     Student record1 = new Student("Aaron Ang", 3.25);
     Student record2 = new Student("Bobby Bok", 2.11);

public class Student {
	
	private String name;
    private double gpa;
    
    public Student(String name, double gpa) {
    	this.name = name;
        this.gpa = gpa;
    }
    
    public void setGpa(double newGpa){gpa = newGpa;}
    public double getGpa(){return gpa;}
    
    public void setFirstName(String newName){name = newName;}    
    public String getFirstName(){return name;}
    
    
    public String toString(){
        String s = "Student Records \n";
        s += "================================\n\n";
        s += "\nName: " + getFirstName();
         s += "\nGPA: " + getGpa();
        return s;
    }
    
    
}

I assume that you want to know the usage of getter methods..
You can call the getter methods like below..

Student record1 = new Student("Aaron Ang", 3.25);
System.out.println(record1.getFirstName());  

this will print "Aaron Ang" on console.
Is that you want???

I guess you want to extract the First Name from the Full Name?

I would advise you to create a getter/setter for both firstname and lastname. Because if the first or last name contains a space then you won't be able to separate them.

Hi Nitesh

i'm suppose to create an array to store 8 students, user will need to input data 8 student data - name & gpa only
Each element reference to Student class.

it should print "Aaron" as the first name when e.g: "Aaron Carter" & calculate the average gpa is input.



Thanks

To extract the First Name from the Full Name, you can have a look on the Java String API.
To calculate the average GPA, it is just simple maths. You should have no problem. But If you do, post your code and we would help.
