Question

i have problem with printing the array after reading it. After printing, the address of memory is printed, not value of the array. What can i do for that ?

public class MyClass
{
     Student St = new Student();

     Student[]Array1 = new Student[10];


     void AddList()
     {

            Scanner Scan = new Scanner(System.in);

            for (int i=0; i<Array1.length & i<ArrayF1.length; i++)
            {
                System.out.println("Enter Student NAME Number " + (i+1) + ":");
                Array1[i] = new Student();
                Array1[i].setName(Scan.next());


                //System.out.println("Enter Student MARK Number " + (i+1) + ":");
                //St.setMark(Scan.nextFloat());
            }

    }

this is my print method. The result of print is like this

(studentproject.Student@1a758cb)

 void PrintList()
 {

            for (int i=0; i<Array1.length; i++)
            {

                System.out.println(Array1[i]);

            }
 }

this is my Student Class that i have all my setter and getter method on that … So i have 3 Class how can i work with this 3 class and in one of them get the data and in another print the Mark data and in third class print the Student Name data … how can i do that … i do some code but i dont know is it correct or not … thanks for your help …

public class Student
{
private String Name;
private float Mark;

/**
 * @return the Name
 */
public String getName() {
    return Name;
}

/**
 * @param Name the Name to set
 */
public void setName(String Name) {
    this.Name = Name;
}

/**
 * @return the Mark
 */
public float getMark() {
    return Mark;
}

/**
 * @param Mark the Mark to set
 */
public void setMark(float Mark) {
    this.Mark = Mark;
}

}

Just override the toString() method in Student class, and return the appropriate string you want to get printed when you print an instance.

It may look like: –

@Override
public String toString() {
    return "Name: " + studentName;
}

Currently, the default implementation of toString() method of Object class is invoked, and what you are seeing is the format returned from that method, which is of the form – Type@hashCode
