If it is a .java file editable in gedit you will have to compile it first, for this use javac xyz.java, if javac doesn't work install the JDK. Then to execute it navigate using cd to the location the .class file genearated by javac xyz.java and type java xyz (the .class is not nesscary, however you must be in the location of the file), this will execute the program. If you are planning to develop java I would reccomend downloading eclipse or netbeans from the software center, as these provide syntax highlighting and will compile and run the program at the push of a button.
