A single element can be added to a LinkedList by using the java.util.LinkedList.add() method. This method has one parameter parameters i.e. the element that is to be inserted in the LinkedList.A program that demonstrates this is given as follows −Example Live Demoimport java.util.LinkedList; public class Demo { public static void main(String[] args) { LinkedList l = new LinkedList(); l.add("Magic"); System.out.println("The LinkedList is: " + l); } }OutputThe LinkedList is: [Magic]Now let us understand the above program.The LinkedList ...

As per DIP package Intel 8257 DMA controller chip is a 40-pin programmable Integrated Circuit. The pin diagrams of physical and functional are indicated below. The DMA controller chip 8257 works in two modes namely slave mode and master mode. Likely the processor also works in two modes namely active mode and HOLD mode. The processor normally works in active mode where the processor works as the master of the computer system. The processor goes to the HOLD state only when DMA transfer is required and it gives control to the system bus.When the processor is programming 8257 it is ... Read More
In this program we will see how to find the smallest number from a block of bytes using 8085.Problem StatementWrite 8085 Assembly language program to find the smallest number from a block of bytes.DiscussionIn this program the data are stored at location 8001H onwards. The 8000H is containing the size of the block. After executing this program, it will return the smallest number and store it at location 9000H.Logic is simple, we are taking the first number at register B to start the job. In each iteration we are getting the number from memory and storing it into register A. ... Read More
Before getting into example, we should know what is vertical Scroll View(Scroll View). Vertical Scroll view provide by android.widget.ScrollView class. It is used to scroll child views in a vertical direction.This example demonstrates how to use Vertical Scroll view.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. ...

This example demonstrate about How to reverse the direction of marquee of a Text View.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 text view and ellipsize property as marquee as shown below -android:ellipsize = "marquee" android:layoutDirection = "rtl" android:textDirection = "rtl" android:fadingEdge = "horizontal" android:marqueeRepeatLimit = "marquee_forever" android:scrollHorizontally = "true" android:singleLine = "true"Step 3 − Add the following code to src/MainActivity.javapackage com.example.andy.myapplication; import android.os.Bundle; ...

The method java.io.File.mkdirs() is used to create the specified directories, including the necessary parent directories. This method requires no parameters and it returns true on the success of the directories creation or false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static void main(String[] args) { String recursiveDirectories = "D:\a\b\c\d"; File file = new File(recursiveDirectories); boolean flag = file.mkdirs(); System.out.println("The directories are created recursively? " + flag); } }The output of the above program is as follows ... Read More
To work with SimpleDateFormat class in Java, import the following package.import java.text.SimpleDateFormat;To get the date, use the format() method as shown below. Firstly, set the date format −Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MM/yyyy");Now, we will get the date −simpleformat.format(cal.getTime())The following is the complete example −Example Live Demoimport java.text.SimpleDateFormat; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MM/yyyy"); System.out.println("Today's date = "+simpleformat.format(cal.getTime())); ...

A stack can be implemented using a LinkedList by managing the LinkedList as a stack. This is done by using a class Stack which contains some of the Stack methods such as push(), top(), pop() etc.A program that demonstrates this is given as follows −Example Live Demoimport java.util.LinkedList; class Stack { private LinkedList l = new LinkedList(); public void push(Object obj) { l.addFirst(obj); } public Object top() { return l.getFirst(); } public ...

In this program we will see how to find the HCF or GCD of two numbers using 8085.Problem StatementWrite 8085 Assembly language program to find the HCF of two numbers stored at memory location 8000H and 8001H.DiscussionThis problem is solved by the Euclidean algorithm to find HCF. This algorithm is very simple.The algorithm steps are as follows −If first number and second number are same, thengo to step 3.Else if first number < second number, then exchange no1 andno2.first-number A, then exchange B and AF00D90SUB B if B < A, subtract B from AF00EC3, 06, F0JMP LOOP Jump to LOOPF01148EXGMOV ...
