Basic File Manipulation With Java
Accessing files with Java is easy. With this easy to follow tutorial you will learn how to perform basic file operations in Java. Reading, writing, appending, and random file access are covered. Along with an introduction to file locking.
Thank you for taking the time to report an issue.

Java comes with many handy I/O classes to support the input and output through bytes stream and file system. Here’s a list of the Java I/O examples including file, temporary file and directory manipulation, encoding, serialized and also compression with zip or Gzip.
This is a simple Java Configuration file API. It provides methods for reading key-value pairs from a file. The main benefit over using Java's standard Properties class is support for nested array configuration values. This implementation is inspired by, but somewhat more basic than libconfig, a very useful C/C++ Configuration File Library.
In this Java File Tutorial we will basics of File and Directory in Java, How to Create File and Directory in Java, Utility methods provided by File API and Common Exception or Error you will face during File and Directory Creation or access time. Creating File is different than creating Thread in java as you don't have to implement any interface for making a Class as File in Java.
String manipulation forms the basis of many algorithms and utilities such as text analysis, input validation, and file conversion. This tutorial explores some of the needed basics. Unless otherwise noted, the following classes are contained in the java.lang library.
Java Tutorial or Core Java Tutorial or Java Programming Tutorial is a widely used robust technology. Let's start learning of java from basic questions like what is java tutorial, core java, where it is used, what type of applications are created in java and why use java.
Primitive types are the most basic data types available within the Java language; these include boolean, byte, char, short, int, long, float and double. These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind. Because these data types are defined into the Java type system by default, they come with a number of operations predefined. You can not define a new operation for such primitive types. In the Java type system, there are three further categories of primitives:
Every one in java development face java.lang.OutOfMemoryError now and then, OutOfMemoryError in Java is one problem which is more due to system's limitation (memory) rather than due to programming mistakes in most cases though in certain cases you could have memory leak which causing OutOfMemoryError. I have found that even though java.lang.OutOfMemoryError is quite common basic knowledge of its cause and solution is largely unknown among junior developers. In this article we will explore what is java.lang.OutOfMemoryError; Why OutOfMemoryError comes in Java application, different type of OutOfMemoryError and How to fix OutOfMemoryError in Java. This article is purely meant to provide basic knowledge of java.lang.OutMemoryError and won't discuss profiling in detail.
we will see how to hide file in Java or make hidden file in Java. As we said File API in Java doesn’t provide any method to make a file hidden in Java but still you can apply some quick tricks to hide files from Java program. Like in Unix environment any file whose names begin with dot (.) is hidden so you can name your file starting with dot (.) and your File will be hidden in Linux or Unix Environment.
Here’s an example to show you how to read a XML file in Java via DOM XML parser. The DOM interface is the easiest XML parser to understand, and use. It parses an entire XML document and load it into memory, modeling it with Object for easy traversal or manipulation.
Java provides several classes in java.io package to work with text, stream data and file system. I have provided several examples on Java Files and IO recently, this post is an index of all those posts and will keep growing as and when I will add new java IO tutorials.
