ISP-Java Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. For coding simplicity, output a space after every integer, including the last. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first.
A parking lot charges $3 per hour for the first 10 hours of a 24 hour period. There is no further charge starting at the 11th hour and ending at the 24th hour. The charge for a full 24 hour period is therefore $30. The same pattern applies for periods longer than 24 hours. Write a program to calculate the cost in dollars, given the number of hours that the parking lot was used. public class Parking { } public static void main(String[] args) { } // Change hours to get the answer for the those number of hours. int hours = 25; } int result = cost(hours); System.out.println(result); public static int cost(int hours) { int result = 0; // Write your code within the body of this method. return result;
Write code that prints: countNum ... 21 Print a newline after each number.

Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}
Extend to cast the double to an integer, and output that integer.

Write code that outputs variable numDogs as follows. End with a newline. Ex: If the input is: 3 the output is: Dogs: 3 import java.util.Scanner; public class OutputTest { public static void main (String [] args) { int numDogs; // Our tests will run your program with input 3, then run again with input 6. // Your program should work for any input, though. Scanner scnr = new Scanner(System.in); numDogs = scnr.nextInt(); System.out.println("Dogs: 3"); }} I cant seem to get the correct answer no matter what I try. What am I missing?
1. Write a program that takes three numbers (a,b,c) from the user as input and finds the median of the three. The program has a method called median that takes 3 numbers as the parameter and returns the median. Use if-then-else statements to find the median. You can assume the three numbers are not the same. Sample Example: Enter 3 numbers 10 13 The median is 10 public class Median{ public static void main(String[] args){ Scanner input = new int a = int b = int c =
