Only "con" in /data/data in android device monitor

I am new to SQlite databases. I am trying to view my databse but when ever I open the Android Device Monitor and go to Data/Data/ I only find folders with name 'con'; I'm working on an EMULATOR. Please help me as I've searched & 've tried several solutions like restarting and reaching adb shell but nothing worked......here is my databasehelper class code

package com.example.maria.sqlapp;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

/**
* Created by Maria on 11/23/2015.
*/
public class Databasehelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME= "student.db";
public static final String TABLE_NAME= "student_data";

public static final String COL_1= "ID";
public static final String COL_2= "NAME";
public static final String COL_3= "SURNAME";
public static final String COL_4= "MARKS";

public Databasehelper(Context context) {
    super(context, DATABASE_NAME, null, 1);
    SQLiteDatabase sqLiteDatabase = this.getReadableDatabase();
}

@Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {


        String query = "CREATE TABLE " + TABLE_NAME + "(" +
                COL_1 + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                COL_2 + " TEXT, " +
                COL_3 + " TEXT, " +
                COL_4 + " INTEGER " +
                ");";
    sqLiteDatabase.execSQL(query);
    }

   /* sqLiteDatabase.execSQL("CREATE TABLE" + TABLE_NAME + "("
            +COL_1 + "INTEGER PRIMARY KEY AUTOINCREMENT, "
            +COL_2 +" TEXT, "
            +COL_3 +" TEXT, "
            +COL_4 +"INTEGER);");
   }
*/



@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
    onCreate(sqLiteDatabase);
}


/*@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS"+TABLE_NAME);
    onCreate(sqLiteDatabase);
}*/
}
