When a class has multiple constructors, or multiple methods with the same name, these appear sequentially, with no other code in between not even private members. Terminology Note: block-like construct refers to the body of a class, method or constructor. Note that, by Section 4. Braces are used with if , else , for , do and while statements, even when the body is empty or contains only a single statement.
Braces follow the Kernighan and Ritchie style " Egyptian brackets " for nonempty blocks and block-like constructs:. A few exceptions for enum classes are given in Section 4. Each time a new block or block-like construct is opened, the indent increases by two spaces. When the block ends, the indent returns to the previous indent level. The indent level applies to both code and comments throughout the block. See the example in Section 4. Java code has a column limit of characters. A "character" means any Unicode code point. Except as noted below, any line that would exceed this limit must be line-wrapped, as explained in Section 4.
Each Unicode code point counts as one character, even if its display width is greater or less. For example, if using fullwidth characters , you may choose to wrap the line earlier than where this rule strictly requires. Terminology Note: When code that might otherwise legally occupy a single line is divided into multiple lines, this activity is called line-wrapping.
There is no comprehensive, deterministic formula showing exactly how to line-wrap in every situation.
Very often there are several valid ways to line-wrap the same piece of code. Note: While the typical reason for line-wrapping is to avoid overflowing the column limit, even code that would in fact fit within the column limit may be line-wrapped at the author's discretion. Tip: Extracting a method or local variable may solve the problem without the need to line-wrap. The prime directive of line-wrapping is: prefer to break at a higher syntactic level.
Note: The primary goal for line wrapping is to have clear code, not necessarily code that fits in the smallest number of lines. In general, two continuation lines use the same indentation level if and only if they begin with syntactically parallel elements. Section 4. A single blank line may also appear anywhere it improves readability, for example between statements to organize the code into logical subsections.
A blank line before the first member or initializer, or after the last member or initializer of the class, is neither encouraged nor discouraged. Beyond where required by the language or other style rules, and apart from literals, comments and Javadoc, a single ASCII space also appears in the following places only. This rule is never interpreted as requiring or forbidding additional space at the start or end of a line; it addresses only interior space. Terminology Note: Horizontal alignment is the practice of adding a variable number of additional spaces in your code with the goal of making certain tokens appear directly below certain other tokens on previous lines.
This practice is permitted, but is never required by Google Style. It is not even required to maintain horizontal alignment in places where it was already used. Tip: Alignment can aid readability, but it creates problems for future maintenance. Consider a future change that needs to touch just one line. This change may leave the formerly-pleasing formatting mangled, and that is allowed. More often it prompts the coder perhaps you to adjust whitespace on nearby lines as well, possibly triggering a cascading series of reformattings.
That one-line change now has a "blast radius. Optional grouping parentheses are omitted only when author and reviewer agree that there is no reasonable chance the code will be misinterpreted without them, nor would they have made the code easier to read. It is not reasonable to assume that every reader has the entire Java operator precedence table memorized.
After each comma that follows an enum constant, a line break is optional. Additional blank lines usually just one are also allowed. This is one possibility:. An enum class with no methods and no documentation on its constants may optionally be formatted as if it were an array initializer see Section 4.
Every variable declaration field or local declares only one variable: declarations such as int a, b; are not used. Exception: Multiple variable declarations are acceptable in the header of a for loop. Local variables are not habitually declared at the start of their containing block or block-like construct. Instead, local variables are declared close to the point they are first used within reason , to minimize their scope.
Local variable declarations typically have initializers, or are initialized immediately after declaration. Any array initializer may optionally be formatted as if it were a "block-like construct. The square brackets form a part of the type , not the variable: String args , not String args. Terminology Note: Inside the braces of a switch block are one or more statement groups. Each statement group consists of one or more switch labels either case FOO: or default: , followed by one or more statements or, for the last statement group, zero or more statements.
The following switch label returns to the previous indentation level, as if a block had been closed. Within a switch block, each statement group either terminates abruptly with a break , continue , return or thrown exception , or is marked with a comment to indicate that execution will or might continue into the next statement group. This special comment is not required in the last statement group of the switch block. Notice that no comment is needed after case 1: , only at the end of the statement group.
Each switch statement includes a default statement group, even if it contains no code. Exception: A switch statement for an enum type may omit the default statement group, if it includes explicit cases covering all possible values of that type. This enables IDEs or other static analysis tools to issue a warning if any cases were missed. Annotations applying to a class, method or constructor appear immediately after the documentation block, and each annotation is listed on a line of its own that is, one annotation per line.
These line breaks do not constitute line-wrapping Section 4. Exception: A single parameterless annotation may instead appear together with the first line of the signature, for example:.
Annotations applying to a field also appear immediately after the documentation block, but in this case, multiple annotations possibly parameterized may be listed on the same line; for example:. This section addresses implementation comments. Javadoc is addressed separately in Section 7, Javadoc. Any line break may be preceded by arbitrary whitespace followed by an implementation comment. Such a comment renders the line non-blank. Block comments are indented at the same level as the surrounding code.
Class and member modifiers, when present, appear in the order recommended by the Java Language Specification:. For example, L rather than l. Identifiers use only ASCII letters and digits, and, in a small number of cases noted below, underscores. In Google Style, special prefixes or suffixes are not used.
