The WordNet is a part of Python's Natural Language Toolkit. It is a large word database of English Nouns, Adjectives, Adverbs and Verbs. These are grouped into some set of cognitive synonyms, which are called synsets. To use the Wordnet, at first we have to install the NLTK module, then download the WordNet package. $ sudo pip3 install nltk $ python3 >>> import nltk >>>nltk.download('wordnet') In the wordnet, there are some groups of words, whose meaning are same. In the first example, we will see how wordnet returns meaning and other details of a word. Sometimes, if some ... Read More
Spinner is just like a drop down button, using this button we can select a item from set of items. This example demonstrate about how to add items to a spinner 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. Step 3 − Add the following code to src/MainActivity.java.import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.MotionEvent; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.Spinner; import android.widget.Toast; import java.util.ArrayList; public class MainActivity ...

A literal is a source code representation of a fixed value. They are represented directly in the code without any computation. Literals can be assigned to any primitive type variable. For example. byte a = 68; char a = 'A'; byte, int, long, and short can be expressed in decimal(base 10), hexadecimal(base 16) or octal(base 8) number systems as well. Prefix 0 is used to indicate octal, and prefix 0x indicates hexadecimal when using these number systems for literals. For example − int decimal = 100; int octal = 0144; int hexa = 0x64; String ...

Before getting into types of intent, we should know what is an intent?. Intent is to perform an action. It is mostly used to start activity, send broadcast receiver, start services and send message between two activities. There are two intents available in android as Implicit Intents and Explicit Intents.Explicit Intent − It going to connect the internal world of an application such as start activity or send data between two activities. To start new activity we have to create Intent object and pass source activity and destination activity as shown below −Intent send = new Intent(MainActivity.this, SecondActivity.class); startActivity(send);And we ...

In spite of the fact that 8085 is an 8-bit microprocessor, but there are some instructions are there available in the 8085 instruction set which can do 16-bit additions also. As the 8085 internal architecture is only 8-bits, this instruction easily takes double the time needed to add two 8-bit numbers. Here, DAD is a mnemonic, which stands for Double ADd and also rp stands for any one of the following register pairs as mentioned below. rp = BC, DE, or HL As rp can have any of the three values, there are three opcodes for this type ...

Mutational testing in C# includes verifying the quality of a test suite in the active solution. For this, use a tool called “VisualMutant”. It sets as an extension to the Visual Studio IDE. The following are the capabilities of a testing tool. The following are the features of VisualMutant, which is a mutation test tool − View modified code fragments in C#. Run NUnit and XUnit tests on generated mutants View details about any mutant right after the start of the mutation testing process It gives results as mutation score. Measure the quality of the test suite. To create ... Read More
In different programming languages, First Class objects are those objects, which can be handled uniformly. First Class objects can be stored as Data Structures, as some parameters of some other functions, as control structures etc. We can say that a function in Python is First Class Function, if it supports all of the properties of a First Class object. What are the properties of First Class Functions? It is an instance of an Object type Functions can be stored as variable Pass First Class Function as argument of some other functions Return Functions from other function Store Functions in ...

In 8085 Instruction set, ANA is a mnemonic, which stands for “ANd Accumulator” and “R” stands for any one of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M This instruction is used to AND contents of R with Accumulator’s content. The result thus produced for this AND operation will be stored back in to the Accumulator over writing its previous content. As R can have any of the eight values, there are eight opcodes for this type of instruction. It occupies only 1-Byte in ... Read More
In 8085 Instruction set, ANI is a mnemonic, which stands for “ANd Immediate with Accumulator” and “d8” stands for any 8-bit or 1-Bytedata. This instruction is used to AND 8-bit immediate data with the Accumulator’s content. The result of this ANDingoperation will be stored in the Accumulator itself over writing its previous content. As it is an arithmetic operation do S, P, and Z flags are affected based on the result. Cy is reset to 0, and AC is set to 1. It occupies 2-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ANI Data E6 ... Read More
In 8085 Instruction set, ORA is a mnemonic, which stands for “OR Accumulator” and “R” stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M This instruction is used to OR contents of R with the Accumulator. The result of OR operation will be stored back in the Accumulator. As R can have any of the eight values, there are eight opcodes for this type of instruction. It occupies only 1-Byte in memory. Mnemonics, Operand Opcode(in HEX) Bytes ... Read More
