First, we’ll learn how to load a file from the classpath, a URL, or from a JAR file using standard Java classes. Second, we’ll see how to read the content withBufferedReader,Scanner,StreamTokenizer,DataInputStream,SequenceInputStream,andFileChannel. We will also discuss how to read a U...

To demonstrate the various examples below, I have placed a file with matching name in different locations and I will show to load each one of them. ResourceLoaderWithResourceLoaderAware.javais written as below which print the content of loaded resource file into console. ...
Here, we’re just loading the file metadata, the large file content isn’t loaded into memory yet. For our example, we’ve got a constant fixed size. In practical use cases, thismaxSizeOfSplitFilesvalue can be dynamically read and changed as per application need. ...
