The LinkedBlockingQueue Class in Java has a blocking queue that is optionally bounded and based on linked nodes. This means that if the capacity is provided then the LinkedBlockingQueue is bound, otherwise it is not bound. Also, FIFO for ordering elements.A program that demonstrates this is given as follows −Example Live ... Read More

Sorting a vector in C++ can be done by using std::sort(). It is defined in header. To get a stable sort std::stable_sort is used. It is exactly like sort() but maintains the relative order of equal elements. Quicksort(), mergesort() can also be used, as per requirement.AlgorithmBegin    Decalre v of ... Read More

Let’s say the following is our Collection i.e. ArrayList −Listlist = new ArrayList(); list.add(100); list.add(200); list.add(200); list.add(200); list.add(300); list.add(400); list.add(400); list.add(500);Now, create another Collection −List list2 = new ArrayList(); list2.add(100); list2.add(200); list2.add(300); list2.add(400);To remove all elements from a Collection in another Collection, try the following with list and list2 as ...

A duplicate buffer of a buffer can be created using the method duplicate() in the class java.nio.CharBuffer. This duplicate buffer is identical to the original buffer. The method duplicate() returns the duplicate buffer that was created.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public ...

You can use lc_messages to change MySQL error message language. The syntax is as follows −SET lc_messages = 'yourLanguage';To understand the concept, let us create a table with some error and check the error message language.Here, we have set the local message to French. Let us first create a table ... Read More
