Create Octet Tuple from another collection in Java
You can create Octel Tuple from another collection i.e. List or arrays. For List, use the fromCollection() method.Let us first see what we need to work with JavaTuples. To work with Octet class in JavaTuples, you need to import the following package −import org.javatuples.Octet;Note: Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuples −Steps: How to run JavaTuples program in EclipseThe following is an ...

A Binary Search Tree is a sorted binary tree in which all the nodes will have following properties−The right sub-tree of a node has a key greater than to its parent node's key.The left sub-tree of a node has a key lesser than to its parent node's key.All key values are distinct.Each node cannot have more than two children.Class Descriptions:Begin class BST to declare following functions: search() = To search an item in BST. initialize temp = root; while(temp != NULL) Increase ...

This is a C++ Program to implement Network_Flow problem using Ford Fulkerson algorithm.Algorithms:Begin function bfs() returns true if there is path from source s to sink t in the residual graph which indicates additional possible flow in the graph. End Begin function fordfulkarson() return maximum flow in given graph: A) initiate flow as 0. B) If there is an augmenting path from source to sink, add the path to flow. C) Return flow. EndExample Code#include #include #include #include #define n 7 using namespace std; bool bfs(int g[n][n], int s, int ...

You can also iterate through Quartet class like Arrays using a loop.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;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 External Jars and upload the downloaded JavaTuples jar file.The following is an example −Exampleimport org.javatuples.Quartet; public class Demo { public static void main(String[] args) { ...
Read MoreWhat do the id and scope attribute mean in the action elements in JSP?
These are two attributes that are common to all Action elements: the id attribute and the scope attribute.Id attributeThe id attribute uniquely identifies the Action element and allows the action to be referenced inside the JSP page. If the Action creates an instance of an object, the id value can be used to reference it through the implicit object PageContext.Scope attributeThis attribute identifies the lifecycle of the Action element. The id attribute and the scope attribute are directly related, as the scope attribute determines the lifespan of the object associated with the id. The scope attribute has four possible values:(a) ...

This is a C++ Program to Implement the Edmonds-Karp algorithm to calculate maximum flow between source and sink vertex.Algorithm:Begin function edmondsKarp() : initiate flow as 0. If there is an augmenting path from source to sink, add the path to flow. Return flow. EndExample Code#include #include #include #include #include using namespace std; int c[10][10]; int flowPassed[10][10]; vector g[10]; int parList[10]; int currentPathC[10]; int bfs(int sNode, int eNode)//breadth first search { memset(parList, -1, sizeof(parList)); memset(currentPathC, 0, sizeof(currentPathC)); queue q;//declare queue vector q.push(sNode); parList[sNode] = -1;//initialize parlist’s ...

For converting array to 1D and 2D arrays, let us first create a one-dimensional and two-dimensional array −One-DimensionalString str[] = {"p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"};Two-Dimensionaldoubled [][]= { {1.2, 1.3, 2.1, 4.1}, {1.5, 2.3}, {2.5, 4.4}, {3.8}, {4.9}, {3.2, 2.1, 3.2, 7.2} };Converting array to string for one-dimensional array −Arrays.toString(str);Converting array to string for two-dimensional array −Arrays.deepToString(d);Exampleimport java.util.Arrays; public class Demo { public static void main(String args[]) { String str[] = {"p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}; ...
Read MoreWhat is the function of action in JSP?
This action lets you insert files into the page being generated. The syntax looks like this −Unlike the include directive, which inserts the file at the time the JSP page is translated into a servlet, this action inserts the file at the time the page is requested.Following table lists out the attributes associated with the include action −S.No.Attribute & Description1pageThe relative URL of the page to be included.2flushThe boolean attribute determines whether the included resource has its buffer flushed before it is included.ExampleLet us define the following two files (a)date.jsp and (b) main.jsp as follows −Following is the content of ...

Here is a C++ Program to implement First Fit Decreasing for 1-D objects and M binsRequired functions and pseudocode:Begin function binPack() returns number of bins required. Initialize binC = 0 Initialize an array to store binVal. Place items one by one. function sort() to perform bubble sort in the descending order. EndExample Code#include using namespace std; void binPack(int *a, int s, int n) { int binC = 0; int binVal[n]; for (int i = 0; i < n; i++) binVal[i] = s; for (int i = 0; i < ...
Read MoreWhat are JSP declarations? In how many ways we can write JSP declarations?
A declaration declares one or more variables or methods that you can use in Java code later in the JSP file. You must declare the variable or method before you use it in the JSP file.Following is the syntax for JSP Declarations −You can write the XML equivalent of the above syntax as follows − code fragment Following is an example for JSP Declarations −
