Ways in which Java program is less likely to be compromised
Give two ways in which a Java program is less likely to be compromised than the same program written in C++.

In Java, Primitive and reference data types always passed by value while as in C++ referenced data types are passed by reference.
In Java, we have automatic garbage collection that doesn’t have the concept of Destructor and usage of finalize() is not recommended while have we have to explicitly rely upon destructors and deletete operator to free unused memory.
Exception: An object symbolizing the occurrence of an exceptional circumstance - usually, something which has gone wrong in the smooth running of a program. Exception objects are made from classes which expand the Throwable class.
Primitive Type Abstractions: An effective way to reduce the state space of a program is to replace the primitive types with the corresponding abstractions that encapsulate all the possible operations that are performed on these types. Q : What is Signal Handler Signal Handlers: Signal Handlers: In some operating systems, signal handlers are executed on a thread stack; they “overlay” the current thread execution (which may be used, for example, in combination with setjmp/longjmp to create user-domain lightweight t

1. In what ways are the initialization, repetition test, and update steps alike for a sentinel-controlled loop and an endfile-controlled loop? How are they different? 2. Rewrite the program segment that follows using a for loop: count = 0;
Random Access Memory: Random access memory, or RAM, is the memory whose contents are simply accessible to the processing components of a computer. In specific, the time it takes to read and write to a particular portion of the memory does not based on
Explain Downcast with example: It is a cast towards an object's dynamic kind - that is, `down' the inheritance hierarchy. For illustration: // Downcast from Object to String
Null reference: A value utilized to mean, `no object'. Employed whenever an object reference variable is not referring to the object.
Structured programming: It is a style of programming generally related with languages like FORTRAN, C, Pascal and so forth. Employing structured programming methods, a problem is frequently resolved employing a divide and conquer approach like stepwis
Infinite recursion: Recursion which does not finish. This can effect from any of direct recursion, indirect recursion or the mutual recursion. It is generally the outcome of a logical error, and can consequence in stack overflow.
Stack overflow: Stack overflow takes place whenever too many items are pushed onto a stack with a finite or limited capacity.
