TASK 3. Console Input and Output. Review Scanner class and its methods, Implement the following code, make sure it runs without errors. 1 package 1lessons; 3 import java.util.Scanner; 4 5 public class ReportSum3 { public static void main(String args[]) { Scanner sc = new Scanner(System. in); 60 7 8 // Prompt the user to enter the first integer System.out.println("Enter the value for 'a' and press Enter: "); int a = sc.nextInt(); // Prompt the user to enter the second integer System.out.println("Enter the value for 'b' and press Enter: "); int b = sc.nextInt(); 10 11 12 13 14 15 16 17 18 19 20 21 22 } //Close the Scanner. It's a good practice to release the resource that was acquired sc.close(); // Display the result System.out.printf( "Provided Integers: %4d and %4d, the total is %5d\n", a, b, (a + b)); } To simplify the task, we came out with the idea to use Methods. Implement a method to add two integers.
Task 4: public class Palindrome TestWrapper final String isMsq = "IS a palindrome"; final String isNotMsq- " is NOT a palindrome"; public static void main(String args[]) new PalindromeTestWrapper(); public PalindromeTestWrapper() // your code here 1 public boolean isPalindrome ( Strings ) 1 // your code here Using the code defined above, complete the isPalindrome method so that it returns true if s is a palindrome and false if it isn't. You must use a stack in your solution algorithm.

Look at this program: int main(){ int x = 4; displayMessage(); return 0;}void displayMessage(){ for(int x = 1; x <= 100; x++) cout << "I love computer science" << endl;} What will the output be? Answers: Nothing. It won't compile because you can't define the variable x inside a loop heading. Nothing. It won't compile because the displayMessage function is being called before it has been defined "I love computer science" 100 times "I love computer science" Nothing. It won't compile because you can't call a void metho
Java Programming: The program will figure out a number chosen by a user. Ask user to think of a number from 1 to 100. The program will make guesses and the user will tell the program to guess higher (h) or lower (l). Sample run of the program might look like below : Guess a number from 1 to 100. (here, the user is thinking of 81) Is it 50? (h/l/c): h Is it 75? (h/l/c): h Is it 88? (h/l/c): l Is it 81? (h/l/c): c Great! Do you want to play again? (y/n): y Guess a number from 1 to 100. (here the user is thinking 37) Is it 50? (h/l/c): l Is it 25? (h/l/c): h Is it 37? (h/l/c): c Great! Do you want to play again? (y/n): n our program should implement the binary search algorithm. Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying “higher” On the second…
