A bunch of recurrent Java mathematical functions on arrays you are tired to implement again and again.
The library is made of a single abstract class ArrayUtils
with a number of static methods.
Latest version is 0.1
, corresponding to git tag v0.1
. Follow instructions below to add it as a dependency to your project.
First add the maven url to the repositories in your build.gradle
:
repositories {
// Possibly other repos
maven {
url "https://dl.bintray.com/mziccard/maven/"
}
}
And then add the library as a dependency:
dependencies {
compile group: 'me.mziccard', name: 'array-utils', version: '0.1'
}
Add the bintray maven repository to your resolvers as:
resolvers += Resolver.bintrayRepo("mziccard", "maven")
And then add the library as a dependency:
libraryDependencies ++= Seq("me.mziccard" %% "array-utils" % "0.1")
Add the bintray repository to your Maven configuration:
<repositories>
<repository>
<snapshots>
<enabled>false</enabled>
</snapshots>
<id>bintray-mziccard-maven</id>
<name>bintray</name>
<url>http://dl.bintray.com/mziccard/maven</url>
</repository>
</repositories>
An then add the library as a dependency:
<dependency>
<groupId>me.mziccard</groupId>
<artifactId>array-utils</artifactId>
<version>0.1</version>
<type>jar</type>
</dependency>
Follows a list of the available static methods, in the following T
