For example, we have a file in our raw folder app/src/main/res/raw/sample_teas.json. To get anInputStream for reading it, from out Context context, we can do this:

• InputStream input = context.openRawResource(R.raw.sample_teas);

• InputStream input = context.getResources().openRawResource(R.raw.sample_teas);

• evaluate an expression at the current execution point
  
• advance to the next line in the code (without entering a method)
