使用 import acm.program for java？

Question

Is there any standard coding syntax in java?

I was using System.acm.println while one of the stanford videos imports acm.program and use println for the same output.

Answer 1

Yes Java is a statically typed language and has a very specific syntax. Importing a package allows you to reference methods and classes within it without having to call it by it's full path. For example, if you write import java.lang.Math; then when you want to call the method pow you can write Math.pow(param1, param2); instead of java.lang.Math.pow(param1, param2; . So, Stanford's class is importing the class acm.program to make it simpler and faster to code. This is standard coding practice.
