Trace and document every step of execution of the following program:
public class Trace {
public static void main(String[] args) { int[] num = {1, 3, 6, 9, 12 };
for (int i = 4; i >= 0; i--) { num[i] +=1; } num[0] *=num[4]; } }
In Java trace the table for a while loop
public class Main { public static void main(String[] args) { // Question 2 j = 30; x=5; for (int i=1;i<=2;i++) { while (j > 20) { j=j-x*i; ++x; }// end of while }// end of for
j

j<=2
j>20
Q27 for java programing:
public static void main(String[] args) {
Dog[] dogs = { new Dog(), new Dog()};
for(int i = 0 ; i < dogs.length; i++)
dogs[i].wo();
Cat[] cats = { new Cat(),new Cat(),new Cat()};
for(int i = 0 ; i < cats.length; i++)
cats[i].me();
System.out.print(Dog.getCount()+" woofs and");
System.out.println(Cat.getCount()+" mews");
System.out.println("=====>>>"+decision()); }
class Counter
{ private static int count;
public static void inc() { count++;}
public static int getCount() {return count;}
}
class Dog extends Counter{
public Dog(){}
public void wo(){inc();}
}
class Cat extends Counter{
public Cat(){}
public void me( ){inc();}
}
The Correct answer:
public static void main(String[] args) {
Dog[] dogs = { new Dog(), new Dog()};
for(int i = 0 ; i < dogs.length; i++)
dogs[i].wo();
Cat[] cats = { new…
