Today, we’ll learn more about Java by comparing it to what we already know about Python.
What’s going on behind the IDE?
- You can run Python in the interpreter…but not Java programs
- Java is compiled
- running Java programs from the command line
What we need for a Java program
- Every Java program must define a class, and all code is inside a class
- Everything in Java must have a type
- Every Java program must have a function called ‘public static void main(String args)’
