Aggregate operations, the Lambda Goodness in Java

One of the primary uses of Lambda expressions is to implement aggregate operations that can often be parallelized using multi-core processors we have today. The computation over bulk data structures is an area where Lambda expressions provide much needed support where part of the computation is caller defined. Doug Lea’s JSR166y Concurrency interest group exactly … Read moreAggregate operations, the Lambda Goodness in Java
