Set Row Header View using the setRowHeaderView() method. Let us first create a KScrollPane and set a list −List myList = new ArrayList(10); for (int index = 0; index < 20; index++) { myList.add("List Item " + index); } final JList list = new JList(myList.toArray(new String[myList.size()])); JScrollPane scrollPane = new JScrollPane(); scrollPane.setViewportView(list);Now, set the row header view −scrollPane.setRowHeaderView(new JLabel("All List Items "));The following is an example to set row header view for JScrollPane in Java −Examplepackage my; import java.awt.BorderLayout; import java.util.ArrayList; import java.util.List; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JList; import javax.swing.JPanel; import javax.swing.JScrollPane; public class SwingDemo { public ...
Read MoreDifference between %p and %x in C/C++
Here we will see what are the differences between %p and %x in C or C++. The %p is used to print the pointer value, and %x is used to print hexadecimal values. Though pointers can also be displayed using %u, or %x. If we want to print some value using %p and %x then we will not feel any major differences. The only difference that can be noticed is that the %p will print some leading zeros, but %x doesn’t.Example#include main() { int x = 59; printf("Value using %%p: %p", x); printf("Value using %%x: %x", x); ...
Read MoreC++ Program to Implement Levenshtein Distance Computing Algorithm
The Levenshtein distance between two strings means the minimum number of edits needed to transform one string into the other, with the edit operations i.e; insertion, deletion, or substitution of a single character.For example: The Levenshtein Distance between cat and mat is 1 −cat mat(substitution of ‘c’ with ‘m’)Here is a C++ Program to implement Levenshtein Distance computing algorithm.AlgorithmsBegin Take the strings as input and also find their length. For i = 0 to l1 dist[0][i] = i For j = 0 to l2 dist[j][0] = j For j=1 to l1 ...

Read MoreC++ Program to Decode a Message Encoded Using Playfair Cipher
In this scheme, pairs of letters are encrypted, instead of single letters as in the case of simple substitution cipher.In playfair cipher, initially a key table is created. The key table is a 5×5 grid of alphabets that acts as the key for encrypting the plaintext. Each of the 25 alphabets must be unique and one letter of the alphabet (usually J) is omitted from the table as we need only 25 alphabets instead of 26. If the plaintext contains J, then it is replaced by I.The sender and the receiver deicide on a particular key, say ‘tutorials’. In a ...

Read Moregetopt() function in C to parse command line arguments
The getopt() is one of the built-in C function that are used for taking the command line options. The syntax of this function is like below −getopt(int argc, char *const argv[], const char *optstring)The opstring is a list of characters. Each of them representing a single character option.This function returns many values. These are like below −If the option takes a value, then that value will be pointed by optarg.It will return -1, when no more options to procesReturns ‘?’ to show that this is an unrecognized option, it stores it to optopt.Sometimes some options need some value, If the ...
