Code-cleanup
Avoid Commented-out lines of code
Generic exceptions Error, RuntimeException, Throwable and Exception should never be thrown : Define and throw a dedicated exception instead of using a generic one.
Nested blocks of code should not be left empty : Either remove or fill this block of code.
if/else/for/while/do statements should always use curly braces : Missing curly brace.
Declarations should use Java collection interfaces such as "List" rather than specific implementation classes such as "LinkedList" :
Modifiers should be declared in the correct order : Reorder the modifiers to comply with the Java Language Specification.
Exception handlers should preserve the original exception : Either log or rethrow this exception.
Collection.isEmpty() should be used to test for emptiness : Use isEmpty() to check whether the collection is empty or not.
A public method should have at least one checked exception
