Tabs and Indents

Item	Description
Use tab character	If this checkbox is selected, tab characters are used: On pressing the `Tab` key For indentation For code reformatting When the checkbox is cleared, IntelliJ IDEA uses spaces instead of tabs.
Smart tabs	If this checkbox is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of spaces. If this checkbox is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment. The Smart Tabs checkbox is available if the Use Tab Character checkbox is selected.
Tab size	In this text box, specify the number of spaces included in a tab.
Indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted for each indent level.
Continuation indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted between the elements of an array, in expressions, method declarations and method calls.

Spaces

Use this tab to specify where you want spaces in your code. To have IntelliJ IDEA automatically insert a space at a location, select the checkbox next to this location in the list. The results are displayed in the Preview pane.

Wrapping and braces

In this tab, customize the code style options, which IntelliJ IDEA will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.) The right-hand pane shows preview.

Alignment takes precedence over indentation options.

Keep when reformatting

Use the checkboxes to configure exceptions that IntelliJ IDEA will make when reformatting the source code. For example, by default, the Line breaks checkbox is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks check box before you reformat the source code.

Wrapping options

The wrapping style applies to the various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).

Item	Description
Wrapping style	From this drop-down list, select the desired wrapping style: Do not wrap - when this option is selected, no special wrapping style is applied. With this option selected, the nested alignment and braces settings are ignored. Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation. Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation. Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.

Alignment options

Item	Description
Align when multiline	If this checkbox is selected, a code construct starts at the same column on each next line. Otherwise, the position of a code construct is determined by the current indentation level.
`<character(s)>` on next line	Select this checkbox to have the specified character or characters moved to the next line when the lines are wrapped.
'else' on new line	Use this checkbox to have the corresponding statements or characters moved to the next line.
New line after `<character>`	Select this checkbox to have the code after the specified character moved to a new line.
Special else if treatment	If this checkbox is selected, `else if` statements are located in the same line. Otherwise, `else if` statements are moved to the next line to the corresponding indent level.
Indent case branches	If this checkbox is selected, the `case` statement is located at the corresponding indent level. Otherwise, `case` statement is placed at the same indent level with `switch`.

Braces placement options

Item	Description
Braces placement style	Use this drop-down list to specify the position of the opening brace in class declarations, method declarations, and other types of declarations. The available options are: End of line - select this option to have the opening brace placed at the declaration line end. Next line if wrapped - select this option to have the opening brace placed at the beginning of the line after the multiline declaration line. Next line - select this option to have the opening brace placed at the beginning of the line after the declaration line. Next line shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level. Next line each shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level, and have the next line shifted to the next indent level as well.
Force braces	From this drop-down list, choose the braces introduction method for `if`, `for`, `while`, and `do () while` statements. The available options are:
