Question

I am currently working on a project using Objectdb and Im using NetBeans.
I want to have a myString method that can appear this message :
Variable type is int.
when im calling the object Driver from another main class
[

 import javax.persistence.*;
 import java.util.*;
 //import javax.jdo.*;
 import java.sql.*;

 public class Main { 

public static void Element(Object obj){
    System.out.println(obj);
}//end method Element

 public static void main(String[] args) {

 Element(Driver);

}//end main

]
Of course I don’t want to type exactly this thing so I can print it,
but instead I want a method that can return int if its an integer, String if it is String etc.
When it come to a String variable it is ok.
But when I have an integer it shows me the message “int cannot be dereferenced” so the compiler won’t pass this.
Is this a way to work it around correctly?
This is importart so thanks in advance.

import javax.persistence.*;
import java.util.*;

@Entity
public class Driver{    

@Id 
    private int Driverid;

    public void setDriverid(int Driverid) {
        this.Driverid= Driverid;
    }

    public int getDriverid() {
        return Driverid;
    }

public Driver(int getDriverid){
        this.Driverid=Driverid; 
}

public String toString() {
        return  "Variable type is " + Driverid.getClass.getSimpleName() + "." ;
}//end toString

}//end class Driver

Answer 1

Try with using the Integer class instead of int. int is a primitive type, Integer is not.
