1- Create class Student that has the following data: id(int), name(string), gpa (double), generate constructor, setter/getter and toString methods.
2- Create class Car that has the following data: plateNo(int), brand(String), generate constructor, setter/getter and toString methods.
3- Create a new class, call it GM_Test, in the class create
a- generic method called swapFirstLast, it receives a generic type array, and swaps the last element in the array with the first one.
b- generic method called reverse, it receives a generic type array, and reverse the order of the elements in the array.
C- Generic method shift that receives an a generic type array and shifts its element one position to the left as depicted by the following figure
So after calling the method, the above array will be as follows
d- Generic method print that receives a generic type array and prints its elements.
e- Create main method, and in the method create the following arrays and fill them with elements: Array of students (3 elements) Array of accounts (4 elements)
f- In the main method, call the methods in a,b,c on the array of students and accounts. Each time, print the array before you call the method, then print it after calling the method to see its effects.
g- Create the following arrays:
int intArray[]={4,1,7,9);
char chArray[]={'a','b','c','d'};
call the methods in a,b,c on the array of intArray and chArray. Each time, print the array before you call the method, then print it after calling the method to see its effects.

Exercise 1
1)
Student class
public class Student {
private int id;
private String name;
private double gpa;
public Student(int id, String name, double gpa) {
this.id = id;
this.name = name;
this.gpa = gpa;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getGpa() {
return gpa;
}
public void setGpa(double gpa) {
this.gpa = gpa;
}

@Override
public String toString() {
return "Student{" + "Id=" + id + ", Name=" + name + ", GPA=" + gpa + '}';
}


}
2)
Car class
