The JsonObjectBuilder can be used for creating JsonObject models whereas the JsonArrayBuilder can be used for creating JsonArray models. The JsonObjectBuilder can be created using the Json class, it contains methods to create the builder object and build an empty JsonObject instance using the Json.createObjectBuilder().build(). The JsonArrayBuilder can be created using the Json class, it contains methods to create the builder object and build an empty JsonArray instance using Json.createArrayBuilder().build().Exampleimport java.io.*; import javax.json.*; public class JsonObjectTest {    public static void main(String[] args) {       JsonObject empObject = Json.createObjectBuilder().add("empName", "Jai")                                  .add("empAge", ...

We are going to write a program that calculates the following series in Python. Examine the example inputs and outputs for the program that we are going to write.Input: 34 3 + 33 + 333 + 3333 Output: 3702Input: 5 5 5 + 55 + 555 + 5555 + 55555 Output: 61725So, we will have two numbers, and we have to calculate the sum of the series generated as above. Follow the below steps to achieve the output.Algorithm1. Initialize the number let's say n and m. 2. Initialize a variable with the value n let's say change. 3. Intialize a ... Read More

In this tutorial, we are going to learn about the FuzzyWuzzy Python library. FuzzyBuzzy library is developed to compare to strings. We have other modules like regex, difflib to compare strings. But, FuzzyBuzzy is unique in its way. The methods from this library returns score out of 100 of how much the strings matched instead of true, false or string.To work with the FuzzyWuzzy library, we have to install the fuzzywuzzy and python- Levenshtein. Run the following commands to install them.pip install fuzzywuzzyIf you run the above command, you will the following success message.Collecting fuzzywuzzy Downloading https://files.pythonhosted.org/packages/d8/f1/5a267addb30ab7eaa1beab2 b9323073815da4551076554ecc890a3595ec9/fuzzywuzzy-0.17.0-py2.py3-none-any.whl Installing collected ...

In this tutorial, we are going to write a program which finds and prints anagrams using list and dictionary. We have different approaches to every problem. Try to write code without following the tutorial. If you are not able to generate any ideas to write logic, follow the below steps.Algorithm1. Initialize a list of strings. 2. Initialize an empty dictionary. 3. Iterate through the list of strings.    3.1. Sort the string and check if it is present in the dictionary as key or not.       3.1.1. If the sorted string is already present dictionary as a key ... Read More

In this tutorial, we are going to write a program to find out m multiples of a number n without using loops. For example, we have a number n = 4 and m = 3, the output should be 4, 8, 12. Three multiples of four. Here, the main constraint is not to use loops.We can use the range() function to get the desired output without loops. What is the work of the range() function? range() function returns a range object which we can convert into an iterator.Let's see the syntax of range().Syntaxrange(start, end, step)Algorithmstart - starting number to the ...

In this tutorial, we are going to write a program that counts the number of times a word occurs in the string. You are given the word and a string, we have to calculate the frequency of the word in the string.Suppose we have a string I am a programmer. I am a student. And the word is. The program that we are going to write will return a number 2 as the word occurs two times in the string.Let's follow the below steps to achieve our goal.Algorithm1. Initialize the string and the word as two variables. 2. Split the string ... Read More

In this tutorial, we are going to find the IP address of the client using the socket module in Python. Every laptop, mobile, tablet, etc.., have their unique IP address. We will find it by using the socket module. Let's see the steps to find out the IP address of a device.Algorithm Import the socket module. Get the hostname using the socket.gethostname() method and store it in a variable. Find the IP address by passing the hostname as an argument to the socket.gethostbyname() method and store it in a variable. Print the IP address. Let's write code for the above ... Read More

We have a list of strings and our goal is to sort the list based on the length of strings in the list. We have to arrange the strings in ascending order according to their lengths. We can do this using our algorithms or Python built-in method sort() or function sorted() along with a key.Let's take an example to see the output.Input: strings = ["hafeez", "aslan", "honey", "appi"] Output: ["appi", "aslan", "honey", "hafeez"]Let's write our program using sort(key) and sorted(key). Follow the below steps to achieve the desired output using a sorted(key) function.Algorithm1. Initialize the list of strings. 2. Sort ... Read More

In this tutorial, we are going to sort a list of tuples in increasing order by nth index key. For example, we have a list of tuples [(2, 2), (1, 2), (3, 1)] then, we have to sort it using 0th index element. The output for that list would be [(1, 2), (2, 2), (3, 1)].We can achieve this by using the sorted method. We have to pass a key while giving the list to the sorted function. Here, the key is the index on which the sorting is based.sorted takes a list and returns that list in ascending order ... Read More

We are given a string, and our goal is to reverse all the words which are present in the string. We can use the split method and reversed function to achieve the output. Let's see some sample test cases.Input: string = "I am a python programmer" Output: programmer python a am IInput: string = "tutorialspoint is a educational website" Output: website educational a is tutorialspointLet's follow the below steps to achieve our goal.Algorithm1. Initialize the string. 2. Split the string on space and store the resultant list in a variable called words. 3. Reverse the list words using reversed function. ... Read More
