Here are some theory-based basic programming problems Java:
1) Differences Between C++ and Java
Concept:
- C++: Not platform-independent, follows “write once, compile anywhere.”
- Java: Platform-independent byte code allows programs to run on any machine.
Languages Compatibility:
- C++: Compatible with most high-level languages.
- Java: Incompatible with most languages, comparable to C and C++.
Interaction with the Library:
- C++: Direct access to native system libraries, suitable for system-level programming.
- Java: Requires Java Native Interface or library access, not direct call support.
Characteristics:
- C++: Combines features of procedural and object-oriented languages.
- Java: Known for automatic garbage collection, lacks support for destructors.
Semantics of the Type:
- C++: Consistent semantics for primitive and object types.
- Java: Inconsistent semantics between primitive and object types and classes.
Compiler and Interpreter:
- Java: Compiled and interpreted language, source code compiles into platform-independent bytecode.
- C++: Purely compiled language, source program compiles into object code, further executed.
2) Features of the Java Programming Language:
- Easy: Java is considered easy to learn, with fundamental Object-Oriented Programming (OOP) concepts.
- Secured Feature: Java provides a secured feature, ensuring the development of virus-free and tamper-free systems.
- OOP: Java follows Object-Oriented Programming, treating everything as an object.
- Independent Platform: Java compiles into platform-independent bytecode, interpreted by the Virtual Machine.
3) ClassLoader in Java:
- A ClassLoader in Java is a subsystem of the Java Virtual Machine responsible for loading class files during program execution.
- It is the first to load the executable file and includes Bootstrap, Extension, and Application classloaders.
4) Differences Between Heap and Stack Memory in Java:
- Stack Memory: Allocated to each individual program. Fixed memory space.
- Heap Memory: Not assigned to Java code initially but available during runtime. Used as needed by the Java code.
