Switch Expressions
Switch Expressions is a new feature in Java 12 that allows developers to write more concise and readable code when dealing with switch statements. Prior to Java 12, switch statements were limited to using the break statement to exit each case block. This could lead to code that was difficult to read and maintain, especially for complex switch statements with many cases. With Switch Expressions, developers can now use the arrow (->) operator to return a value from a case block, making the code more concise and easier to read.

Why Learn Switch Expressions?
There are several benefits to learning Switch Expressions, including:
- Improved code readability: Switch Expressions make it easier to read and understand switch statements, especially for complex statements with many cases.
- Reduced code maintenance: Switch Expressions eliminate the need for break statements, which can reduce the amount of code that needs to be maintained.
- Increased code performance: Switch Expressions can improve the performance of switch statements, especially for large statements with many cases.
- Simplified code development: Switch Expressions make it easier to develop and maintain switch statements, which can save time and effort.
How Can Online Courses Help?
There are many online courses available that can help you learn Switch Expressions. These courses can provide you with the knowledge and skills you need to use Switch Expressions effectively in your own code. Some of the skills and knowledge you can gain from these courses include:
- How to use the arrow (->) operator to return a value from a case block
- How to use the default case to handle cases that don't match any of the other cases
- How to use the switch expression syntax to write more concise and readable code
Online courses can be a great way to learn Switch Expressions. They can provide you with the flexibility to learn at your own pace and on your own schedule, and they can give you access to expert instructors who can answer your questions and help you troubleshoot problems.
Are Online Courses Enough?
While online courses can be a helpful learning tool, they are not enough to fully understand Switch Expressions. To fully understand Switch Expressions, you need to practice using them in your own code. You can do this by creating your own projects or by contributing to open source projects.
Conclusion
Switch Expressions are a powerful new feature in Java 12 that can help you write more concise and readable code. If you are a Java developer, it is worth learning how to use Switch Expressions. Online courses are a great way to learn about Switch Expressions. However, it is important to remember that online courses are not enough to fully understand Switch Expressions. To fully understand Switch Expressions, you need to practice using them in your own code.
