Java is tegenwoordig de meest gebruikte ontwikkeltaal ter wereld. Hiermee kunnen programmeurs objecten maken die kunnen interageren met andere objecten om een ​​probleem op te lossen. Verken de basisprincipes van Java SE, inclusief de Java-technologie en het werken met objecten. Onderzoek de Java-taal, hoe u variabelen declareert, initialiseert en gebruikt, en hoe u operators en beslissingsconstructies gebruikt. Het maken en gebruiken van arrays en lusconstructies, het werken met methoden en overbelasting van methoden, het gebruik van encapsulatie en constructors, geavanceerde objectgeoriënteerde concepten, het afhandelen van fouten en het implementeren van applicaties komen ook aan bod.
