  • There are three ways to compare string in java: By equals() method; By = = operator; By compareTo() method; 1) String compare by equals() method. The String equals() method compares the original content of the string. It compares values of string for equality. String class provides two methods: public boolean equals(Object another) compares this string to the specified object.
  • Convert a List<String> in a String with all the values of the List comma separated using Java 8 is really straightforward. Let's have a look on how to do that. Java 8 (or above) We simply can write String.join(..), pass a delimiter and an Iterable, then the new StringJoiner will do the rest:
  • Sep 22, 2016 · What is String in Java? In Java programming language, String is an object that contains sequence of characters in other words we can say String is a character array. But character array and Strings are quite different in Java, declarations, operations and usages are different. In Java programming language String is a built in class which can be ...
  • Jul 13, 2015 · Compare that to one line code of Java 8, where you get the stream from the list and used a Collector to group them. All you need to do is pass the grouping criterion to the collector and its done. This way, you can create multiple groups by just changing the grouping criterion.
  • split() is based on regex expression, a special attention is needed with some characters which have a special meaning in a regex expression. For example :
The Arrays.asList() method will convert an array to a fixed size List. To create a LinkedList, we just need to pass the List to the constructor of the java.util.LinkedList class. A java.util.ArrayList could be created in this way too. The Code. The following code example demonstrates converting an Array of Strings to a LinkedList of Strings.

When referring to early versions of Java I use phrases like "Java 1.0" or "Java 1.1," but after the fifth version of Java I use phrases like "Java 5" or "Java 8."
Nov 01, 2016 · Java 8 simplified the grouping of objects in the collection based one or more property values using groupingBy() method. The Collectors.groupingBy() method returns a Collector implementing a "group by" operation on input elements of type T, grouping elements according to a classification function, and returning the results in a Map.
In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions. However such languages may implement a subset of explicit string-specific functions as well. The Comparator.comparing method, introduced in Java 8, returns a Comparator object that will use the specified field as the sort key. The Comparator interface is a functional interface in Java 8, and the method implemented is the compare method. Therefore, the compare method is implemented by the comparing method using the specified key.
Java 8 comes with a range of built-in implementations of the Comparator interface. Consider the following Employee class: ...and the following list of employees: Here's how to build an object that implements the Comparator interface using the default comparing method of the Comparator object. The comparator compares the Employee objects based on their names: There's…Java 8 Comparator Sorting - Multiple Fields Example using Collections.sort () To sort on a single field then need to use the Comparator.comparing () method from Comparator class. Sorting based on multiple fields, you first have to create the two comparators using Comparator.comparing () method and next call Comparator.thenComparing () method.
