I have been using Java 1.2 and 1.3. People told me that the way we compile (javac) and run (java) our Java programs is now different with Java 1.4. How do we compile and run Java programs with Java 1.4?
Your collegues maybe thinking about using assertions with java 1.4. To compile with assertions enabled use javac -source 1.4 and to run with assertions enabled use java -ea . There are other ways of enabling assertions at runtime, but I do not list them to keep things simple. -Barry
