Welcome to Java for Python Programmers. This short ebook is an ongoing project to help Computer Science students who have had one or two semesters of Python learn the Java programming language. If you are not a part of that audience you may still find this a useful way to learn about Java. This book is written using the build on what you know philo...
Python is a nice language for beginning programming for several reasons. The syntax is sparse and clear. The underlying model is very simple. Everything is an object. You can write powerful and interesting programs without a lot of work. Python is representative of one kind of language, called a dynamic language. Dynamic languages can be interprete...
A time honored tradition in Computer Science is to write a program called “hello world.” The “hello world” program is simple and easy. There are no logic errors to make, so getting it to run relies only on understanding the syntax. To be clear lets look a a “complicated” version of hello world for Python: def main(): print "Hello World!" Remember t...
Now that we have run our hello world program, lets go back and look at it carefully to see what we can learn about the Java language. public class Hello { public static void main(String[] args) { System.out.println("Hello World!"); } } This simple example illustrates a few very important rules: Every Java program must define a class, all code is in...
One of the great things about Python is that all of the basic data types are objects. Integers are objects, floating point numbers are objects, lists are objects, everything. In Java that is not the case. In Java some of the most basic data types like integers and floating point numbers are not objects. The benefit of having these primitive data ty...
Java allows for conversions between the base types and between strings and base types. Unlike python, these con-versions must often be written explicitly. Some of these conversions may result in a loss of information if the source number is too large or has too great a precision to be stored in the target. The following table shows the syntax for s...
In Java you can use any class that is available without having to import the class subject to two very important conditions: The javac and java must know that the class exists. You must use the full name of the class You first question might be how do the java and javac commands know that certain classes exist. The answer is the following: Java kno...
Here is where we run into one of the most important differences between Java and Python. Python is a dynamically typed language. In a dynamically typed language a variable can refer to any kind of object at any time. When the variable is used, the interpreter figures out what kind of object it is. Java is a statically typed language. In a staticall...
In the previous section you saw that we created a Scanner object. In Java Scanner objects make getting input from the user, a file, or even over the network relatively easy. In our case we simply want to ask the user to type in a number at the command line, so in line 9 we construct a Scanner by calling the constructor and passing it the System.in ...
As I said at the outset of this Section we are going to use Java ArrayLists because they are easier to use and more closely match the way that Python lists behave. However, if you look at Java code on the internet or even in your Core Java books you are going to see examples of something called arrays. In fact you have already seen one example of a...
