After we have written the definition of the methods of the class MyClass, what is the output of the following code? myObject1.printX( ); myObject1.incrementCount( ); MyClass.incrementCount( ); myObject1.printCount( ); myObject2.printCount( ); myObject2.printX( );: myObject1.setX(14); myObject1.incrementCount( ); myObject1.printX(); myObject1.printCount( ); myObject2.printCount( );

JAVA

Certainly! Here's the transcription of the image text suitable for an educational website: --- **Problem Statement:** Assume that `myObject1` and `myObject2` are declared as in parts (d) and (e). After we have written the definition of the methods of the class `MyClass`, what is the output of the following code? ```java myObject1.printX(); myObject1.incrementCount(); MyClass.incrementCount(); myObject1.printCount(); myObject2.printCount(); myObject2.printX(); myObject1.setX(14); myObject1.incrementCount(); myObject1.printX(); myObject1.printCount(); myObject2.printCount(); ``` **Explanation:** The code snippet involves two objects, `myObject1` and `myObject2`, of a class called `MyClass`. The methods used include: - `printX()`: Presumably prints the value of a variable `X`. - `incrementCount()`: Increments a count variable (details of the type and scope are assumed from usage). - `setX(int value)`: Sets the value of `X`. - `printCount()`: Presumably prints the current count. The exact output depends on the class definitions and initial values, which are set in parts (d) and (e).

```java 2. Consider the following definition of the class MyClass. public class MyClass { private int x; private static int count; // default constructor public MyClass() { … } // constructor with a parameter public MyClass(int a) { … } // method to set the value of x public void setX(int a) { … } // method to output x public void printX() { … } // method to output count public static void printCount() { … } // method to increment count public static void incrementCount() { … } } ``` **Explanation:** - The class `MyClass` contains two private variables: `int x` and `static int count`. - It has a default constructor and a constructor with one parameter. - `setX(int a)` is a method to set the value of `x`. - `printX()` is a method to output the current value of `x`. - `printCount()` is a static method to output the current value of `count`. - `incrementCount()` is a static method used to increment `count`.
