The equality of two buffers can be checked using the method equals() in the class java.nio.IntBuffer. Two buffers are equal if they have the same type of elements, the same number of elements and same sequence of elements. The method equals() returns true if the buffers are equal and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { IntBuffer buffer1 = IntBuffer.allocate(n); buffer1.put(8); ...

In this program we will see how to transfer a block from one location to another location.Problem StatementWrite 8086 Assembly language program to transfer a block from one memory section to another memory section. The numbers are stored at memory offset 501 onwards. The block size is stored at memory offset 500.DiscussionHere we are initially setting up the source index register with the source of data blocks, then set the destination index register to store into another block. Then set the Data segment register and Extra Segment register to 0000H. By using MOVSB instruction, the entire block is transferred from ... Read More
This example demonstrates How to make a txt file and read txt file from internal storage in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken editext and button. When user click on button, it will take data from edittext and store in internal storage as /data/data//files/text/sample.txt. It going to append the data to textview from sample.txtStep 3 − Add the ... Read More
A custom tag is a user-defined JSP language element. When a JSP page containing a custom tag is translated into a servlet, the tag is converted to operations on an object called a tag handler. The Web container then invokes those operations when the JSP page's servlet is executed.JSP tag extensions let you create new tags that you can insert directly into a JavaServer Page. The JSP 2.0 specification introduced the Simple Tag Handlers for writing these custom tags.To write a custom tag, you can simply extend the SimpleTagSupport class and override the doTag() method, where you can place your ...

The fn:endsWith() function determines if an input string ends with a specified suffix.SyntaxThe fn:endsWith() function has the following syntax −boolean endsWith(java.lang.String, java.lang.String)ExampleFollowing example explains the functionality of the fn:substring function − Using JSTL Functions String ends with 123 String ends with TEST You will receive the following result −String ends with 123
To check whether the list is empty or not, use the isEmpty() method. TRUE is returned if the list is empty, else FALSE is the return value.The syntax is as followsboolean isEmpty()To work with CopyOnWriteArrayList class, you need to import the following packageimport java.util.concurrent.CopyOnWriteArrayList;The following is an example to implement CopyOnWriteArrayList class isEmpty() method in JavaExample Live Demoimport java.util.concurrent.CopyOnWriteArrayList; public class Demo { public static void main(String[] args) { CopyOnWriteArrayList arrList = new CopyOnWriteArrayList(); arrList.add(30); arrList.add(40); arrList.add(60); arrList.add(70); arrList.add(90); ...

An immutable copy of a duration where the required duration is added to it can be obtained using the plus() method in the Duration class in Java. This method requires two parameters i.e. the duration to be added and the TemporalUnit of the duration. Also, it returns the duration with the required duration added to it.A program that demonstrates this is given as follows −Example Live Demoimport java.time.Duration; import java.time.temporal.*; public class Demo { public static void main(String[] args) { Duration d = Duration.ofHours(10); System.out.println("The duration is: " + d); System.out.println("Duration ...

Use the add() method to insert elements in the Stream.Builder. The element to be added is a parameter for the add().The following is the syntax:default Stream.Builder add(T t)Here, t is the element to be added.Import the following package for the Stream.Builder class in Java:import java.util.stream.Stream;At first, create Stream.Builder:Stream.Builder builder = Stream.builder();Now, add elements using add() method:builder.add("This"); builder.add("is"); builder.add("it!");Here is an example displaying how to implement add() method of Stream.Builder in Java:Example Live Demoimport java.util.stream.Stream; public class Demo { public static void main(String[] args) { Stream.Builder builder = Stream.builder(); builder.add("This"); builder.add("is"); ...

In this section we will see how to count number of arguments in case of variable number of arguments in C.The C supports ellipsis. This is used to take variable number of arguments to a function. User can count the arguments by using one of the three different ways.By passing the first argument as count of the parametersBy passing last argument as NULL.Using the logic like printf() or scanf() where the first argument has the placeholders for other arguments.In the following program, we will total number of variable of arguments passed.Example Code#include #include int get_avg(int count, ...) { ...
