Typically, it performs some operation on its argument object. Table 13.6 shows all the consumer … Read moreConsumers – Functional-Style Programming

The compiler determines the target type that is required in the context where the lambda … Read moreType Checking and Execution of Lambda Expressions – Functional-Style Programming
