Descrizione

Descrizione del profilo professionale

Il linguaggio di programmazione Java, progettato per essere il più possibile indipendente dalla piattaforma di esecuzione, venne creato per soddisfare cinque obiettivi primari: essere semplice, orientato agli oggetti e familiare; essere robusto e sicuro; essere indipendente dalla piattaforma; contenere strumenti e librerie per il networking; essere progettato per eseguire codice da sorgenti remote in modo sicuro.

Obiettivi

• Creare applicazioni multi-threaded ad alte prestazioni
• Creare applicazioni Java che sfruttano le caratteristiche object-oriented del linguaggio Java, come l’incapsulamento, l’ereditarietà e il polimorfismo
• Implementare funzionalità di input / output (I / O) per leggere e scrivere i dati e file di testo e capire flussi avanzati di I / O
• L’esecuzione di un’applicazione Java dalla riga di comando
• Manipolare file, directory e file system che utilizzino lo standard JDK NIO.2
• Creare applicazioni che utilizzano il framework Java Collections
• Eseguire varie operazioni su tabelle di database: creazione, lettura, aggiornamento e cancellazione utilizzando sia JDBC che JPA
• Ricercare e filtrare le collections con le Lambda Expressions
• Implementare tecniche di gestione degli errori attraverso la gestione delle eccezioni
• Utilizzare la concorrenzialità delle Lambda Expression
