Le novità di Java 8

Finalmente, dopo tanto tempo, una release di Java che merita di essere adottata in fretta, sia per le notevoli semplificazioni di alcune parti del codice, sia per i potenziali vantaggi in termini di efficienza delle nostre applicazioni. Le novità sono molte. Solo per citare le principali: le espressioni Lambda, la Streams API, un meccanismo generale per evitare le fatidiche NullPointerException, e ,finalmente, una nuova Date & Time API. Numerosi esempi ci convinceranno ad installare subito questo Java 8.

Xtend

Xtend è un linguaggio per JVM simile a java che a differenza di altri linguaggi simili compila in codice sorgente java standard promettendo un livello di integrazione con il mondo java superiore a quello di altri linguaggi come Scala o groovy. L’obiettivo è mantenere la compilazione statica, aggiungendo nel contempo numerose features tipiche dei linguaggi di ultima genereazione, sintactic sugar e la possibilità di partecipare alla procedura compilazione (macro).
