Perl vs Java

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’.
