Now let us see a program of Intel 8085 Microprocessor. This program will find the LCM of two8-bit numbers.Problem StatementWrite 8085 Assembly language program to find LCM of two 8-bit numbers stored at location8000H and 8001HDiscussionIn this program we are reading the data from 8000H and 8001H. By loading the number, we are storing it at C register, and clear the B register. The second number is loaded into Accumulator. Set DE as the 2's complement of BCregister. This DE is used to subtract BC from HL pair.The method is like this:let us say the numbers are 25 and 15. ... Read More
Before getting into an example, we should know what is a countdown timer in android. Count down timer as simple as we see in watches and mobile phones. we can set count down time after completion of time it will stop and get 0 values.There are four methods are available to use countdown timer as shown below -onTick(long millisUntilFinished ) - In this method we have to pass countdown mill seconds after done countdown it will stop Ticking.onFinish() - After finish ticking, if you want to call any methods or callbacks we can do in onFinish().start() - It is used ...

Before getting into the example, We should know that, What is asyncTask. AsyncTask is going to do operations/actions in background thread and update on mainthread. Here is the simple solution about Android AsyncTask Parallel Execution.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 declare two imageviews and one button, When user click on button it going to download two images from different ... Read More
While walking near any lake or forest around the sea, you might have seen a different and unique feature of some trees, whose roots are not under but above the ground. They are known as Mangrove trees and they have aerial roots.Now, the reason why have roots above the land is that they are the underground root type which needs and demands more oxygen. Under the ground, the soil is not able to support or provide enough oxygen to the roots and therefore this root system outgrows aerial roots which grow vertically up to the fresh air above the soil.Read More
Set a BigInteger object.BigInteger one;Now, create a ByteArray −byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);For Decimal, we have used toString() method without any parameter value.String strResult = one.toString();The following is an example −Example Live Demoimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one; // ByteArray byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr); // Decimal String strResult = one.toString(); System.out.println("ByteArray to Decimal = "+strResult); } }OutputByteArray to Decimal = 65536
Use the subset() method to get elements from a limit. At first, create NavigableSet and add elements −NavigableSet set = new TreeSet(); set.add(10); set.add(25); set.add(40); set.add(55); set.add(70); set.add(85);Now, use the subset() method −set.subSet(40, 85)The following is an example to implement subset() method of Java NaviagbleSet class −Example Live Demoimport java.util.NavigableSet; import java.util.TreeSet; public class Demo { public static void main(String[] args) { NavigableSet set = new TreeSet(); set.add(10); set.add(25); set.add(40); set.add(55); set.add(70); set.add(85); set.add(100); System.out.println("Returned Value = " + set.subSet(40, 85)); } }OutputReturned Value = [40, 55, 70]
The status register is of length 8-bits wide. The processor can only read but not write and it is only selected when CS* is 0, A3-0 is 1000, and IOR* is 0.About the present state of 8257 the information about the status is provided. The five blocks are important others are marked 0 since they are not in use.UD1 = Update in progress0 = Update not in progressTCn1 = TC reached for Channel n (n = 0–3)0 = TC not yet reached for Channel nFig: Interpretation of the contents of the status registerThe read operation of the status register is ...

Now let us see a program of Intel 8085 Microprocessor. This program will find the multiplication result of two BCD numbers.Problem StatementWrite 8085 Assembly language program to find two BCD number multiplication. The numbers are stored at location 8000H and 8001H.DiscussionIn this program the data are taken from 8000H and 8001H. The result is stored at location 8050H and 8051H. As we know that 8085 has no multiply instruction so we have to use repetitive addition method. In this process after each addition we are adjusting the accumulator value to get decimal equivalent. When carry is present, we are incrementing the ... Read More
In android using implicit intent, we can send data with other applications using ACTION_SEND action. We have to call Intent.createChooser() to open default chooser of android mobile to send the data. it may same or different in Android mobiles.This example demonstrates how to share app data with other applications 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, it contains textview, when user clicks on text view ... Read More
The name of the parent directory of the file or directory can be obtained using the method java.io.File.getParent(). This method returns the parent directory pathname string or null if there is no parent named.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static void main(String[] args) { File file = new File("C:" + File.separator + "JavaProgram" + File.separator, "demo1.txt"); System.out.println("File: " + file); System.out.println("Parent: " + file.getParent()); } }The output of the above program is as follows −OutputFile: C:\JavaProgram\demo1.txt Parent: C:\JavaProgramNow ...
