The ID (idNum) is then set to 9999 by course students by using the student data class's setID mutator function.
What is the JAVA program?The Person Data class's print () function is then invoked using the course student object. There are two print statements in this approach, i.e.
"Name:" + lastname; System.out.print;
Age: ageYears + System.out.print(" Age: ");
So, the output screen displays these two statements. They show the person's name and age, i.e. Smith and 20 are separated by a comma.
The ID must also be displayed after that, thus we use the following phrase: course student.getID() + "ID: "; System.out.println;
The getID accessor method of the Student Data class is used in the print line above in order to obtain the ID and display it on the screen.
Therefore, as a result, the following is the program's output: Smith, 20 years old, has ID 9999.

What is a class?For object-oriented programming languages, the fundamental building blocks are the class and the object. To create an object (computer science), a programmer uses an object-oriented programming language and writes a class with a predetermined structure. It specifies a group of traits and operations that apply to all objects of a particular type.
For illustration, a class might be a car, with fields for color, four tire fields, and driving. A truck, which has some similarities to but differs from a car in certain ways, could be another related class.

The name of an array, without any brackets, acts as a(n) ______to the starting address of the array.
The name of an array, without any brackets, acts as a constant pointer to the starting address of the array. It represents the memory location of the first element and allows efficient access and manipulation of array elements.
In programming, an array is a collection of elements of the same data type stored in contiguous memory locations. When an array is declared, the name of the array serves as a constant pointer that points to the memory address of the first element in the array. This memory address is also known as the "starting address" or "base address" of the array.
For example, in C or C++:
```c
int numbers[5] = {1, 2, 3, 4, 5};
```
Here, `numbers` is the name of the array. It represents the starting address of the first element, which is `1`. Since all elements in the array are of the same data type (in this case, integers), the memory locations are contiguous, allowing for efficient access and manipulation of array elements.
Using the array name without brackets in an expression will result in the address of the first element. For instance:
```c
int *ptr = numbers; // 'numbers' is implicitly converted to a pointer to the first element
```
Now, `ptr` holds the address of the first element in the `numbers` array.
When performing arithmetic with the array name or pointer, keep in mind that the size of the data type is considered. For example:
```c
int thirdElement = *(numbers + 2); // Access the value of the third element (3)
```
In this expression, `numbers + 2` calculates the address of the third element, and `*` dereferences that address to access the value.

A local variable declared inside of a function can have the same name as a global variable.
What is meant by Global variable ?As the name suggests, global variables are variables that are available everywhere in the application. They are stored in memory for the duration of the programme after being declared. This implies that they are changeable at any time by any function and may have an impact on the entire programme.
Global variables are those that have been declared outside of the specified function. These are not restricted to a particular function, therefore any available function can be used to access and alter global variables.
Global variables are those that are produced outside of a function, like in all of the aforementioned cases. Everyone can use global variables, both inside and outside of functions.
