Java read text classes. We can use the following Java classes to read text files in Java. java.io.FileReader java.nio.file.Files java.util.Scanner java.io.InputStreamReader com.google.common.io.Files Read text file with FileReader. FileReader is a class used for reading character files. It reads text from character files using a default

In this example, we will learn to load a file as an input stream using the FileInputStream class in Java. Certification courses in Python, Java, SQL, HTML, CSS, JavaScript and DSA. Try Programiz PRO!

Note We can also use both BufferReader and Scanner to read a text file line by line in Java. Then Java SE 8 introduces another Stream class java.util.stream.Stream which provides a lazy and more efficient way to read a file. Let us discuss each of the above methods to a deeper depth and most importantly by implementing them via a clean java

main INFO org.baeldung.java.CoreJavaIoUnitTest - Total Memory 2666 Mb main INFO org.baeldung.java.CoreJavaIoUnitTest - Free Memory 490 Mb This means that about 2.1 Gb of memory are consumed by the process - the reason is simple - the lines of the file are all being stored in memory now.

Reading a text file into a string. If you want to load the contents of a text file into a String, use - since Java 11 - the Files.readString method as follows String fileName String text Files.readStringPath.offileName Code language Java java

During Java application development, we need to read the contents of a file into a string in many situations such as processing configuration files, parsing data, or handling text-based resources. In this Java tutorial, we will explore different ways to read a text file into String in Java from traditional BufferedReader, new APIs in Java 8 and
