The hashtable collection in C# is a non-generic collection of items represented as key-value pairs. Each key is a unique, non-null element. The value on the other hand can be duplicated and/or null. The Hashtable class in C# represents the hashtable collection. This class provides the relevant methods to create objects, alter items in the collection, etc. The hashtable collection can be expressed as an array or ArrayList in C#. In this article, let’s discuss how we can convert a hashtable collection into an array. How to Convert Hashtable into an Array? To convert the hashtable into an array, the ... Read More

As per the problem statement we need to find all the Emails present in the file. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose there is given paragraph and it contains many different email ids and we want to extract all the mail id present in that paragraph. For e.g. − “I am a boy with email boy54@gmail.com. My friend’s email is friend78@gmail.com.”.” From the above paragraph, we need to take out the given two mail id in the paragraph i.e., boy54@gmail.com and friend78@gmail.com.  Instance-2 ...

In this article, we will compare two different text files which are saved in our system. We will check line by line of each text file, by comparing those we can identify the similarities and differences. Let’s see how we can do it by using the Java programming language. To Show You Some Instances Instance-1 Below figure depict two different text files with same content and hence output will be two files with same content. Instance-2 Below represents two files, say file1.txt and file2.txt with their content. file1.txt This is amazing. Java Language. file2.txt This is amazing. Python ... Read More

As per the problem statement, we need to find the first and last word of the given String. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose there is String “Java is a well-known high-level, class-based object-oriented programming language that Sun Microsystems created and first distributed in 1995. Over 3 billion devices run Java, which is currently owned by Oracle” After printing the first and last word of this String i.e “Java” and “Oracle”. Instance-2 Suppose there is String “For the creation of their desktop, web, ... Read More

In TypeScript, ‘null’ refers to the data type or value. The null is a keyword in TypeScript, which we can use to represent the absent or empty value. So, we can use ‘null’ to define the variable's data-type or initialize the variable. In this tutorial, we will learn the different use cases of the null value and data type in TypeScript. Syntax Users can follow the syntax below to use the null keyword as a data type or value. let null_var: null = null; In the above syntax, ‘null’ refers to the data type of the null_var named ...

If you have worked with other programming languages, such as Python, you have heard about lambda functions. The arrow function is similar to the lambda function, which provides a shorter way to define the function inside TypeScript. We can create the function without a ‘function’ keyword by using the fat arrow and storing it inside the variable. After that, we can use that variable to invoke the function whenever required. Also, the arrow function doesn’t have any identity, as it is anonymous. So, we can identify it using the variable in which we have stored it. Syntax Users ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to separate odd and even elements into two separate arrays and print the result. A number is said to be an even number if it is divisible by 2, else the number is an odd number. Note − The array must be an integer array. In this article, you will see how to separate even and odd numbers of an array into two different arrays by using Java programming language. Let’s start. To Show ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to increment all negative numbers by 1 and decrement all positive numbers by 1. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {12, 21, -31, -14, 56, 16, 17, -18, 9} After updating the array element are: -30 -17 -13 8 11 15 16 20 55 (sorted) Instance-2 Suppose the original array is {19, ...

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to delete or eliminate the odd numbers present in the array and print the even array. Note − The array must be an integer array. A number is said to be an odd number if the array is not divisible by 2. In this article, you will see how to remove odd numbers from an array by using Java programming language. Let’s explore. To Show You Some Instances Instance-1 Suppose the original array is ... Read More
