Jon Andrew :
I am doing some coding in Java, but it doesn't work:
import java.util.Scanner;
import java.util.Arrays;
public class Main {
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
String [] studentId = new String [3];
Student name;
for (int i = 0; i < 3; i++)
{
System.out.print("Enter Name => ");
name = new Student(input.next());
studentId[i] = name.toString();
}
for (int i = 0; i < 3; i++)
{
System.out.println(studentId[i]);
}
}
}
public class Student
{
private static int studentId;
private String name;
public Student(String name)
{
this.name=name;
setStudentId(studentId++);
}
public int getStudentId()
{
return studentId;
}
public void setStudentId(int studentId)
{
this.studentId = studentId;
}
@Override
public String toString()
{
return (this.studentId +" "+ "student is "+ " " + "(" + this.studentId + ")"+ this.name);
}
}
I need to auto-increment the Id when a new entry is created. I try everything but still cant increased it.
PhuLuong :
In constructor it should be:
{
public Student(String name)
{
this.name=name;
setStudentId(studentId + 1);
}
}
