As a java developer I often wanted to execute a small piece of code and test it quickly without opening an IDE. Some times the same bit of code we want to execute often and use the result somewhere. May be even we want to share that bit of joy with others. One of the solutions is JDoodle.com.
JDoodle.com helps compile and execute java programs online. It has simple interface. Share your thoughts about JDoodle.com here in comment.
