Write a class definition of a class named Value with the following: a boolean instance variable named modified, initialized to false an int instance variable named val a constructor accepting a single parameter whose value is assigned to the instance variable val a method getVal that returns the current value of the instance variable val a method setVal that accepts a single parameter, assigns its value to val, and sets the modified instance variable to true a boolean method, wasModified that returns true if setVal was ever called.

The class definition to this question can be given as:

Class definition:

public class Value / /define class value.

{

private boolean modified = false; / /define variable modified.

private int val; / /define variable.

Value (int i) / /parameterized constructor

{

val = i; / /holds parameter value.

}

public int getVal () / /define method getVal.

{

return val;

}

public void setVal (int i) / /define method setVal

{

val = i; / /holds parameter value

modified = true; / /change boolean variable value.

}

public boolean wasModified () / /define method wasModified.

{

return modified; / /return value.

}

}

Explanation:

The description of the above class definition as follows:

Firstly we define a class that is "value" inside a class we define two variable that is "modified and val". Where modified is a boolean variable that holds boolean value true or false and val is an integer variable that holds an integer value. Inside the class, we define parameterized constructor in this constructor we pass an integer parameter that is "i" inside this constructor we use the val variable for hold i variable value. Then we define three functions that are "getVal, setVal, and wasModified". The getVal () function is used for return value. The setVal () function uses an integer parameter that is "i" this function holds value in variable i in val variable and change value of the modified variable that is "true". The wasModified () function is used to return modified variable value.
