+# File Handling
+ **There are two type of class hierarchies for file handling**
+* [Byte Stream Classes:](#byte-stream-class)
+    They are used to perform Input and Output of 8-bit bytes. There are many abstract classes available for handling byte stream. Most widely used are `FileInputStream` and `File Output Stream` 
+* Character Stream Classes: 
+    They are used to perform Input and Output for 16-bit Unicode. There are different classes to handle Character Stream Classes as well. Most widely used are `File Reader` and `File Writer`
+
+## Byte Stream Class 
+**Example**
+```java
+import java.io.*;
+public class CopyFile {
+
+   public static void main(String args[]) throws IOException {  
+      FileInputStream in = null;
+      FileOutputStream out = null;
+
+      try {
+         in = new FileInputStream("input.txt");
+         out = new FileOutputStream("output.txt");
+         
+         int c;
+         while ((c = in.read()) != -1) {
+            out.write(c);
+         }
+      }finally {
+         if (in != null) {
+            in.close();
+         }
+         if (out != null) {
+            out.close();
+         }
+      }
+   }
+}
+```
