دانلود Pluralsight From Collections to Streams in Java 8 Using Lambda Expressions
جاوا 8 الگوها و بسترهای جدیدی برای ساختن برنامههای بسیار کارآمد و قدرتمند در اختیار کاربران قرار می‌دهد. این دوره‌ی آموزشی تصویری مفاهیم و تکنیک‌های بسیار مهمی را در زمینه‌ی عبارات لامبدا (Lambda Expressions) پوشش داده است. لامبدا گرچه بستر نرم‌افزاری بسیار خوبی است اما بدون فناوری‌های جدیدی که در جاوا ارائه شدند مفید و کارآمد نخواهد بود. در این آموزش، بهره‌گیری از فریم‌ورک‌های Collections و Streams در پلتفرم عالی جاوا 8 با استفاده از عبارات لامبدا مورد تدریس قرار گرفته‌اند.
محتوای آموزش:
1- آشنایی با عبارات لامبدا و Functional Interfaces
2- فرایند Writing Data Processing Functions با لامبدا در جاوا 8
3- پردازش اطلاعات با استفاده از لامبدا ها و چارچوب Collections
