Switch Expressions
Save
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.
