Kotlin Program to Read The Number From Standard Input
In this article, we will understand how to read a number from standard input in Kotlin. The ‘nextInt’ method is used to read the number. Below is a demonstration of the same Suppose our input is 45 The desired output would be The input value is 45 Algorithm Step 1 − Start Step 2 − Declare an integer: value Step 3 − Define the integer Step 4 − Read the values Step 5 − Display the value Step 6 − Stop Example 1 In this example, we will read the number from the standard input using ...
Read MoreKotlin Program to Swap Two Numbers
In this article, we will understand how to how to swap two numbers in Kotlin. This is done using a temporary variable. Below is a demonstration of the same Suppose our input is val1 : 45 val2 : 60 The desired output would be val1 : 60 val2 : 45 Algorithm Step 1 − Start Step 2 − Declare three integers: val1, val2 and tempVal Step 3 − Define the values Step 4 − Assign val1 to temporary variable Step 5 − Assign val2 to val1 Step 6 − Assign temporary tempVal variable to val2 Step 7 ...
Read MoreKotlin Program to Add two Numbers
In this article, we will understand how to add two numbers. This can be done using the ‘+’ operator. Below is a demonstration of the same Suppose our input is input1 : 10 input2 : 15 The desired output would be Sum : 25 Algorithm Step 1 − Start Step 2 − Declare three integers: val1, val2 and sum Step 3 − Define the integers Step 4 − Add the two values using an addition operator (+) Step 5 − Display the result Step 6 − Stop Example 1 In this example, we will add two numbers ...
Read MoreKotlin Program to Print an Integer
In this article, we will understand how to print an integer. Integer is a primitive data type that contains numbers up to 32 bits. Below is a demonstration of the same − Suppose our input is − 45 The desired output would be − The integer is: 45 Algorithm Step 1 − START Step 2 − Define the integer value in a variable Step 3 − Display it on the console Step 4 − STOP Example 1 In this example, we will simply print an integer using the print() method. First, declare an integer variable, which ...

In this article, we will understand how to print hello world in Kotlin. Hello world is stored as a string format and is printed using ‘print()’ function. Input Suppose our input is Hello World Output The expected out should be Hello World Algorithm Step 1 − START Step 2 − Define a string variable Step 3 − Display the string on the console Step 4 − STOP Example 1 In this example, we will simply display a string “Hello World” using the print() method in Kotlin − fun main() { val inputStr = ...
Read MoreWhat is execution engine in JAVA?
Execution Engine in Java is the core component of the JVM (java virtual machine) which communicates with different memory areas of the JVM. This component is used to execute the bytecode that is assigned to the runtime data areas via the classloader. In addition to this, each java Class file is executed through the execution engine, and each thread that is present in a running application is a distinct instance of the virtual machine’s execution engine. Hence, by reading this article, you will understand the execution engine in more detail, but before that, let’s comprehend what Java Virtual Machine is. ...
Read MoreCountDownLatch in Java
For a concurrent execution, CountDownLatch in Java is an important class that ensures one or more threads are in the queue for other threads to complete their set of operations. To better understand CountDownLatch in Java, in this article, you will learn the working of CountDownLatch with an example and methods of CountDownLatch. CountDownLatch in Java and its Working Process Based on the count value, the CountDownLatch is used for several purposes, which are as follows − When we begin the CountDownlatch with count value 1, it will simply work as an on/off latch or gate. On the other ...
Read MoreSeveral distinct caches for a single URL in HTML Cache?
Content caching is an effective way for fast and smooth user experience. Every URL in a web page can be linked to a single cache manifest section. However, there are certain large and rarely used files which decreases the overall speed of the Cache. Since they do not need to be changed but still gets re-downloaded every time the Cache gets updated, it is better to have such files in different cache with same URL. This will increase its speed and performance. So, how to spilt HTML cache? Before that, let’s understand what an HTML cache is. What is an ...

Read MoreHTML5 input type range for vertical orientation possible in Firefox?
In a thermometer, as the temperature increases, the mercury in it rises up too. Vice versa is the case for lowering the temperature. Similarly, if you want to create such effect on a webpage, it is done by the range type of input element in HTML5. This is known as range for vertical orientation. The most common use of the slider input is when we know the lower and higher margins. For instance, if we are developing a website that records the temperature of different places. You can have the temperatures as a sliding input range. It was possible to ...
