In subject area: Computer Science Call by Reference is a convention in computer science where the compiler passes an address of the actual parameter to the callee. This means that any changes made to the formal parameter in the callee will also affect the value of the actual parameter in the...
object references are passed by value! A method cannot modify a parameter of a primitive type. A method can change the state of an object parameter. A method cannot make an object parameter refer to a new object.
Methods are by default virtual (overridable) in Java it has to lookup the correct method in a table, called a vtable, for every invocation. This is pretty slow, so optimizing compilers are always trying to reduce the lookup costs involved. One approach we mentioned earlier is inlining, which...

Java Call Stacks and Machine Call Stacks The performance tools collect their data by recording events in the life of each Solaris LWP or Linux thread, along with the call stack at the time of the event. At any point in the execution of any application, the call stack represents where the...

A 'Procedure Call' refers to the process of invoking a procedure in a program, which involves a precall sequence and a postreturn sequence in the caller, as well as a prologue and an epilogue in the callee. It includes evaluating actual parameters and passing implicit arguments, such as the...
