The iterator() method of the AbstractCollection class in Java is used to return an iterator over the elements contained in this collection.The syntax is as follows −public abstract Iterator iterator()To work with AbstractCollection class in Java, import the following package −import java.util.AbstractCollection;For Iterator, import the following package −import java.util.Iterator;The following is an example to implement the AbstractCollection iterator() method in Java −Exampleimport java.util.Iterator; import java.util.ArrayList; import java.util.AbstractCollection; public class Demo { public static void main(String[] args) { AbstractCollection absCollection = new ArrayList(); absCollection.add("Laptop"); absCollection.add("Tablet"); absCollection.add("Mobile"); ...
Read MoreWhat is StringJoiner class in Java 8?
The StringJoiner class in Java 8 constructs a sequence of characters. This sequence is separated by a delimiter and optionally starting with a supplied prefix and ending with a supplied suffix.The following are the constructors of the StringJoiner class:StringJoiner(CharSequence delimiter): This constructor constructs a StringJoiner with no characters in it and with no prefix or suffix. It used the copy of the supplied delimiter.StringJoiner(CharSequence delimiter, CharSequence prefix, CharSequence suffix) This constructor constructs a StringJoiner with no characters in it. It uses the copies of the supplied prefix, delimiter and suffix.The syntax is as follows:public final class StringJoiner extends ObjectHere, class ...
Read MoreWhat is the difference between Math.ceil() and Math.round() methods in JavaScript?
Math.ceil() and Math.round() methods differ in a way that the former round off a number to its nearest integer in upward direction of rounding(towards the greater value) whereas the latter round off a number to its nearest integer in downward direction of rounding(towards lower value). Let's examine the two methods individually.Math.ceil()Math.ceil() method round off number passed as parameter to its nearest integer so as to get greater value.ExampleIn the below example when a number 5.34 passed as a parameter, Math.ceil() round off it in to 6, which is a greater value than actual number. document.write(Math.ceil(5.34)); ...
Read MoreWhat is dependency injection in PHP?\\n
Dependency injection is a procedure where one object supplies the dependencies of another object. Dependency Injection is a software design approach that allows avoiding hard-coding dependencies and makes it possible to change the dependencies both at runtime and compile time.There are numerous approaches to inject objects, here are couple generally known −Constructor InjectionIn this approach, we can inject an object through the class constructor.ExampleOutput3Setter Injectionwhere you inject the object to your class through a setter function.ExampleBenefits of Dependency InjectionAdding a new dependency is as easy as adding a new setter method, which does not interfere with the existing code.
Read MoreWhat is EOFException in Java? How do we handle it?
While reading the contents of a file in certain scenarios the end of the file will be reached in such scenarios a EOFException is thrown.Especially, this exception is thrown while reading data using the Input stream objects. In other scenarios a specific value will be thrown when the end of file reached.Let us consider the DataInputStream class, it provides various methods such as readboolean(), readByte(), readChar() etc.. to read primitive values. While reading data from a file using these methods when the end of file is reached an EOFException is thrown.ExampleFollowing program demonstrates how to handle the EOFException in Java.import ...

Read MoreA Reluctant qualifier in Java Regular Expressions
The reluctant qualifier starts with the shortest string size as possible. If a match is found by the engine, the process continues to find more matches otherwise the engine adds a character to the searched string section and tries again. This continues until a match is obtained or the string is used up.The regex "B+?" is used to find the match in the string "SkyIsBlue".A program that demonstrates this is given as follows:Exampleimport java.util.regex.Matcher; import java.util.regex.Pattern; public class Demo { public static void main(String args[]) { String regex = "B+?"; String str = ...
Read MoreIntStream findAny() method in Java
The findAny() method of the IntStream class in Java is used to return an OptionalInt describing some element of the stream, or an empty OptionalInt if the stream is empty.The syntax is as follows −OptionalInt findAny()Here, OptionalInt is a container object which may or may not contain an int value.Create an IntStream and add some elements −IntStream intStream = IntStream.of(20, 35, 50, 60, 80, 100);Now, return any of the element of the stream using findAny() in Java −OptionalInt res = intStream.findAny();The following is an example to implement IntStream findAny() method in Java −Exampleimport java.util.*; import java.util.stream.IntStream; public class Demo ...
