Static methods
If I have two static methods
method1 - throws an exception
method2 - does not
If method2 calls method1 - how can this compile?
If appears to be compiling with no problems
I thought the calling method would have to have include a try..catch to cover this?

u must be having a the Exception declared in the throws clause of method2 if you are not having a try/catch block.
if a method throws a subclass of java.lang.RuntimeException
Example: NullPointerException is a subclass of RuntimeException, so you don't need to declare that method2 throws it.
class Test {
static void method1() throws NullPointerException {
throw new NullPointerException();
}
static void method2() throws NullPointerException {
method1();
}
public static void main(String[] args) {
method2();
}
}
class Test {
static void method1() throws NullPointerException {
throw new NullPointerException();
}
static void method2() throws NullPointerException {
method1();
}
public static void main(String[] args) {
method2();
}
}

Hi mcgettiu,
>> If appears to be compiling with no problems
If the exception is not a RuntimeException, if the 2 methods are in differents classes, and method1 wasn't throwing any exception when you compiled method2, then try to recompile both classes (delete the .class files to be sure it's recompiled).
