import java.util.Scanner; public class LoopCounter { public static void main (String[] args) { Scanner scnr = new Scanner(System.in); int outerRange; int innerRange; int count; int i; int j; outerRange = scnr.nextInt(); innerRange = scnr.nextInt(); count = 0; i = 0; while (/* Your code goes here */) { j = 0; while (j < innerRange) { ++count; ++j; } ++i; } System.out.println("Inner loop ran " + count + " times"); } }
