Rule Definition
There is no dispute that these comments contribute to a developer's understanding and help a developer write reliable applications more quickly. Without documenting exception thrown it is dififcult for anyone else than the author to guess its purpose and consequences except by looking at the code that is throwing it.

Remediation
Add a @throws or @exception tag with a description for each method.

Violation Code Sample

public void f() throws IOException {     // body }

Fixed Code Sample

#Remediation Sample with @throws tag:  /**  * @throws IOException  If an input or output   *                      exception occurred  */ public void f() throws IOException {     // body }  #Remediation Sample with @exception tag:  /** * @exception StringIndexOutOfRangeException * if the index is not in the range <code>0</code> *  to <code>length()-1</code>.       */ public char charAt(int index) {        ...     }
