If you are a Java Developer, you probably have heard about these tools. Anyway here you have a top 5 of the most searched and useful tools for those who write code in Java, according to IDR Solutions:
FindBugs is an open source program that is distributed under the terms of the Lesser GNU Public license and operates on Java bytecode rather than source code.
The tool can identify potential types of errors in the code of Java programs, these include null pointer dereferences, infinite recursive loops, bad uses of the Java libraries and deadlocks.
FindBugs is mainly used for identifying hundreds of serious defects in large applications and It is capable of determining the severity of potential errors and are classified in four ranks.
Apache Ant is an Apache project and it is open source software, and is released under the Apache Software License. Apache Ant uses XML and is a useful tool for the automation of software build processes and is implemented using Java language, requires the Java platform and mainly used for Java projects. It is also a library and a command-line tool and Ant is design with a a number of built-in tasks that allow developers to compile, assemble, test and run Java applications.
Outside of Java Ant can also be used in building non Java applications, such as C or C++ applications and in general use can be used in types of process which can be described in terms of targets and tasks.
There are a large number of ready-made commercial or open-source “antlibs” available for users and it is extremely useful as it is flexible and does not put restrictions on coding conventions or directory layouts for Java projects.
JProfiler is a commercially licensed Java profiling tool developed by ej-technologies GmbH, and is mainly designed for use with Java EE and Java SE applications.
JProfiler is a Java profiler combining CPU, Memory and Thread profiling into one application and is useful for developers as it can be used to analyze performance bottlenecks, memory leaks, CPU loads and resolve threading issues.
JProfiler is useful as it supports local profiling (analysis of applications that are running on the same machine on which the JProfiler software is installed) and remote profiling (this is where it allows for the analysis of Java applications which are running on remote machines which JProfiler software is not installed on.).
JProfiler can profile the information in both cases and allow the user to immediately see live through a visual representation showing the load in terms of active and total bytes, instances, threads, classes, and garbage collector activites.
Bash is a UNIX shell, or command language interpreter, written for the GNU Project as a free software replacement for the Bourne shell.
It has been around a reletively long period of time and was released in 1989, and it has been widely distributed as a shell for GNU operating systems and as a default shell on Linux and Mac OS X. Its popularity meant It was ported to Microsoft Windows and to Android through various terminal emulation applications.
Essentialy Bash is used as a command processor, typically running in a text window, and allows for type commands which cause actions. Bash can read various commands from a file, and supports filename wildcarding, piping, here documents, command substitution, variables and 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 which was originally launched in 2007 under the name Sonar, and in recent years as become a world leader in code quality management systems, and is well known for its Continuous Inspection of code quality.
It is useful as it offers fully automated analyses tools and integrates well with Maven, Ant, Gradle and other continuous integration tools. It reports on duplicated code, coding standards, unit tests, code coverage, complex code, potential bugs, comments and design and architecture.
