Coding Rules

Name	Checked	Synopsis
StringandStringBuffer1		Don't use duplicate String literals; use constants instead
StringandStringBuffer2		Avoid instantiating String objects; this is usually unnecessary
StringandStringBuffer3		Avoid calling toString() on String objects; this is unnecessary
StringandStringBuffer4		Avoid concatenating nonliterals in a StringBuffer constructor or append()
StringandStringBuffer5		Using equalsIgnoreCase() is cleaner than using toUpperCase/toLowerCase().equals()
StringandStringBuffer6		This is an inefficient use of StringBuffer.toString; call StringBuffer.length instead
StringandStringBuffer7		Avoid appending characters as strings in StringBuffer.append
StringandStringBuffer8		Combine StringBuffer.append calls, if possible
StringandStringBuffer9		String.indexOf(char) is faster than String.indexOf(String)
StringandStringBuffer10		String.trim().length()==0 is an inefficient way to validate an empty String
StringandStringBuffer11		Initialize objects of StringBuffer with a proper size
StringandStringBuffer12		No need to call String.valueOf to append to a string
StringandStringBuffer13		Do not instantiate a StringBuffer with a char
StringandStringBuffer14		Use equals() to compare String objects
