如何设置NetBeans实现按Enter时自动格式化{}（仿IntelliJ效果）

Hey there! I totally get wanting that smooth IntelliJ-style formatting for curly braces in NetBeans—used to drive me crazy too until I figured out the settings. Here’s exactly how to set it up:

• Open NetBeans and head to Tools > Options (on Mac, it’s NetBeans > Preferences). You can also use the keyboard shortcut Alt+T then O on Windows/Linux to jump straight there.
• Switch to the Editor tab, then click the Formatting subtab at the top.
• Use the Language dropdown to select the language you’re coding in (e.g., Java, since this is a common ask for that language).
• In the Category list on the left, scroll down and select Braces. This is where you’ll tweak the brace behavior.
• For every relevant code block type (like Block statement, Method declaration, If statement), adjust these two settings:
  • Set Opening brace to "New line" (some versions might label this "Next line").
  • Set Closing brace to "New line" as well.
• Next, hop over to the Indentation subtab (still under Editor > Formatting). Make sure the "Indent inside braces" option is checked—this ensures the line you type after pressing Enter gets auto-indented, just like IntelliJ does.
• Hit Apply then OK to save your changes.

Now give it a test: type {}, move your cursor between the two braces, press Enter. NetBeans should automatically format it to look like this:

{
    // Your code goes here
}

If you work with multiple languages, just repeat these steps for each language in the Language dropdown to get the same behavior across all your projects.
