Java Project / Library to evaluate poker hands

I have some experience with Java but I would still consider myself a beginner. I recently came across this link: http://github.com/phstc/javapokertexasholdem
The link contains folder and files to a texas holdem card evaluator library/project. The folders are named: .settings, src, test and the files are named: .classpath, .gitignore, .project, README.rdoc, pom.xml.
The folder src and test contain actual java code this part I get (80% of it), but the .settings folder contains files named: org.eclipse.jdt.core.prefs and org.maven.ide.eclipse.prefs.

Are these files meant for the Eclipse IDE? Do I need them for proper operation of the code in src and test? If so, could you explain briefly what they do? Is it possible to use these folders and files (other than src and test) in the NetBeans IDE?

Here are the contents of org.eclipse.jdt.core.prefs.

Code :

eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5
org.eclipse.jdt.core.compiler.codegen.unusedLocal=preserve
org.eclipse.jdt.core.compiler.compliance=1.5
org.eclipse.jdt.core.compiler.debug.lineNumber=generate
org.eclipse.jdt.core.compiler.debug.localVariable=generate
org.eclipse.jdt.core.compiler.debug.sourceFile=generate
org.eclipse.jdt.core.compiler.problem.assertIdentifier=error
org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning
org.eclipse.jdt.core.compiler.source=1.5

Here are the contents of org.maven.ide.eclipse.prefs.

Code :

activeProfiles=
eclipse.preferences.version=1
fullBuildGoals=process-test-resources
includeModules=false
resolveWorkspaceProjects=true
resourceFilterGoals=process-resources resources\:testResources
skipCompilerPlugin=true
version=1

Here are the contents of .classpath

Code :

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" output="target/classes" path="src"/>
<classpathentry kind="src" output="target/test-classes" path="test"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"/>
<classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/>
<classpathentry kind="output" path="target/classes"/>
</classpath>

Here are the contents of .gitignore

Code :

.DS_Store
*~
*.swp
*.class
mkmf.log
target/*
stats*.csv
*.settings*

Here are the contents of .project

Code :
