[JavaBean]

Java console applications do no open a console by default. If you are running your application by double clicking on its jar, this is not correct way to see console output.

You will need to open a DOS window and type something like this if it is the output is a jar file:

Code:

java -jar yourJarName.jar

If it is a class instead of jar, run it as follows:

Code:

java YourClassName
