[email protected]:~$ The operating system synchronously raises a SIGFPE exception, the C program catches it, and then the java constructs and feeds you the ArithmeticException and cleans up after itself to stop public class MainClass { public static void main(String args[]) { int urAns, urDiv; try { urDiv = 0; urAns = 25 / urDiv; System.out.println("Do you really think this will print out? weblink

Our prior examples that read numeric values from the user assumed that the user would input a proper integer value. The JVM's handler instead issues the (catchable) RuntimeException so that these exceptions can be handled in a native-seeming way.
