Checks that there are no import statements that use the * notation.

Rationale: Importing all classes from a package or staticmembers from a class leads to tight coupling between packagesor classes and might lead to problems when a new version of alibrary introduces name clashes.

Checks for long lines.

Rationale: Long lines are hard to read in printouts or if developershave limited screen space for the source code, e.g. if the IDEdisplays additional information like project tree, class hierarchy,etc.

Validates abbreviations (consecutive capital letters) length in identifier name,it also allows to enforce camel case naming. Please read more atGoogle Style Guideto get to know how to avoid long abbreviations in names.

allowedAbbreviationLength specifies how many consecutive capital letters areallowed in the identifier.A value of 3 indicates that up to 4 consecutive capital letters are allowed,one after the other, before a violation is printed. The identifier 'MyTEST' would beallowed, but 'MyTESTS' would not be.A value of 0 indicates that only 1 consecutive capital letter is allowed. Thisis what should be used to enforce strict camel casing. The identifier 'MyTest' wouldbe allowed, but 'MyTEst' would not be.

ignoreFinal, ignoreStatic, and ignoreStaticFinalcontrol whether variables with the respective modifiers are to be ignored.Note that a variable that is both static and final will always be considered underignoreStaticFinal only, regardless of the values of ignoreFinaland ignoreStatic. So for example if ignoreStatic is true butignoreStaticFinal is false, then static final variables will not be ignored.

Checks the style of array type definitions. Some like Java style:public static void main(String[] args) and some likeC style: public static void main(String args[]).

By default the Check enforces Java style.

This check strictly enforces only Java style for method return typesregardless of the value for 'javaStyle'. For example, byte[] getData().This is because C doesn't compile methods with array declarations on the name.

Checks that the groups of import declarations appear in the order specifiedby the user. If there is an import but its group is not specified in theconfiguration such an import should be placed at the end of the import list.

Sometimes two consecutive 'if' statements can be consolidated by separating their conditions with a boolean short-circuit operator.

Example:

void bar() {
 if (x) { // original implementation
 if (y) {
 // do stuff
 }
 }
}

void bar() {
 if (x && y) { // optimized implementation
 // do stuff
 }
}
