Essential IntelliJ IDEA Java Shortcuts for Developers
Written on
Chapter 1: Introduction
In my previous article discussing my top five IntelliJ plugins, I received an overwhelming response. Now, let's delve into another aspect of IntelliJ IDEA that has become essential for Java developers: the keyboard shortcuts that can significantly enhance your programming speed and efficiency.
Section 1.1: Generating the Main Method
One of the most recognized shortcuts is the ability to quickly generate the main() method. By using the psvm command, you can effortlessly create your main() method.
Section 1.2: Simplifying Print Statements
Instead of typing out System.out.println, the sout command allows you to print messages with ease.
Section 1.3: Assigning New Object Parameters
Less known but equally useful is the .var shortcut for swiftly assigning values to new objects.
Section 1.4: Creating For Loops
The .for shortcut enables you to quickly set up a for loop, streamlining your coding process.
Section 1.5: Conditional Statements Made Easy
For common boolean and string conditions, there are several shortcuts you can utilize:
- boolean.if → if(boolean)
- boolean.else → if(!boolean)
- string.null → if(string==null)
- string.nn → if(string!=null)
- string.switch → switch(string)
Section 1.6: Quick Try-Catch Blocks
The .try command simplifies the creation of try-catch blocks.
Section 1.7: Type Casting Made Simple
For type casting, the .castvar shortcut eliminates the need to manually type class names and values.
Section 1.8: Elevating Local Variables
Use the .field command to easily promote local variables to the global scope.
Section 1.9: Defining Optional Types
Quickly define Optional types using the .opt shortcut.
Section 1.10: Generating Lambda Expressions
Lastly, the .lambda shortcut allows for quick generation of lambda statements.
I hope you find these shortcuts beneficial in your coding journey. As a backend software engineer, I encourage those eager to learn more about technology to follow my channel for insights from my daily experiences.
