callstack

I would like some help on this matter, Example: public class A { private void foo() { //Who Invoked me } } public class B extends A { } public class C extends A { } public class D { C.foo(); } This is basically the scenario. My question is how can method foo() know who is calling it? EDIT : Basically I am trying to do a database Layer, and in Class A I will create a method that will generate SQL statements. Such statements are dynamically generated by getting the values of all the public properties of the calling class. Easiest way is the following: String className = new Exception()

What can cause a java.lang.StackOverflowError ? The stack printout that I get is not very deep at all (only 5 methods). Check for any recusive calls for methods. Mainly it is caused when there is recursive call for a method. A simple example is public static void main(String... args) { Main main = new Main(); main.testMethod(1); } public void testMethod(int i) { testMethod(i); System.out.println(i); } Here the System.out.println(i); will be repeatedly pushed to stack when the testMethod is called. One of the (optional) arguments to the JVM is the stack size. It's -Xss. I don't know what the

I know that an array decays to a pointer, such that if one declared char things[8]; and then later on used things somewhere else, things is a pointer to the first element in the array. Also, from my understanding, if one declares char moreThings[8][8]; then moreThings is not of type pointer to char but of type "array of pointers to char," because the decay only occurs once. When moreThings is passed to a function (say with prototype void doThings(char thingsGoHere[8][8]) what is actually going on with the stack? If moreThings is not of pointer type, then is this really still a pass-by
