How to apply forEach tag in JSP?
The tag is a commonly used tag because it iterates over a collection of objects. The tag is used to break a string into tokens and iterate through each of the tokens.AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultitemsInformation to loop overNoNonebeginElement to start with (0 = first item, 1 = second item, ...)No0endElement to end with (0 = first item, 1 = second item, ...)NoLast elementstepProcess every step itemsNo1varName of the variable to expose the current itemNoNonevarStatusName of the variable to expose the loop statusNoNoneExample for Tag Example Item The above code will generate the following result −Item 1 Item 2 Item 3 Item 4 Item 5
Read MoreWhat are advantages of using JSP?
Following table lists out the other advantages of using JSP over other technologies −vs. Active Server Pages (ASP)The advantages of JSP are twofold. First, the dynamic part is written in Java, not Visual Basic or other MS specific language, so it is more powerful and easier to use. Second, it is portable to other operating systems and non-Microsoft Web servers.vs. Pure ServletsIt is more convenient to write (and to modify!) regular HTML than to have plenty of println statements that generate the HTML.vs. Server-Side Includes (SSI)SSI is really only intended for simple inclusions, not for "real" programs that use form ...
Read MoreWhat is a reentrant function in C/C++?
Here we will see what is the reentrant function in C or C++. One function is said to be a reentrant function if there is a provision to interrupt that function in the course of execution, then service the ISR (Interrupt Service Routine) and then resume the task. This type of functions is used in different cases like, recursions, hardware interrupt handling.For a reentrant function there should be some properties. These are listed below −This type of function will not use any global or static variable. There are no restrictions, but it is generally not advised. This is because the ...

Read MoreWhat's the difference between __PRETTY_FUNCTION__, __FUNCTION__, __func__ in C/C++?
Here we will see what are the differences between __FUNCTION__, __func__ and the __PRETTY_FUNCTION__ in C++.Basically the __FUNCTION__ and __func__ are same. Some old versions of C and C++ supports __func__. This macro is used to get the name of the current function. The _PRETTY_FUNCTION__ is used to return the detail about the function. Using this we can get which function is used, and in which class it is belonging, etc.Example#include using namespace std; class MyClass{ public: void Class_Function(){ cout
Read MoreHow to setup a Web server like Tomcat to test JSP pages?
Apache Tomcat is an open source software implementation of the JavaServer Pages and Servlet technologies and can act as a standalone server for testing JSP and Servlets, and can be integrated with the Apache Web Server. Here are the steps to set up Tomcat on your machine −Download the latest version of Tomcat from https://tomcat.apache.org/.Once you downloaded the installation, unpack the binary distribution into a convenient location. For example, in C:\apache-tomcat-5.5.29 on windows, or /usr/local/apache-tomcat-5.5.29 on Linux/Unix and create CATALINA_HOME environment variable pointing to these locations.Tomcat can be started by executing the following commands on the Windows machine −%CATALINA_HOME%\bin\startup.bat ...
Read MoreC++ Program to Implement Dijkstra's Algorithm Using Set
This is a C++ Program to Implement Dijkstra’s Algorithm using Set. Here we need to have two sets. We generate a shortest path tree with given source node as root. One set contains vertices included in shortest path tree and other set includes vertices not yet included in shortest path tree. At every step, we find a vertex which is in the other set (set of not yet included) and has minimum distance from source.Algorithm:Begin function dijkstra() to find minimum distance: 1) Create a set Set that keeps track of vertices included in shortest path tree, Initially, ...
Read MoreC++ Program to Perform Greedy Coloring
Here is a C++ Program to Perform Greedy ColoringAlgorithm:Begin Take the number of vertices and edges as input. Create function greedyColoring() to assign color to vertices: A) Assign the first color to first vertex. B) Initialize the remaining vertices. C) Declare a temporary array to store the available colors. D) Assign color to the remaining vertices. Print the solution. EndExample Code#include #include using namespace std; int n,e,i,j; vector g; vector col; bool visit[1001]; void greedyColoring() { col[0] = 0; for (i=1;i
Read MoreAdd a value to Quartet class in JavaTuples
To add a value to the Quartet Tuple, use the addAtX() method. The index can be set here with the X i.e. the place where the value gets added.Let us first see what we need to work with JavaTuples. To work with Quartet class in JavaTuples, you need to import the following package −import org.javatuples.Quartet;We will use Quintet class; therefore, we will import the following package −import org.javatuples.Quintet;Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Quartet Class in JavaTuples, then Right Click Project → Properties → Java Build Path → Add ...
Read MoreWhat is difference between int and const int& in C/C++?
Here we will see what are the differences between int and const_int& in C or C++.The int is basically the type of integer type data. And const is used to make something constant. If there is int& constant, then it indicates that this will hold the reference of some int type data. This reference value is constant itself. So the const is redundant. The compiler may return warning or some error.The const int& is same as int const&. So this refers to a constant integer. The integer cannot be modified through the reference.
