The novice veteran can not leave the eight development tools

Many libraries, utilities, and programs are now available to Java developers. Each tool has its advantages, but some of them stand out from many options because of its popularity, versatility, and effectiveness.

The following 8 tools, from code building to error squeezing, cover the entire domain of Java development. Learning these tools can help you improve the quality of your code and become a more efficient Java developer.

1.Eclipse

Although IntelliJ idea, NetBeans, and some other Ides are gaining popularity, a survey shows that eclipse is still the preferred development environment for almost half of Java developers. Eclipse is the Swiss Army knife in the IDE, with a large number of custom interfaces and countless plugins. It is ubiquitous, and the Eclipse plugin is available in all other tools that this article will recommend.

Eclipse's workflow can be divided into three areas: Workbench, Workspace, and perspective. Workbench as a starting point to the IDE. Workspaces combine project, file, and configuration settings in a separate directory. Perspective defines tools, views, and valid settings. While novice developers may find it harder to use than NetBeans and IntelliJ Idea,eclipse, Eclipse's flexibility makes it the preferred IDE for enterprise development.

2.Gradle

Gradle is an automated project tool built on the capabilities of Apache Maven and Apache Ant. Although Gradle is not a very popular build tool (the super-popular is the Java developer of maven,64% will choose it), it's popularity is fast. It can also be used as the default Android build tool.

Gradle was proud of its simplicity. Gradle uses the Groovy programming language, which is diametrically opposed to the use of XML syntax by maven and Ant. A basic Gradle build file consists of a simple line of code:

3.Javadoc

The Javadoc is a document generator provided by Oracle. It can parse special-format annotations into HTML documents. The following is the Java SE 8 API specification generated by Javadoc:

Javadoc annotations Use open tags, close labels, and the format of one or more descriptive labels. An open label is similar to a standard Java multiline comment tag, with the exception of two asterisks. Javadoc also parses ordinary HTML tags.

Javadoc automatically formats labels and keywords, unless otherwise specified. Javadoc uses hyperlinks extensively, allowing you to refer to and link to different areas of your code. Many ide--include eclipse--can automatically add Javadoc annotation modules to variables, classes, and methods. Plugins that support Maven, Gradle, and Ant can build Javadoc HTML while compiling code.

4.JUnit

JUnit is an open-source framework for writing and running unit tests. A basic JUnit test includes test classes, test methods, and the ability to perform tests. JUnit uses annotations to determine how tests are constructed and run. For example, if your program has a class called MathClass, which has methods for multiplication and division, you can create JUnit tests to check for values that do not meet expectations. Enter the numbers 2 and 5 into the multiplication method, and you want the result to be 10. When you enter 0 as the second parameter of the division method, you expect to give a warning that the number calculates the exception because the divisor cannot be 0:

@Test labeling rules, the MathClass method is a test case. Provide additional annotations in JUnit, such as @before, so you can set the environment before the test runs. JUnit can also set rules to define the behavior of test methods. For example, the Temporaryfolder rule allows a file or folder created by the test to be deleted once the test is complete.

5.Cobertura

Cobertura can be used to analyze test coverage of Java code. Cobertura generates HTML-based reports based on code that is not covered by the test.

Cobertura provides tools that you can use to plug in, inspect, and test code. By monitoring testable code, Cobertura allows you to run your program using the test framework you choose, without even needing to test the framework.

Cobertura provides code coverage reports based on lines, branches, and packages. Each category has a customizable threshold that triggers a warning if the coverage falls below the threshold. The Cobertura also integrates the automatic detection capabilities of MAVEN and Gradle.

6.FindBugs

FindBugs is a tool that matches the compiled code pattern rather than using the bug database. FindBugs can also highlight lines of code that detect bugs when the source code is provided.

In its version 3.0.1, FindBugs continues to maintain hundreds of bug descriptions. Depending on the severity of the bug, FindBugs divides the bug into four levels: related, disturbing, scary, and most frightening. In addition to the graphical user interface, FindBugs also provides a command line interface, ant tasks, and Eclipse plugins.

7.VisualVM

The VISUALVM included in the JDK is a tool for monitoring and reviewing the performance of Java applications. VISUALVM detects and attaches importance to the active JVM instance to retrieve diagnostic information about the process.

VISUALVM can easily diagnose performance problems in real time. It provides a full suite of analytical tools, including Jconsole, Jstack, Jmap, Jinfo, and Jstat. In addition, you can take a snapshot of the JVM so that it can be reviewed at any time later.

8.Groovy

Groovy is a programming language that simplifies and extends Java by adding new keywords, automatically importing commonly used classes, and optional type variable declarations.

One of the core strengths of groovy is its scripting capabilities. Classes can be compiled into Java bytecode or executed dynamically using groovy shell. Groovy's Java base makes it easier for Java developers to accept than Jython and JRuby
