I declared two Strings as below and initialise them as blank but in output one vale is blank and other show null.

   String insert_brand_from_table="",insert_model_from_table="";
   System.out.println("brand:  "+insert_brand_from_table);
   System.out.println("model:  "+insert_model_from_table);

But output is :

   brand:  
   model:  null

Now the null value of model showing null pointer exception error when i try to save model as blank into database.

    why the fx tag? It's completely unrelated ... changed to java. Anyway, it's missing details to be answerable and it's a duplicate. Have a look at the referenced QA to get an idea on how to solve it. When still stuck, come back with a [mcve] demonstrating the problem – kleopatra Oct 01 '20 at 10:54

    Tried it in a console application and it works as expected! Both of them are empty strings, none of them is written as null – Onur Baştürk Oct 01 '20 at 11:00
