- First code is top, second code is on bottom. This is for Java. What makes these two codes different? (a) If x = 3, what will the first (code) print out? (b) If x = 3, what will the second (code) print out? (c)If x = 1, what will the first (code) print out? (d) If x = 1, what will the second (code) print out?float f = 12.5F; int i = (int)f; System.out.println("f is " + f); System.out.println("i is " + i);Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);

Then read input from the user as a string. Attempt to convert it to an integer using the "Integer.parseInt" method. If the process throws a "NumberFormatExeption", print an appropriate error message and prompt the user for the number again. Continue prompting and reading in number until 10 valid integers have been read Print "The average is" and then print the average of the 10 numbers Code: import java.util.Scanner; public class Lab1MainClass { public static final int VALUES_TO_READ = 10; public static void main(String[] args) { // local variables int[] values = new int [VALUES_TO_READ]; double average; Scanner scan = new Scanner(System.in); int values Read = 0; // how many numbers the user has given us, a count of where we are String userInput; // read…
