Regardless of whether or not we are using lambda expressions, we use the Java interface shown in Listing 3 in place of the C++ typedef to specify the signature of the function parameter.

As we’ll see, functional interfaces combined with anonymous inner classes are often used with lambda expressions. Like C# lambda expressions, Java 8 lambda expressions tie an argument list to a ...

So a more concise lambda expression that implements this Java Function interface would look like this: When the code implements Java Function with a concise lambda expression runs, the program prints ...

The goal of a lambda expression is to reduce the verbosity of Java code, especially for those situations where you need to override an interface with only one functional method. Here is how the code ...

But adding Lambda expressions to Java 8 had a side effect: it made the Collections API look especially long in the tooth. It forced the Oracle team to "bite the bullet," Goetz said, and addressed the ...
