In Java 7 or higher, you can also use Files.readAllBytes() to read a file into an array of bytes. Later, you can convert the byte array into a string as shown below: try { // read all bytes byte[] bytes = Files.readAllBytes(Paths.get("input.txt")); // convert bytes to strin...
There was no easy way to read a text file as String in Java untilJDK 7, which released NIO 2. This API now provides a couple of utility methods that you can use to read the entire file as String e.g.Files.readAllBytes()returns a byte array of the entire text file. You can conver...

Bytes are read starting at this channel's current file position, and then the file position is updated with the number of bytes actually read. Otherwise this method behaves exactly as specified in the ReadableByteChannel interface. Java documentation for java.nio.channels.FileChannel.read(java.nio...
