Check whether two HashSet are equal in Java
At first, create the first HashSet and add elements to it −// create hash set 1 HashSet hs1 = new HashSet(); hs1.add("G"); hs1.add("H"); hs1.add("I"); hs1.add("J"); hs1.add("K");Create the second HashSet and add elements to it −// create hash set 2 HashSet hs2 = new HashSet(); hs2.add("G"); hs2.add("H"); hs2.add("I"); hs2.add("J"); hs2.add("K");To check whether both the HashSet are equal or not, use the equals() method −hs1.equals(hs2)The following is an example to check whether two HashSet are equal −Exampleimport java.util.*; public class Demo { public static void main(String args[]) { // create hash set 1 ...
Read MoreDoubleStream anyMatch() method in Java
The anyMatch() method of the DoubleStream class returns whether any elements of this stream match the provided predicate.The syntax is as followsboolean anyMatch(DoublePredicate predicate)Here, the parameter predicate is a stateless predicate to apply to elements of this stream. The DoublePredicate here is a predicate of one double-valued argument.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;Create a DoubleStream and add some elements to the streamDoubleStream doubleStream = DoubleStream.of(67.9, 89.9, 10.5, 95.8, 49.6);Now, check if any of the elements match the predicateboolean res = doubleStream.anyMatch(a -> a > 50);The following is an example to implement DoubleStream anyMatch() method ...
Read MoreC++ Program to use above below primitive to test whether two lines intersect
Here is a C++ program to use above below primitive to test whether two lines intersect. It can be used to test whether a line intersects a line segment. It does if and only if one endpoint of the segment is to the left of the line and the other is to the right.AlgorithmBegin For generating equation of the first line, generate random numbers for coefficient of x and y by using rand at every time of compilation. For generating equation of the second line, generate random numbers for coefficient of x and y by using rand at ...

The codePoint() method is used to display a stream of code point values from the given sequence.The syntax is as followsIntStream codePoints()To work with Java IntStream class, you need to import the following packageimport java.util.stream.IntStream;Here is our stringString myStr = "Example!";Now, get the code point valuesIntStream intStream = myStr.codePoints();The following is an example to implement codePoints() method in Java IntStreamExampleimport java.util.stream.IntStream; public class Demo { public static void main(String args[]) { String myStr = "Example!"; IntStream intStream = myStr.codePoints(); System.out.println("The following is the list of ASCII Values for the given ...
Read MoreCopy all the elements from one set to another in Java
Use the clone() method to copy all elements from one set to another.First HashSet −HashSet set = new HashSet (); set.add("One"); set.add("Two");Create another set and clone first set into the second −HashSet newSet = new HashSet ();Copy (clone) all elements to the second set −newSet = (HashSet)set.clone();The following is an example to copy all elements from one set to another −Exampleimport java.util.*; public class Demo { public static void main(String args[]) { HashSet set = new HashSet (); HashSet newSet = new HashSet (); set.add("One"); ...

The remove() method of the ArrayBlockingQueue class in Java is used to remove a single instance of the specified element from this queue.The syntax is as followsboolean remove(Object ele)Here, ele is the element to be removed from the queue. To work with ArrayBlockingQueue class, you need to import the following packageimport java.util.concurrent.ArrayBlockingQueue;The following is an example to implement remove() method of Java ArrayBlockingQueue classExampleimport java.util.ArrayList; import java.util.Iterator; import java.util.concurrent.ArrayBlockingQueue; public class Demo { public static void main(String[] args) throws InterruptedException { ArrayBlockingQueue q = new ArrayBlockingQueue(10); q.add(120); q.add(10); ...
Read MoreFind maximum element of HashSet in Java
To get the maximum element of HashSet, use the Collections.max() method.Declare the HashSet −Set hs = new HashSet();Now let us add the elements −hs.add(29); hs.add(879); hs.add(88); hs.add(788); hs.add(456);Let us now get the maximum element −Object obj = Collections.max(hs);The following is an example to find maximum element of HashSet −Exampleimport java.util.*; public class Demo { public static void main(String args[]) { // create hash set Set hs = new HashSet(); hs.add(29); hs.add(879); ...
Read MoreIntStream limit() method in Java
The limit() method of the IntStream class is used to return a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length. Here, maxSize is the parameter.The syntax is as followsIntStream limit(long maxSize)Here, the maxSize parameter is the count of elements the stream is limited to.At first, an IntStream is created with the range() method to set a sequential order of elementsIntStream intStream = IntStream.range(20, 40);Now, use the limit() method, whose parameter is the maxSize i.e. the count of elements the stream is limited tointStream.limit(8)The following is an example to implement IntStream limit() ...
