Explanation

will compile the program. As for command line: First the code will produce the output: Standard Edition The ea option will enable assertions. This will make the following line in the switch statement to default: assert false; This will throw an assertion error. This error will be caught. An the class of the assertion error (classjava.lang.AssertionError) will be printed by the following line: System.out.println(e.getClass()); Note:The java tool launches a Java application. It does this by starting a Java runtime environment, loading aspecified class, and invoking that class's main method. The method declaration must look like the following: public static void main(String args[]) -enableassertions[:<package name>"..." | :<class name> ] -ea[:<package name>"..." | :<class Enable assertions. Assertions are disabled by default. With no arguments, enableassertions or - ea enablesassertions. An assertion is a statement in the JavaTM programming language that enables you to test your assumptionsabout your program. Each assertion contains a boolean expression that you believe will be true when the assertion executes. If it isnot true, the system will throw an error. public class AssertionError extends Error Thrown to indicate that an assertion has failed. The javac command compiles Java source code into Java bytecodes. You then use the Java interpreter - the java command - to interprete the Java bytecodes.
