Perl vs Java

JavaServer Side ProgrammingProgramming

Java

  • Java is an object oriented programming language as well as a computing platform.
  • It is safe, quick and reliable.
  • The code in Java is first converted into bytecode and then executed using a JVM (Java Virtual Machine).
  • The java program that is converted into bytecode is stored with the help of the extension ‘.class’.
  • Java doesn’t give any specific way in which associative arrays could be stored, instead there are implementations of various hash functions.
  • Java programs that need to be run are stored with the extension ‘.java’.
  • Java is a statically typed language, i.e type checking is performed during compile-time (not run-time).
  • Single line comments in Java are specified using ‘//’.
  • Multi-line comments in Java are specified using ‘/*’ and ends with ‘*/’.
  • Java documentation is done with the help of ‘/**’ and ends with ‘*/’.
  • Every statement ends with a ‘;’.

Perl

  • Every statement ends with a ‘;’.
  • It is considered as a general purpose high-level language.
  • It was created to replace with shell scripts that were too complex.
  • Versions before and up to Perl 5 is considered to be interpreted language.
  • Perl 6 version is compiled to Parrot Bytecode and stored with the extension ‘.pbc’.
  • Associative arrays are specifically defined in Perl.
  • Perl code is stored with the extension ‘pl’.
  • It is a dynamically typed language, i.e. the type of variables and functions is checked at runtime.
  • Comments are written in Perl code using ‘#’.
  • Documentation is specified in Perl code using ‘=’ and ‘=cut’.
