What are some common mistakes when using Java lambda expressions?
Some common mistakes include not using the correct functional interface, misunderstanding scope, and not handling exceptions properly.
Can you explain what a functional interface is?
A functional interface is an interface that has exactly one abstract method, which can be implemented using a lambda expression.
What about scope issues? Can you give an example?
Sure! A common scope issue is trying to modify a variable from the enclosing scope inside a lambda, which can lead to compilation errors.
How can I handle exceptions in lambda expressions?
You can handle exceptions by wrapping the lambda in a try-catch block or by using a custom functional interface that allows for checked exceptions.
