i do not mean jNode only NodeJS or Node it is a server side programming framework based on javascript and google chromes v8 engine.
But i understand you. In most computer science studies you only learn a little bit Java. I was lucky to have a little bit c-basics as well.
If you only know Java use Java but you have to keep in mind maybe for the future:
If you need an api that only stores data in a database and read data from that database a java-Server with java backend is very complex.
You should choose a technology that fits your needs best.
