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

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 find the array elements which are present in the odd position in an array and print them. A number is said to be even if it is divisible by 2 else it is called an odd number. Note − The array must be an integer array. 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 ... Read More

In Java, Array is a non-primitive data type which stores values of similar data type. As per the problem statement we have to detect which element is repeated maximum times in an array for maximum number of times and print its frequency. An array can contain duplicate values as well. So, the number of times an element is present in an array, that is called frequency of the element in the array. And the element whose frequency is more that is the most frequent element in the array. Let’s see how we can do it by using the Java programming ... 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 find the union of two arrays. Union refers to joining together whereas union of arrays refers to the new array combining all unique elements from the input arrays. 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 first array is {0, 3, 5, 6, 9, 1}. And the second array is {1, 2, 6, 10, 8, 7}. ... Read More
