Kotlin Standard Library Cookbook

How to do it...

1.  Import the File.separator constant and assign an alias to it:

import java.io.File.separator as SEPARATOR

2. Declare a String storing a path to the file we are going to read:

val filePahtName = "src${SEPARATOR}main${SEPARATOR}resources${SEPARATOR}file1.txt"

3. Instantiate a FileInputStream for the file1.txt file:

val filePahtName = "src${SEPARATOR}main${SEPARATOR}resources${SEPARATOR}file1.txt"val stream = File(filePahtName).inputStream()

4. Read the bytes from the stream inside the use() function:

val fileName = "src${SEPARATOR}main${SEPARATOR}resources${SEPARATOR}file1.txt"val stream = File(fileName).inputStream()stream.use {    it.readBytes().also { println(String(it)) }}
