- People find it easier to read time in hours, minutes, and seconds rather than just seconds. Write a program that reads in seconds as input, and outputs the time in hours, minutes, and seconds. Ex: If the input is: 4000 the output is: Hours: 1 Minutes: 6 Seconds: 40Consider the GameOfLife class public class GameOfLife { private BooleanProperty[][] cells; public GameOfLife() { cells = new BooleanProperty[10][10]; for (int x = 0; x < 10; x++) { for (int y = 0; y < 10; y++) { cells[x][y] = new SimpleBooleanProperty(); public void ensureAlive(int x, int y) { cells[x][y].set(true); public void ensureDead(int x, int y) { cells[x][y]•set(false); public boolean isAlive(int x, int y) { return cells[x][y]•get(); } a. Identify one code smell in this program. b. Identify and explain the most pertinent (problematic) design smell in this program.public class ArraySection { static void arraySection(int a[], int b[]) { int k = 0; int [] c = new int[a.length]; for(int i = 0; i < a.length; i++) { for(int j = 0; j < b.length; j++) if(a[i] == b[j]) c[k++] = a[i]; } for(int i = 0; i < k; i++) System.out.println(c[i]); System.out.println(); } public static void main(String[] args) { int a[] = { 1, 2, 3, 4, 5 }; int b[] = { 0, 2, 4,5 }; arraySection(a,b); }} Calculate the algorithm step number and algorithm time complexity of the above program?

- import javax.swing.JOptionPane; public class Addition{public static void main( String args[] ){for (int i = 0; i < 10; i++) {String Number = JOptionPane.showInputDialog( "Enter a number" );int number = Integer.parseInt( Number );int sum = number;JOptionPane.showMessageDialog( null, "The sum is " + sum,"Sum of 10 numbers", JOptionPane.PLAIN_MESSAGE );}}} I want to add the number that was entered but I don't know how to do that. Do you know how to add the entered number?Exercise 2: Consider the following class: public class Sequence { private ArrayList values; public Sequence() { values = new ArrayList(); } public void add(int n) { values.add(n); } public String toString() { return values.toString(); } } Add a method public Sequence merge(Sequence other) that merges two sequences, alternating ele- ments from both sequences. If one sequence is shorter than the other, then alternate as long as you can and then append the remaining elements from the longer sequence. For example, if a is 1 4 9 16 and b is 9 7 4 9 11 then a.merge(b) returns the sequence 1 9 4 7 9 4 16 9 11 without modifying a or b.import java.awt.*; public class TestRectangle {public static void main(String[] args) {Rectangle r1 = new Rectangle(5, 4, 10, 17);Rectangle r2 = new Rectangle(10, 10, 20, 3);Rectangle r3 = new Rectangle(0, 1, 12, 15);Rectangle r4 = new Rectangle(10, 10, 20, 3);System.out.println("r1 = " + r1);System.out.println("r2 = " + r2);System.out.println("r3 = " + r3);System.out.println("r2 equals r1?
