Use shortcut keys in Eclipse to easily complete code formatting

Eclipse is a very popular Java Integrated Development Environment (IDE). It provides many functions and shortcut keys to facilitate developers to improve efficiency. One of the commonly used functions is code formatting. This article will introduce the formatting shortcut key in Eclipse and how to use it.

In Eclipse, code formatting is a very important operation. By formatting your code, you can make it clearly structured and easy to read and understand. In team development, a unified code style is also very important. Code consistency can be ensured through formatting.

In Eclipse, the shortcut key for formatting is Ctrl Shift F. By pressing this key combination, you can format the currently edited code or the selected code.

The formatting operation will make a series of adjustments to the code, including indentation, spaces, line breaks, alignment, etc. These adjustments will be made based on Eclipse's default settings or configured custom rules.

Eclipse's default formatting settings basically meet the needs of most developers. But for some special projects or personal habits, we can also make some customizations. The following describes how to perform customized formatting settings.

First, open Eclipse’s preferences. It can be opened through "Window" -> "Preferences" in the menu bar or the shortcut key Ctrl Shift L. In the pop-up dialog box, select "Java" -> "Code Style" -> "Formatter".

In the Formatter page, we can see the default code formatting style, including indentation and newline rules for various code elements (classes, methods, variables, etc.). We can select these styles to modify, or click the "New" button to create a new style.

When formatting code, you can format it according to the rules of code style. You can also customize formatting rules based on personal preferences or project requirements.

In addition to code formatting shortcut keys, Eclipse also provides other formatting functions.

If you want to format a selected piece of code, you can first select the code to be formatted, and then use the shortcut key Ctrl Shift F to format.

If you want to automatically format the code when writing code, you can set the save action of Eclipse. Select "Java" -> "Editor" -> "Save Actions" in the preferences. Check "Perform the selected actions on save" and then check "Format source code".

After the setting is completed, Eclipse will automatically format the code when saving the code to ensure that the format of the code complies with the specification.

To summarize, formatting code in Eclipse is a very practical function. By using the formatting shortcut Ctrl Shift F, we can easily format the code. If you need to customize code formatting rules, you can set them in the preferences. In addition, you can also set a save action to automatically format the code when saving the code. Using these functions can improve development efficiency, make the code more unified, beautiful, and easy to maintain.
