This is my code
class HelloWorldApp {
public static void main(String[] args) {
System.out.println("Hello World!"); // Display the string.
}
}
Your compiler is newer than your JRE. Try this:
javac -version
java -version
that means that you compiled it using 5 or 6, and are running it using an old version.
java -version// what version runtime is
javac -version // what version compiler is
