NullPointerException with read properties file in java

Question

When load the properties file I get a java.lang.NullPointerException

This is a simple java swing application, try to read the properties file with following code get java.lang.NullPointerException:

InputStream inputStream;
Properties properties;

inputStream = new FileInputStream("C:/Config/config.properties");
properties.load(inputStream);

Which line throws the exception? What variable was null then? How could it be that? — Thorbjørn Ravn Andersen, Jan 20 '19 at 09:32

You are missing creating a properties instance:

Properties properties = new Properties();

There is some basic understanding missing here which answering the question directly will not help. – Thorbjørn Ravn Andersen Jan 20 '19 at 09:34
