Grundkurs i Java
Java är det största applikationsutvecklingsspråket och har utvecklats på ett imponerande sätt under de två årtionden det har funnits. Denna kurs ger dig grunderna i språket och delar av det enorma standardbiblioteket, så att du snabbt kan komma igång efter kursen med programutveckling på server-sidan.
- Java JDK
- MS Visual Code || JetBrains IntelliJ IDEA
Du sitter bekvämt framför datorn och deltar i kursen via internet. Vi använder programvaran Zoom för alla våra fjärrkurser.
I priset ingår kursmaterial som PDF.

Om ni är tre eller fler personer från samma företags, kan ni beställa en företagsanpassad kurs. Då håller vi kursen på ett datum som passar er. Antingen på plats i era lokaler eller som en fjärrkurs. Vi kan även mixa fjärr- och klassrumskurs, om några av er önskar delta på distans medan resten föredrar att ses på plats.
