Our series of posts about solving the OutOfMemoryError in our hypothetical production system is coming to a conclusion. We have covered a number of different ways to attack OutOfMemoryErrors so far - profilers, JDK bundled tools and heap dump analyzers. Our today’s mercenaries will be Application Performance Management tools, or APMs

I have found a way of preventing deadlocks in java. The methodology(which is code) completely prevents the deadlock from occuring by detecting it in advance. This can be used across the systems seamlessly.
Kindly let me know what I need to do next. I want this to be part of next jdk release. I am writing this email as I have no idea what I need to do next to bring it into limelight.
Thanks & Regards,
how do you write a java program that picks three numbers from the keyboard and computes their mean and product
Creational Design Patterns
Java software developers use agile methodologies to create rich applications for the client. Applications of wide array of Java applications are designed using cloud methodologies. Technocrats are developing more sophisticated and stand alone software for the web as well as one touch solution for the smartphone. Java product development firm are delivering enterprise customized solution using evaluated codes and process modules. Scalable out of box well architected enterprise solution are easily developed on J2EE (Java 2 Platform Enterprise Edition) platform. Java experts are well versed with J2EE methodologies, using this programming language to design a custom based end to end solution and run test suits to reduced complexity and easily accessible. Java software developers understand that client’s business visibility in an integral part on the web, focusing on deliver web application that allows client to provide their capable services to its customer is the basic motto of offshore software firms.
Web and mobile application capable to run on any operating system with security enhanced features which improve the performance are some of the hybrid advantages enterprises who’ve leveraged a solution from Java product development firm. Fast debugging and deployment practices executed by the Java experts on the enterprise leveraged custom solution with agile methodologies does provide a unique platform to the offshore firm offering java software developers service. Modern technology has brought a big revolution in the frameworks of developing Java server side based application. Java experts use software like Java Virtual Machine (JVM) to build robust server side application which are decrease the workload on various servers therefore helping enterprises to gain profit by delivering quality performance.
Memory leakage, adjusting critical performance, handicapped local domain knowledge, load malfunctions, glitches and errors where the evident problem of the past, Java product development have incorporated dynamic features like enhanced security measures, load balancing, embedded platforms, control panel administration, testing services and much more.
Java programming language was first introduced by James Gosling in early 90s and this introduction changed the entire application development industry. Unlike its competitor like C and C++, java application is portable and inherits all the features for modern Object oriented Programming languages. Enterprises leverage a web application using Java based technology for its robust and dynamic features that benefits the business of the client to attract more customers. Java Applications are highly secure and come with inbuilt methods like garbage collection and efficient exception handling. Today java application are being user everywhere be it computing platforms, Mobile applications, Enterprise wide applications ranging from highly complex application to desktop applications. Java applications are platform independent and can run on any machine with Java Virtual Environment or JVM. JVM runs the byte code.
Java Web applications are highly robust and high performing when it comes to development of web based applications. The companies that provide contract java developers provide specialties in Java application and Java Web Application Development services and Solutions. These services may include Java Web Application Development, J2EE Web Application Development, Spring Java Web Development, Struts J2EE Web Development, Custom Java Web and Application Development etc. These contract java developers are provided by outsourcing companies at competitive price, thus helping companies in leveraging Java Application and Java Web application expertise to achieve their business objectives.
Offshore Contract java developers provider companies have highly skilled pool of resources which specialize in Java technology for all type of environments, be it standalone or web based. These contract java developers are architect level programmers and have domain experience like of banking and finance, healthcare, insurance, airlines etc. This domain expertise helps them easily understand client business functions and they accordingly develop java application for the same.

The complete segregation of a script's variables from those in the lexical scope of the embedding Java program greatly hinders the use of scripting languages in large-scale applications. This article describes the use and development of "InScript" -- a tool that enables embedded scripts in any JSR-223 language to read and write Java variables naturally, without requiring manually programmed "put()"s and "get()"s to move values to and from the script engine. The freedom to use Java variables in scripts makes it easy to customize programs, or even implement large portions of programs, with scripts.
The term "first-class function" is now very well-known, partly because of the renewed interest in functional-programming languages (Scala, Clojure, Erlang, etc.). But a quick google search shows that the only well-known meaning of "first-class code" is a category of airline travel that includes "Supersonic or First Class Suite (currently only on the Airbus A380)"! Well, for the purposes of this article, script embedded in a Java program is not "first-class code" because it can not use in-scope Java variables unless the variables have been put into the script engine by explicit program action.
This article describes the use and development of "InScript" -- a tool that enables scripts in any JSR-223 supported language to use in-scope variables from the embedding Java program naturally -- without the need for any manually programmed action on the Java variables.
