The toConcurrentMap() method in Java, part of the java.util.stream.Collectors class, is used to collect elements of a stream into a ConcurrentMap. This method is useful when you need to produce a map where concurrent modifications are supported.
The toCollection() method in Java, part of the java.util.stream.Collectors class, is used to collect the elements of a stream into a specified collection. This method is useful when you need to control the type of collection that the stream elements are collected into.
The teeing() method in Java, part of the java.util.stream.Collectors class, is used to combine the results of two different collectors into a single result. This method is useful when you need to perform two different collection operations on the same stream and then merge the results.
The summingDouble() method in Java, part of the java.util.stream.Collectors class, is used to calculate the sum of a double-valued function applied to the elements of a stream. This method is useful when you need to compute the sum of certain properties of the elements in a stream.
The summarzingInt() method in Java, part of the java.util.stream.Collectors class, is used to collect statistical summary information about the integer elements of a stream. This method is useful when you need to compute summary statistics such as count, sum, min, average, and max for a collection of elements.
The summarizingDouble() method in Java, part of the java.util.stream.Collectors class, is used to collect statistical summary information about the elements of a stream. This method is useful when you need to compute summary statistics such as count, sum, min, average, and max for a collection of elements.
The reducing() method in Java, part of the java.util.stream.Collectors class, is used to perform a reduction on the elements of a stream, producing a single result. This method is useful when you need to combine the elements of a stream into a single summary result, such as the sum of all elements.
The partitioningBy() method in Java, part of the java.util.stream.Collectors class, is used to partition elements of a stream into two groups based on a given predicate. This method is useful when you need to divide elements into two categories based on a boolean condition.
The minBy() method in Java, part of the java.util.stream.Collectors class, is used to find the minimum element of a stream according to a specified comparator. This method is useful when you need to determine the smallest element in a collection based on specific criteria.
The maxBy() method in Java, part of the java.util.stream.Collectors class, is used to find the maximum element of a stream according to a specified comparator. This method is useful when you need to determine the largest element in a collection based on specific criteria.
The mapping() method in Java, part of the java.util.stream.Collectors class, is used to apply a mapping function to the elements of a stream before collecting them. This method is useful when you need to transform the elements of a stream and then collect the transformed elements.
The joining() method in Java, part of the java.util.stream.Collectors class, is used to concatenate the elements of a stream into a single String. This method is useful when you need to create a single string from a collection of elements, with or without delimiters.
The groupingByConcurrent() method in Java, part of the java.util.stream.Collectors class, is used to group elements of a stream concurrently by a classifier function. This method is useful when you need to organize elements into groups based on a common attribute and perform the grouping operation in a parallel or concurrent manner.
The groupingBy() method in Java, part of the java.util.stream.Collectors class, is used to group elements of a stream by a classifier function. This method is useful when you need to organize elements into groups based on a common attribute.
The flatMapping() method in Java, part of the java.util.stream.Collectors class, is used to flatten a stream of collections before collecting the elements. This method is useful when you have a stream of collections and want to collect the individual elements of those collections.
The filtering() method in Java, part of the java.util.stream.Collectors class, is used to filter elements of a stream before collecting them. This method is useful when you need to apply a filter condition and then collect the filtered elements.
The collectingAndThen() method in Java, part of the java.util.stream.Collectors class, is used to perform a collection operation and then apply a finishing transformation to the result. This method is useful when you need to modify the result of a collection operation before using it.
The averagingInt() method in Java, part of the java.util.stream.Collectors class, is used to calculate the average of integer values obtained from processing a stream of objects. This method is useful when you need to determine the average of certain properties of the elements in a stream.
The counting() method in Java, part of the java.util.stream.Collectors class, is used to count the number of elements in a stream. This method is useful when you need to determine the size of a stream after applying certain operations.
The search(Object o) method in Java, part of the java.util.Stack class, is used to search for an object in the stack and return its 1-based position from the top of the stack. This method is useful for finding the position of an element within the stack.
The push(E item) method in Java, part of the java.util.Stack class, is used to push an item onto the top of the stack. This method is fundamental to the stack’s LIFO (Last-In-First-Out) behavior.
The pop() method in Java, part of the java.util.Stack class, is used to remove the element at the top of the stack and return that element. This method is fundamental to the stack’s LIFO (Last-In-First-Out) behavior.
The peek() method in Java, part of the java.util.Stack class, is used to view the element at the top of the stack without removing it. This method is useful when you need to inspect the top element without modifying the stack.
The empty() method in Java, part of the java.util.Stack class, is used to check whether a stack is empty. This method is useful for determining if there are any elements left in the stack.
The useDelimiter() method in Java, part of the java.util.Scanner class, is used to set a custom delimiter pattern for the Scanner. This method is useful when you need to parse input data with delimiters other than the default whitespace.
