Sanity4J was created to simplify running multiple static code
analysis tools on the Java projects. It provides a single entry
point to run all the selected tools and produce a consolidated
report, which presents all findings in an easily accessible
manner.

LocalVariableCouldBeFinal:
A local variable assigned only once can be declared final.
MethodArgumentCouldBeFinal:
A method argument that is never assigned can be declared final.
AvoidInstantiatingObjectsInLoops:
Detects when a new object is created inside a loop
UseArrayListInsteadOfVector:
ArrayList is a much better Collection implementation than Vector.
SimplifyStartsWith:
Since it passes in a literal of length 1, this call to String.startsWith can be rewritten using String.charAt(0) to save some time.
UseStringBufferForStringAppends:
Finds usages of += for appending strings.
UseArraysAsList:
The class java.util.Arrays has a "asList" method that
should be use when you want to create a new List from
an array of objects. It is faster than executing a loop to
cpy all the elements of the array one by one
AvoidArrayLoops:
Instead of copying data between two arrays, use
System.arraycopy method
UnnecessaryWrapperObjectCreation:
Parsing method should be called directy instead.
AddEmptyString:
Finds empty string literals which are being added. This is an inefficient way
to convert any type to a String.
