Get Resource

Read a file in from a resource. In many cases it is useful to read it into a string. Use a standard Maven directory layout.

Getting Debug Logging with Maven and Cargo

Starting in Maven 3.1.x, logging was switched to SLF4J. The consequence is that you no longer receive DEBUG or TRACE logging messages in a cargo build.

Modify Simple Logger Properties

You can update ${MAVEN_HOME}/conf/logging/simplelogger.properties. But that will create a lot of "noise."

JSON Parsing in C#

In the past I have used Visual Studio for C# and .NET developement. This little project is used to create a simple .NET console program using Visual Studio Code. The goal is to confirm that for multiple value entries, the .NET parser will use the last entered value.

Getting Started

Use these instructions to get the project up and running.

Compare members of different lists in Java

Java Collections has some built-in features; e.g. retainAll and removeAll.

//listOne.retainAll(listTwo);
listOne.removeAll(listTwo);

Note: Sets do not allow duplicates.

OpenJDK on Mac


Follow these instructions to move from an Oracle JDK to OpenJDK. In a twist of irony, I had originally replaced OpenJDK on my Mac with the Oracle JDK!


Remove Oracle JDK


The steps for removing different versions of the JDK vary. This is what I did.


sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
