How are Lambda expressions compiled in Java?
- Lambdas are compiled into native machine code for better performance.
- Lambdas are compiled into traditional anonymous inner classes.
- Lambdas are not compiled; they are interpreted at runtime.
- Lambdas are pre-compiled and stored as bytecode in a separate file.
In Java, Lambda expressions are compiled into traditional anonymous inner classes by the Java compiler. These inner classes capture the behavior defined by the Lambda expression. The use of inner classes allows the Java Virtual Machine (JVM) to treat Lambdas as objects with associated methods, which makes them compatible with existing Java features and enables the use of functional interfaces. Understanding this compilation process is crucial for developers who want to understand the inner workings of Lambdas and their impact on the bytecode.
