The count() method of the IntStream class in Java returns the count of elements in this streamThe syntax is as followslong count()First, create an IntStream and add some elementsIntStream intStream = IntStream.of(30, 13, 67, 56, 89, 99, 76, 56);Now, get the count of elements of the stream using the count() methodlong num = intStream.count();The following is an example to implement IntStream count() method in JavaExample Live Demoimport java.util.*; import java.util.stream.IntStream; public class Demo {    public static void main(String[] args) {       IntStream intStream = IntStream.of(30, 13, 67, 56, 89, 99, 76, 56);       long num = ...

The IntStream min() method in the Java IntStream class is used to get the minimum element from the stream. It returns an OptionalInt describing the minimum element of this stream, or an empty optional if this stream is empty.The syntax is as followsOptionalInt min()Here, OptionalInt is a container object which may or may not contain an int value.Create an IntStream and add some elementsIntStream intStream = IntStream.of(89, 45, 67, 12, 78, 99, 100);Now, get the minimum element of the streamOptionalInt res = intStream.min();The following is an example to implement IntStream min() method in Java. The isPresent() method of the OptionalInt ... Read More

The forEach() method of the LongStream class in Java performs an action for each element of this stream.The syntax is as followsvoid forEach(LongConsumer action)Here, the parameter action is a non-interfering action to perform on the elements. LongConsumer represents an operation that accepts a single long-valued argument and returns no result.To use the LongStream class in Java, import the following packageimport java.util.stream.LongStream;The following is an example to implement LongStream forEach() method in JavaExample Live Demoimport java.util.*; import java.util.stream.LongStream; public class Demo { public static void main(String[] args) { LongStream longStream = LongStream.of(1000L, 12000L, ...

The lastIndexOf() method of the AbstractList return the index of the last occurrence of an element in the list. If the element does not exist in the list, then -1 is returned.The syntax is as followspublic int lastIndexOf(Object ob)Here, the parameter ob is the element to be searched. To work with the AbstractList class, import the following packageimport java.util.AbstractList;The following is an example to implement lastIndexOf() method of the AbstractlList class in JavaExample Live Demoimport java.util.ArrayList; import java.util.AbstractList; public class Demo {    public static void main(String[] args) {       AbstractList myList = new ArrayList();       myList.add(75); ...

The skip() method of the IntStream class in Java returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream.The syntax is as followsIntStream skip(long n)Here, n is the number of elements to skip. The method returns the new stream.Create an IntStream and add some elements within a range using range() methodIntStream intStream = IntStream.range(20, 40);Now to skip some elements and only display the rest of them, use the skip() methodintStream.skip(15)The following is an example to implement IntStream skip() method in Java. It skips 15 elements since we have set the ... Read More

The generate() method in the IntStream class returns an infinite sequential unordered stream where each element is generated by the provided IntSupplier.The syntax is as followsstatic IntStream generate(IntSupplier i)Here, i is the IntSupplier for generated elements. The IntSupplier represents a supplier of int-valued results.The following is an example to implement IntStream generate() method in Java. We have used the limit() method here as well to limit the number of elements we want from the streamExample Live Demoimport java.util.*; import java.util.stream.IntStream; public class Demo {    public static void main(String[] args) {       IntStream intStream = IntStream.generate(()       ...

The allMatch() method of the IntStream class in Java returns whether all elements of this stream match the provided predicate.The syntax is as followsboolean allMatch(IntPredicate predicate)Here, the predicate parameter is a stateless predicate to apply to elements of this stream. The IntPredicate represents a predicate of one int-valued argument.The allMatch() method returns true if either all elements of the stream match the provided predicate or the stream is empty.The following is an example to implement IntStream allMatch() method in JavaExample Live Demoimport java.util.*; import java.util.stream.IntStream; public class Demo { public static void main(String[] args) { ...

To search for a value in KeyValue Tuple, use the contains() method. Here, the value to be searched should be set as the parameter of the method. The return value is a boolean i.e. TRUE, if the value exists, else FALSE. Let us first see what we need to work with JavaTuples. To work with KeyValue class in JavaTuples, you need to import the following packageimport org.javatuples.KeyValue;Note Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples ... Read More

To set value in the JavaTuples KeyValue class, you need to use the setValue() method. Let us first see what we need to work with JavaTuples.

Refer the below guide for all the steps to run JavaTuplesSteps: How to run JavaTuples program in EclipseThe following is an example to set ... Read More

The anyMatch() method in the IntStream class in Java returns whether any elements of this stream match the provided predicate.The syntax is as followsboolean anyMatch(IntPredicate predicate)To work with the IntStream class in Java, import the following packageimport java.util.stream.IntStream;Here, the predicate parameter is a stateless predicate to apply to elements of this stream.Create an IntStream and add some elementsIntStream intStream = IntStream.of(20, 40, 60, 80, 100);Now, use the anyMatch() method to set for a condition. If any of the element match with the condition, TRUE is returnedboolean res = intStream.anyMatch(a -> a < 50); The following is an example to implement ... Read More
