Create a .properties file in java

import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
 
public class App 
{
    public static void main( String[] args )
    {
     Properties prop = new Properties();
 
     try {
      //set the properties value
      prop.setProperty("database", "localhost");
      prop.setProperty("dbuser", "Harit");
      prop.setProperty("dbpassword", "password");
 
      //save properties to project root folder
      prop.store(new FileOutputStream("config.properties"), null);
 
     } catch (IOException ex) {
      ex.printStackTrace();
        }
    }
}
