Examples of java.io.FileReader

java.io.FileReader
FileReader is class for turning a file into a character Stream. Data read from the source is converted into characters. The encoding is assumed to 8859_1. The FileReader contains a buffer of bytes read from the source and converts these into characters as needed. The buffer size is 8K. @see FileWriter
