In this area,
choose the code style scheme and change it as required.
Settings of a code style scheme are automatically applied every time IntelliJ IDEA generates,
refactors, or reformats your code.
The code styles are defined at the project level and at the global level.
At the Project level, settings are grouped under the Project scheme, which
is predefined and is marked in bold font. The Project style scheme applies to the current project only.
The default scheme cannot be changed! When any modifications are made, IntelliJ IDEA automatically creates a copy of the default scheme.
If you want to use a different project level scheme, choose the desired scheme and copy its settings to project.
At the Global level, settings are grouped under the predefined Default scheme,
and any other scheme created by the user. The global settings are used
when the user doesn't want to keep code style settings with the project and share them.
From this drop-down list, select the scheme to be used. The predefined schemes are shown in bold.
The custom schemes, ones created as copies of the predefined schemes, are in plain text.
This link appears in the upper-right corner of the dialog when the current style or scheme are modified.
Click this button to discard changes.

Use tab character
If this check box is selected, tab characters are used:
On pressing the Tab key
For code reformatting
When the check box is cleared, IntelliJ IDEA uses spaces instead of tabs.
If this check box is selected, IntelliJ IDEA inserts tabs for indentation and reformatting.
IntelliJ IDEA inserts tabs in the beginning of each line
until a symbol other than the tab is inserted. After that when you press the tab key,
IntelliJ IDEA will enter spaces.
If this check box 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 check box is available if the
Use Tab Character check box is selected.
In this text box, specify the number of spaces included in a tab.
In this text box, specify the number of spaces (or tabs if the
Use Tab Character
