Eclipse Essential Tips: List of Code Formatting Shortcut Keys

Eclipse is a very popular IDE (Integrated Development Environment) that is widely used for Java development. In the process of writing code, code formatting is very important, it can improve the readability of the code and reduce errors. Eclipse provides many shortcut keys to help us quickly format code. Next, we will introduce some commonly used code formatting shortcut keys and provide specific code examples.

1. Ctrl Shift F: This is the most commonly used code formatting shortcut key in Eclipse. It can format selected code blocks according to unified format specifications. The following is an example:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

After using the Ctrl Shift F shortcut key, the code will be formatted in the following form:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

2. Ctrl I: This shortcut key is used Select single or multiple lines of code for quick indentation. The following is an example:

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}

After using the Ctrl I shortcut key, the code will be formatted in the following form:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

3. Ctrl Shift O: This shortcut key is used Automatically import missing packages. The following is an example:

public class HelloWorld {
    public static void main(String[] args) {
        Date currentDate = new Date();
        System.out.println(currentDate.toString());
    }
}

After using the Ctrl Shift O shortcut key, Eclipse will automatically import the missing package, and the code will become the following form:

import java.util.Date;

public class HelloWorld {
    public static void main(String[] args) {
        Date currentDate = new Date();
        System.out.println(currentDate.toString());
    }
}

4. Ctrl / and Ctrl Shift /: These two shortcut keys are used to insert and cancel single-line comments and multi-line comments. We can use these two shortcut keys in the code to quickly add and delete comments. The following is an example:

public class HelloWorld {
    public static void main(String[] args) {
        // System.out.println("Hello, World!");
        System.out.println("Hello, Eclipse!");
    }
}

After using the Ctrl/shortcut key, the code will become the following form:

public class HelloWorld {
    public static void main(String[] args) {
        // System.out.println("Hello, World!");
        // System.out.println("Hello, Eclipse!");
    }
}

After using the Ctrl Shift/shortcut key, the code will become The following form:

public class HelloWorld {
    public static void main(String[] args) {
        /*
         * System.out.println("Hello, World!");
         * System.out.println("Hello, Eclipse!");
         */
    }
}

The above are some commonly used code formatting shortcut keys and specific code examples. Proficient in these shortcut keys will greatly improve the efficiency of our code writing and make our code more standardized and readable. By constantly applying these techniques, we can better develop using Eclipse. Hope this article helps you!
