A way to improve the Java code we write is to work with the best tools. So, let’s check out the 5 most used tools that IDR Solutions suggests to help Java Developers write better code.
FindBugs is an open source program, distributed under the terms of the Lesser GNU Public license and operates on Java bytecode rather than source code. It can identify potential errors in the code of Java programs, such as null pointer dereferences, infinite recursive loops, bad uses of the Java libraries and deadlocks.
FindBugs is mainly used for identifying serious defects in large applications and is capable of determining the severity of potential errors and are classified in ranks(scariest, scary, troubling, of concern). It is available as plug-in for Eclipse, NetBeans, IntelliJ IDEA. It can be used from the command line or within ant, eclipse, maven, netbeans and emacs.
Apache Ant is an open source Apache project, released under the Apache Software License. It uses XML but is implemented in Java and is mainly used for Java projects. It consists of built-in tasks that allow developers to compile, assemble, test and run Java applications.
Ant can also be used in building non Java applications, such as C or C++ applications andgenerally in types of process which can be described in terms of targets and tasks. It is flexible and does not put restrictions on coding conventions or directory layouts for Java projects. It is available for Eclipse, NetBeans, and IntelliJ IDEA.
JProfiler is a commercially licensed Java profiling tool developed by ej-technologies GmbH, mainly designed for use with Java EE and Java SE applications.It can be very useful when developers need to analyze performance bottlenecks, memory leaks, CPU loads and resolve threading issues.
It supports both local and remote profiling, that is analysis of applications running on the same machine or remote machines. It can profile the information in both cases, so users can see live through a visual representation showing the load in terms of active and total bytes, instances, threads, classes, and garbage collector activites.
JProfiler it can be either a stand-alone application or a plug-in for the Eclipse, NetBeans, and IntelliJ IDEA and Orcale JDeveloper software development environments. It is also available as part of application server integration in Adobes Coldfusion and Glassfish.
Bash is a UNIX shell, or command language interpreter, written for the GNU Project as a free software replacement for the Bourne shell. It is used as a command processor, typically running in a text window, and allows for type commands which cause actions. It reads commands from a file and supports filename wildcarding, piping, command substitution, variables. It can control structures for condition-testing and iteration. It is particularly useful as it allows for the automation of some tasks using Bash scripts.
SonarQube is an open source platform that has become a world leader in code quality management systems, and is well known for its Continuous Inspection of code quality.
Bulletproof Java Code: A Practical Strategy for Developing Functional, Reliable, and Secure Java Code
Use Java? If you do, you know that Java software can be used to drive application logic of Web services or Web applications. Perhaps you use it for desktop applications? Or, embedded devices? Whatever your use of Java code, functional errors are the enemy!
To combat this enemy, your team might already perform functional testing. Even so, you're taking significant risks if you have not yet implemented a comprehensive team-wide quality management strategy. Such a strategy alleviates reliability, security, and performance problems to ensure that your code is free of functionality errors.Read this article to learn about this simple four-step strategy that is proven to make Java code more reliable, more secure, and easier to maintain.
