Perl was developed in 1987 by Larry Wall. Perl Supports object-oriented as well as procedural programming. It is a lot like C and C++. Perl was originally developed for text processing.
Java is one of the widely used programming language. Not only Java is a programming language but also a computing platform. Java was released by Sun Microsystems in 1995 which was initiated by James Gosling. According to Oracle java runs on 3 billion devices worldwide. It is intended to let developers to WRITE ONCE, RUN ANYWHERE, meaning a Java program can be compiled in one platform and executed in any other platform having JVM.
Below are some major differences between Perl and Java
|Introduction||“Perl is a general-purpose high-level language popular for CGI scripts. Some of the popular projects in Perl are CPanel and Bugzilla. It was initially designed to replace complex shell scripts.||Java is a programming language and a computing platform. Still there are softwares and websites that won’t work unless you have java installed. It is fast, secure and reliable.”|
|Compiled Format||Perl 6 is specifically compiled to Parrot Bytecode, while Perl 5 and older versions are interpreted language. It is stored with extension .pbc.||Java programs are compiled to bytecode.
Java bytecode can be shared through the network and then can be executed on any machine having JVM. It is stored with extension .class.
|Associative Arrays||Associative Arrays are defined very concisely for Perl.||Java does not have a concise way of creating associative arrays. However it hash implementations.|
|Focus||Common tasks such as file scanning and report generation are accentuately supported by Perl.||Java mostly focuses on application development, software tools, server app, and big data technologies.|
|File Extension||Perl programs are saved with .pl extension.
|Java programs are saved with .java extension.
|Typed Method||Perl is dynamically typed i.e. most of the type checking is performed during run time.||Java is statically typed i.e. most of its type checking is performed during compile time.|
|Comments and Documentation||
Inline comments in Perl are written using #
E.g. #Inline-Comment in Perl
Documentation in Perl is done using = and =cut.
Single line comments in Java are declared using //
Eg: //Single line Comment .
Multiline comments are written using /*……*/
Documentation in Java is done using.
|End of Statement||In Perl every statement must end with a semi-colon(;)||In Java every statement must end with a semi-colon(;)|
