Read MoreComparison of Exception Handling in C++ and Java
The exception handling feature is present almost any object oriented languages nowadays. In C++ and Java also we can get this kind of feature. There are some similarities between exception handling in C++ and exception handling in Java, like in both languages we have to use the try-catch block. Though there are some difficulties also. These are like below −In C++, we can throw any type of data as exception. Any type of data means primitive datatypes and pointers also. In Java we can only throw the throwable objects. Subclasses of any throwable class will also be throwable.Example#include using ...
Read Moreisnormal() in C++
In this section we will see the isnormal() function in C++. This function is present in the cmath library. This function is used to check whether a number is normal or not. The numbers that are considered as non-normal are zeros, infinity or NAN.This function takes float, double or long double values as argument. Returns 1 if the number is normal, otherwise returns 0.Example#include #include using namespace std; int main() { cout
Read MoreBind function and placeholders in C++
Here we will see the Bind function and the placeholders in C++. Sometimes we need to manipulate the operation of some functions as we need. We can use some default parameters to get some essence of manipulating.In C++11, one new feature is introduced, called the bind function. This helps us to do such manipulating in some easier fashion. To use these features, we have to use header file.Bind functions with the help of placeholders helps to determine the positions, and number of arguments to modify the function according to desired outputs.Placeholders are namespaces which detect the position of a ...

The equals() method is inherited from the AbstractList class in Java. It is used to check the object for equality with this list. It returns TRUE if the object is equal to this list, else FALSE is returned.The syntax is as follows −public boolean equals(Object o)Here, o is the object to be compared for equality with this list.To work with the AbstractSequentialList class in Java, you need to import the following packageimport java.util.AbstractSequentialList;The following is an example to implement AbstractSequentialList equals() method in JavaExampleimport java.util.LinkedList; import java.util.AbstractSequentialList; public class Demo { public static void main(String[] args) { ...
