Tech Differences

Interface and Abstract class both contribute to "incomplete type" in OOP. Sometimes we need a superclass to define "what to do" but, not "how to do", it's how to do part will be implemented by the derived class according to its need, "interface" provide a solution to this. Sometimes we need a superclass class that defines some generalised structure that can be implemented by derived classes and some specified structure that can be utilised by the derived classes, "abstract class" provides a … [Read more...]

The throw and throws are the keywords used in exception handling. The throw keyword is used to handover the instance of the exception created by the programmer to the JVM manually. The throws keyword used to handover the responsibility of handling the exception occurred in the method to the caller method. Te basic difference between the throw and throws is that the throw keyword uses the exception object whereas the throws keyword uses the name of the exception classes. Content: throw Vs … [Read more...]

String and StringBuffer both are the classes which operate on strings. StringBuffer class is the peer class of the class String. The object of  String class is of fixed length. The object of the StringBuffer class is growable. The basic difference between String and StringBuffer is that the object of the "String" class is immutable. The object of the class "StringBuffer" mutable. Content: String Vs StringBuffer Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

The words 'final, finally, and finalize' lies within the context of Java. Each one of them is provided a different functioning. The basic difference between final, finally, and finalize is that final is an access modifier, finally is a block and finalize is a method of an object class. There are some other differences between final, finally, and finalize which are discussed in the comparison chart. Content: Final Vs Finally Vs Finalize Comparison Chart Definition Key Differences … [Read more...]

"Throwable" is the parent class of the classes Error and Exception. The class "RuntimeException" and its subclasses, the class "Error" and its child classes are the "Unchecked exceptions" whereas, the remaining subclasses of the class "Exception" except "RuntimeException" are the checked exceptions. The basic difference between checked and unchecked exception is that the checked exceptions are checked by the compiler whereas, the compiler does not check the unchecked exceptions. Let us … [Read more...]

"Throwable" act as the root for Java's error and exception hierarchy. "Error" is a critical condition that cannot be handled by the code of the program. "Exception" is the exceptional situation that can be handled by the code of the program. The significant difference between error and exception is that an error is caused due to lack of system resources, and an exception is caused because of your code. Let us study other differences between error and exception along with a comparison … [Read more...]

Copy constructor and assignment operator, are the two ways to initialize one object using another object. The fundamental difference between the copy constructor and assignment operator is that the copy constructor allocates separate memory to both the objects, i.e. the newly created target object and the source object.The assignment operator allocates same memory location to the newly created target object as well as source object. Let us study the difference between the copy constructor and … [Read more...]

Macro is an instruction which expands at the time of its invocation. Functions can also be defined, like macros. Similarly, the inline functions also expand at the point of its invocation. One primary difference between inline and macro function is that the inline functions are expanded during compilation, and the macros are expanded when the program is processed by the preprocessor. Let's study the difference between inline and macro with the help of comparison chart. Content: Inline Vs … [Read more...]

Recursion and iteration both repeatedly executes the set of instructions. Recursion is when a statement in a function calls itself repeatedly. The iteration is when a loop repeatedly executes until the controlling condition becomes false. The primary difference between recursion and iteration is that is a recursion is a process, always applied to a function. The iteration is applied to the set of instructions which we want to get repeatedly executed. Content: Recursion Vs Iteration … [Read more...]
