Back to the top: what to YOU MEAN by saying Start Java? Technically, there is nothing to start. Your RUN the Java compiler or Applet and/or you enable the browser to use an applet. The JRE (Java Runtime Environment) must be configured and the Class Path defined in all cases.

Optifine??? who / what is that?

First, Install Java
then get a command prompt and enter java -version
you should get something like

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) Client VM (build 25.131-b11, mixed mode, sharing)​

If so, Java is installed correctly, if not, you've made a mistake

Now verify that your browser can access Java:
Launch IE (Chrome & Firefox do NOT support Java)
