For this tutorial, we’re going to usetwo existing Java librariesand compare their approaches to this problem. 2. The Problem Let’s consider the following requirement: we want to find the difference between the strings“ABCDELMN” and “ABCFGLMN”. Depending on what format we need the outpu...
If we want to calculate the difference between two date-times in a time-based (hour, minutes, or seconds) amount of time, we can use the Duration class: @Test public void givenTwoDateTimesInJava8_whenDifferentiating_thenWeGetSix() { LocalDateTime now = LocalDateTime.now(); LocalDateTime ...
In this guide, you will learndifference between ArrayList and LinkedList in Java.ArrayListandLinkedListboth implements List interface and their methods and results are almost identical. However there are few differences between them which make one better over another on case to case basis. ArrayList V...
Basically, they are just two different implementations of List interface.LinkedList is implemented with a double-linked list; ArrayList is implemented
Reference: http://beginnersbook.com/2013/12/difference-between-arraylist-and-vector-in-java/ JAVA COLLECTIONS ArrayListandVectorboth use Array as a data structure internally. However there are few differences in the way they store and process the data. In this post we will discuss the difference...
List and Set both are interfaces. They both extends Collection interface. In this post we are discussing the differences between List and Set interfaces in java. List Vs Set 1) List is an ordered collection it maintains the insertion order, which means u
Write a Java program to compute the difference between two dates (years, months, days). Sample Solution: Java Code: importjava.time.*;importjava.util.*;publicclassExercise1{publicstaticvoidmain(String[]args){LocalDatepdate=LocalDate.of(2012,01,01);LocalDatenow=LocalDate.now();Perioddiff=Per...

In this post, we will see how to calculate difference between two dates. Sometimes we have requirement to find no. of days between two dates or no. of hours between two dates. Java Program: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 ...
This post will discuss how to calculate differences between two lists x and y in Java. The solution should return all elements present in x that are not present in y.
