Java BigDecimal class is used to deal with financial data. BigDecimal is preferred while dealing with high-precision arithmetic or situations that require more granular control over rounding off calculations. Java BigDecimal BigDecimals are Immutable, arbitrary-precision signed decimal numbers. Java BigDecimal class is defined in java.math package. Here is the BigDecimal class hierarchy: Java BigDecimal also […]

Java do while loop is used to execute a block of statements continuously until the given condition is true. do while loop in java is similar to while loop except that the condition is check after the statements are executed, so do while loop guarantees the loop execution at least once. Java do while loop […]

Java while loop is used to execute a block of statements continuously till the given condition is true. Earlier we looked into java for loop. Java while loop While loop in java syntax is as follows. while (expression) { // statements } The expression for while loop must return boolean value, otherwise it will throw […]

Java for loop is used to iterate over a range of values. We can use for loop to iterate over an array, a list, java set etc. Java for loop There are three types of for loop in java. General for loop for-each or enhanced for loop Java For loop with label Let’s look into […]

Every now and then we need to process items of a queue in a particular order. Priority queue is a Data Structure that does the job. Java priority queue is different from “normal” queue. Instead of “First-In-First-Out”, it retrieves the items in order of their priority. Priority Queue Java The java.util.PriorityQueue class, provides us an […]

Java Spliterator is one of the four iterators – Enumeration, Iterator, ListIterator and Spliterator. Java Spliterator Like Iterator and ListIterator, Spliterator is a Java Iterator, which is used to iterate elements one-by-one from a List implemented object. Some important points about Java Spliterator are: Java Spliterator is an interface in Java Collection API. Spliterator is […]

Java SortedMap is a Map that provides total ordering on its keys. Java SortedMap Java SortedMap can either be ordered according to the natural ordering of its keys or by providing a Comparator while creating map. If we don’t provide any Comparator (which should be able to accept key of the map) while creating SortedMap, […]

Java TreeSet is the most popular implementation of java.util.SortedSet. SortedSet is an interface that extends java.util.Set. Java Sorted Set provides total ordering on its elements. Java TreeSet In other words, while iterating the TreeSet, we can expect sorted data. Java TreeSet elements are ordered as per their natural ordering or we can provide a Comparator […]

Today we will look into Java Collections sort method. While working with Collections in java, more than often we need to sort the data. Java Collections sort() Java Collections class provides us with a very convenient method Collections.sort() to sort all List implementations such as LinkedList and ArrayList. There are two overloaded Collections.sort() methods, which […]
