  • From Python to Java
  • Why Python?
    • Less effort
    • Regular Expressions for manipulating text
    • Lot of pre-existing bioinformatics Python modules ( BioPython )
    • Python is widely used in the biology community, and it is a language well suited for writing Web applications
    • Good for quick prototypes
  • Why not Python (Ensembl)?
    • “ Some aspects of Python are not well suited for a software project of Ensembl's size”.
    • “ absence of compile time checking of function prototypes and variable types is a steady source of runtime errors .”
  • Why Java?
    • Java is platform independent and hence easily distributable.
    • Ideal for Visualization
    • Ensj , BioJava APIs
    • Since lot of standards and software engineering tools (IDEs,Testing, etc) are built for Java we can build applications that are robust and heavy duty
  • Why Java (Ensembl)
    • “compile time type checking ,
    • enforced interfaces ,
    • multi threading ,
    • better support for graphical user interfaces ,
    • and correct garbage collection of circularly referenced objects ”.

  • Hello World!
    • // Hello.java
    • public class Hello {
    • public static void main(String[] args) { System.out.println("Hello, world!");
    • }
    • }
  • Hello World!
    • import java.awt.*;
    • import java.awt.event.*;
    • import javax.swing.*;
    • public class HelloSwing extends JFrame
    • {
    • public static void main (String[] args){
    • JOptionPane.showMessageDialog(null, "Hello World");
    • }
    • }
  • Syntax isn’t important for me
    • But the JVM cares!
    • Casesensitivity
    • E.g System.out.println != system.out.println
  • Summary
    • Java is increasingly being adopted by Bioinformatics community
    • Many former Perl based applications and APIs are currently being rewritten in Java (e.g. BioMOBY, Ensembl etc.)
    • With release of advanced Java APIs and improved Java Virtual Machine some of the drawbacks were eliminated (e.g. Regular Expression, Casting)
  • References
