FileReader


The FileReader class makes it possible to read the contents of a file as a stream of characters. It works much like the FileInputStream except the FileInputStream reads bytes, whereas the FileReader reads characters. The FileReader is intended to read text, in other words

Syntax:
Reader reader = new FileReader("c:\\data\\input-text.txt");


Example:

Reader reader = new FileReader("c:\\data\\input-text.txt");

int data = reader.read();
while(data != -1) {
  //do something with data...
  doSomethingWithData(data);

  data = reader.read();
}
reader.close();
