To get the size of HashSet, use the size() method. Let us create a HashSet and add elements −Set hs = new HashSet(); hs.add(15); hs.add(71); hs.add(82); hs.add(89); hs.add(91);Let us now use size() and get the size of HashSet −hs.size()The following is an example to get the size of HashSet −Example Live Demoimport java.util.*; public class Demo {    public static void main(String args[]) {       Set hs = new HashSet();       hs.add(15);       hs.add(71);       hs.add(82);       hs.add(89);       hs.add(91);       System.out.println("Elements = "+hs);       ...

To remove specified element from HashSet, use the remove() method.First, declare a HashSet and add elements −Set hs = new HashSet(); hs.add(20); hs.add(39); hs.add(67); hs.add(79); hs.add(81); hs.add(87); hs.add(88);Let’s say you need to remove element 39. For that, use the remove() method −hs.remove(39);The following is an example to remove specified element from HashSet −Example Live Demoimport java.util.*; public class Demo {    public static void main(String args[]) {       Set hs = new HashSet();       hs.add(20);       hs.add(39);       hs.add(67);       hs.add(79);       hs.add(81);       hs.add(87);     ...

The function isless() is used to check that first argument is less than the second one. It is declared in “math.h” header file in C language. It returns true if successful otherwise it returns false.Here is the syntax of isless() in C language, bool isless(value1 , value2);Here, value1 − This is the first argument which will be checked with value2.value2 − This is the second argument which is used to check value1 ans see that it is less or not.Here is an example of isless() in C language, Example Live Demo#include #include int main() {    int val1 = 48; ...

Use the font-size-adjust property to preserve the readability when font fallback occurs. You can try to run the following code to implement the font-size-adjust propertyExampleLive Demo                    #demo {             font-size-adjust: 0.90;          }                     Heading Two       With font-size-adjust property:                This is demo text.             Without font-size-adjust property:       This is demo text.
