HTML DOM Select length Property
The HTML DOM select length property returns the number of elements inside a drop-down list in an HTML document.SyntaxFollowing is the syntax −object.lengthExampleLet us see an example of HTML DOM select length property − html{ height:100%; } body{ text-align:center; color:#fff; background: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%) center/cover no-repeat; height:100%; } p{ font-weight:700; font-size:1.2rem; } .drop-down{ width:35%; border:2px solid #fff; ...
Read MoreUsing Iterations in Python Effectively
In this article, we will learn about how to implement iterators and their effective implementation in Python 3.x. Or earlier. Let’ s take a look at various methods available in python which implements iterators.Type 1 − Implementation Of While Loop With Known LengthExample Codegenre = ("Python", "C", "C++", "Java") print("The topic available on Tutorial's Point are:") i = 0 while (i < len(genre)): print (genre[i]) i += 1ExplanationDue to its less compact structure, this method is not favored. Error Handling is also difficult in this case . Large-scale programs or designs doesn’t use this ...
Read MoreAlgorithmParameterGenerator getAlgorithm() method in Java
The algorithm name for the parameter generator can be obtained using the method getAlgorithm() in the class java.security.AlgorithmParameterGenerator. This method requires no parameters and it returns the algorithm name in string form.A program that demonstrates this is given as follows −Exampleimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) { try { AlgorithmParameterGenerator apGenerator = AlgorithmParameterGenerator.getInstance("DiffieHellman"); apGenerator.init(1024); String algorithm = apGenerator.getAlgorithm(); System.out.println("The Algorithm is: " + algorithm); } catch (NoSuchAlgorithmException e) { ...

The HTML DOM select size property returns and modify the value of the size attribute of a drop-down list.SyntaxFollowing is the syntax −Returning sizeobject.sizeModifying valueobject.size = “number”ExampleLet us see an example of HTML DOM select size property − html{ height:100%; } body{ text-align:center; color:#fff; background: radial-gradient( circle farthest-corner at 23.1% 64.6%, rgba(129, 125, 254, 1) 0%, rgba(111, 167, 254, 1) 90% ) no-repeat; height:100%; } p{ font-weight:700; font-size:1.1rem; } ...
Read MoreIterate over the elements of HashSet in Java
Declare a HashSet and add elements −Set hs = new HashSet(); hs.add(20); hs.add(39); hs.add(67); hs.add(79);Now, iterate over the elements −for (Iterator i = hs.iterator(); i.hasNext();) { Object ele = i.next(); System.out.println(ele); }The following is an example that iterate over the elements of HashSet −Exampleimport java.util.HashSet; import java.util.Iterator; import java.util.Set; public class Demo { public static void main(String[] argv) throws Exception { Set hs = new HashSet(); hs.add(20); hs.add(39); hs.add(67); hs.add(79); System.out.println("Elements = "); for (Iterator i ...
Read MoreProvider get() method in Java
The value to which a key is mapped can be obtained using the get() method in the class java.security.Provider. This method requires a single parameter i.e. the key whose value is required. It returns the value to which the key is mapped or it returns null if there is no value to which the key is mapped.A program that demonstrates this is given as follows −Exampleimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) { try { SecureRandom sRandom = SecureRandom.getInstance("SHA1PRNG"); Provider p = ...
Read MoreRemove duplicate elements in Java with HashSet
Set implementations in Java has only unique elements. Therefore, it can be used to remove duplicate elements.Let us declare a list and add elements −List < Integer > list1 = new ArrayList < Integer > (); list1.add(100); list1.add(200); list1.add(300); list1.add(400); list1.add(400); list1.add(500); list1.add(600); list1.add(600); list1.add(700); list1.add(400); list1.add(500);Now, use the HashSet implementation and convert the list to HashSet to remove duplicates −HashSetset = new HashSet(list1); Listlist2 = new ArrayList(set);Above, the list2 will now have only unique elements.Exampleimport java.util.ArrayList; import java.util.HashSet; import java.util.List; public class Demo { public static void main(String[] argv) { Listlist1 = new ArrayList(); ...
Read MoreNavigableMap clear() Method in Java
Clear the NavigableMap in Java, using the clear() method.Let us first create a NavigableMap and add some elements to it −NavigableMap n = new TreeMap(); n.put(5, "Tom"); n.put(9, "John"); n.put(14, "Jamie"); n.put(1, "Tim"); n.put(4, "Jackie"); n.put(15, "Kurt"); n.put(19, "Tiger"); n.put(24, "Jacob");Now, use the clear() method −n.clear();The following is an example to implement clear() method and clear the NavigableMap −Exampleimport java.util.*; public class Demo { public static void main(String[] args) { NavigableMap n = new TreeMap(); n.put(5, "Tom"); n.put(9, "John"); n.put(14, "Jamie"); n.put(1, "Tim"); ...
Read MoreProvider getName() method in Java
The name of the provider can be obtained using the getName() method in the class java.security.Provider. This method requires no parameter and it returns the name of the provider as required.A program that demonstrates this is given as follows −Exampleimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) { try { KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA"); Provider p = kpGenerator.getProvider(); System.out.println("The Provider is: " + p.getName()); } catch (NoSuchAlgorithmException e) { ...
