Getting null pointer exception In FILE class

Question

File file = new File(getClass().getResource(filePath + "/createFile.xml").toURI());

I get an error of java.lang.NullPointerException in above line. Here filePath is string variable in which I have set my directory path from where I want to read file.

Why don't you write the code simply just like this: new File(filePath+"/createFile.xml");? — ntalbs

@ntalbs You have to use getResource if you want to load a file from a jar. For normal files your way is much cleaner. — Thirler

I have try like "new File(filePath+"/createFile.xml");" and It's read content successfully, but when I pass this data, I got same errorr in last line of below code. File file1 = new File(filePath + "\\createFile.xml"); Container container = importController.importFile(file1); container.getLoader().setEdgeDefault(EdgeDefault.DIRECTED); — user3902398

Class.getResource() will return null when the resource was not found. You always should test for that before using it.
