Question

Student is a class that has the following instance variables: name (a String), yearInSchool (an int), and gpa (a double). Write a constructor for the Student class that takes parameters for these instance variables as initial values of the variables. (in Java)

Answer 1

class Student{

//Instance Variables

String name;

int yearInSchool;

double gpa;

//parameterized constructor

//"this" is pointer to access instance variable of same class

public Student(String name,int yearInSchool,double gpa){

this.name=name;

this.yearInSchool=yearInSchool;

this.gpa=gpa;

}

//display function to display the initialized data

void display(){

System.out.println(name);

System.out.println(yearInSchool);

System.out.println(gpa);

}

//Main Function

public static void main(String args[]){

//Student class object is created and passing parameter to constructor of Student class.

Student st=new Student("ABcd",8,4.8);

st.display();

}

}
