Java vs. Perl
Every time that you run Perl, in rough terms, it compiles the source code into the bytecode and then starts executing the bytecode. Javac compiles programs into bytecode, then Java runs the bytecode in the Java virtual machine. For basic operations, Java is generally more verbose than Perl. In Perl, hashes are defined very concisely while in Java, there's no standard way to define hashes.
Key Differences
All Perl modules are organized via the CPAN, which is mirrored around the globe. All uploads into the CPAN are automatically tested across a wide range of architectures and operating systems via the CPAN testers group. Java does not have asingle recognized repository for reusable code, but instead has multiple sources for standardized Java extensions.
Perl supports multiline strings, by simply inserting line breaks in the string, or by using theHERE-DOC syntax. Perl also supports scalar, array and hash element interpolation in strings delimited by double quotes. Java supports multiline strings by using the "n" escape code to indicate a line break and the + operator to break a long string constant into pieces on successive lines. Variable interpolation is performed by the String. Format () method.

Perl documentation is usually installed with the interpreter and available by using the perldoc command, a web mirror of the documentation for all perl releases since 5.8.8 is available at http://perldoc.perl.org/. All standard Java is documented using javadoc, a tool for dynamically creating html documentation of java API's using code comments.
Perl uses a simple naming and versioning scheme: Perl 4, 5_005, 5.6, 5.8, 5.10, 5.12, 5.14, 5.16, 5.18. Java 1.5.0 became Java 5, Java 1.6.0 became 6. Java 6 dropped thej2se name and is now just javase.

Java
An object-oriented computer programming language, derived largely from C++, used widely for design and display of web pages on the world-wide web. It is an interpreted language, and has been suggested as a platform-independent code to allow execution of the same progam under multiple operating systems without recompiling. The language is still (1997) under active development, and is evolving.

What is Java?
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
What is Perl?
Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages. The languages in this family include Perl 5 and Perl 6. Perl supports multiline strings, by simply inserting line breaks in the string, or by using the HERE-DOC syntax. Perl also supports scalar, array and hash element interpolation in strings delimited by double quotes.
