Företagsintern Kurs

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 t.ex. programutveckling på server-sidan.
