I am writing a java applicaiton that outputs strings via System.out and I just want to know how to run this application outside my IDE. I have an executable jar. What does one do to see this output in a console?

To run an application in a nonexecutable JAR file, we have to use -cp option instead of -jar. We'll use the -cp option (short for classpath) to specify the JAR file that contains the class file we want to execute: java -cp jar-file-name main-class-name [args …]
jar file from the Linux terminal. To do this, you must have java command line tool installed to launche a Java application, and the -jar flag to execute a program encapsulated in a JAR file. When this flag is used, the specified JAR file is the source of all user classes, and other class path settings are ignored.
Basically: java -jar app.jar

As others have suggested:
java -jar JarFIle.jar
Note this requires you to set the main class entry point
If you don't/can't set Main-Class then you would do:
java -cp JarFile.jar package.Classname
Additionally if you associate jar file types with your JRE then double click should work too.
