Trace the exact output of the following programs by running them in a java compiler. (ps I don't have laptop to run this codes pls help thankyou)? 1. class Apple { String color = "red"; } public class SampleReference1 { public static void main(String[] args) { Apple apple = new Apple(); System.out.println(apple.color); changeApple(apple); System.out.println(apple.color); } public static void changeApple(Apple apple) { apple.color = "green"; } } 2. class ThisKeyword { int a; int b; void getData(int a, int b) { a = 3; b = 2; } void showData() { System.out.println("Value of Variable A is: " + a); System.out.println("Value of Variable B is: " + b); } } public class SampleReference2 { public static void main(String[] args) { ThisKeyword T = new ThisKeyword(); T.getData(4, 5); T.showData(); } } 3. class Demo_class { int int_variable = 10; } public class SampleReference3 { public static void main(String[] args) { Demo_class a = new Demo_class(); Demo_class b = a; b.int_variable = 20; System.out.println("the value of int_variable is " + a.int_variable); } }

Trace the exact output of the following programs by running them in a java compiler. (ps I don't have laptop to run this codes pls help thankyou)?
1. class Apple
{
String color = "red";
}
public class SampleReference1 {
public static void main(String[] args) {
Apple apple = new Apple();
System.out.println(apple.color);
changeApple(apple);
System.out.println(apple.color);
}
public static void changeApple(Apple apple)
{
apple.color = "green";
}
}
2. class ThisKeyword
{
int a;
int b;
void getData(int a, int b)
{
a = 3;
b = 2;
}
void showData()
{
System.out.println("Value of Variable A is: " + a);
System.out.println("Value of Variable B is: " + b);
}
}
public class SampleReference2 {
public static void main(String[] args) {
ThisKeyword T = new ThisKeyword();
T.getData(4, 5);
T.showData();
}
}
3. class Demo_class
{
int int_variable = 10;
}
public class SampleReference3 {
public static void main(String[] args) {
Demo_class a = new Demo_class();
Demo_class b = a;
b.int_variable = 20;
System.out.println("the value of int_variable is " + a.int_variable);
}
}
