How to create ripple animation in my Android App?
Before getting into the code, we should know what is ripple animation in android. Ripple animation is just like wave momentum. In android it is appears on view like Textview, Button, etc using background attribute.This example demonstrate about how to integrate ripple animation to 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 added a button with back ground as ripple.Step 3 − Create a file ...
Read MorePre & post increment operator behavior in C, C++, Java, and C#
The Pre increment and post increment both operators are used as increment operations. The pre increment operator is used to increment the value of some variable before using it in an expression. In the pre increment the value is incremented at first, then used inside the expression.if the expression is a = ++b; and b is holding 5 at first, then a will hold 6. Because increase b by 1, then set the value of a with it.Example Code#include using namespace std; main () { int a, b = 15; a = ++b; cout
Read MoreIn Android how to register a custom Intent filter to a broadcast receiver?
Before getting into the example, we should know what is intent filter in android. An intent filter is an instance of the IntentFilter class. Intent filters are helpful while using implicit intents, It is not going to handle in java code, we have to set it up in AndroidManifest.xml. Android must know what kind of intent it is launching so intent filters give the information to android about intent and actions.Before launching intent, android going to test action test, category test and data test. This example demonstrate about how to use custom intent filters to a broadcast receiver in android.Step ...
Read MoreCan we store CSS color values in MySQL?
Yes, we can. In order to store CSS color value, you can use CHAR(6) without # symbol for hexadecimal. Let us see an example and create a tablemysql> create table storeCSSColorDemo -> ( -> CSSValue char(6) -> ); Query OK, 0 rows affected (0.53 sec)Insert some records in the table using insert command. The records here are individual color values in hexadecimal, for which we have used char(6)mysql> insert into storeCSSColorDemo values('FF0000'); Query OK, 1 row affected (0.13 sec) mysql> insert into storeCSSColorDemo values('FFA500'); Query OK, 1 row affected (0.86 sec) ...
Read More8086 program to add two 16 bit BCD numbers with carry
In this program we will see how to add two 16-bit BCD numbers with carry.Problem StatementWrite 8086 Assembly language program to add two 16-bit BCD numbers stored in memory offset 500H – 501H and 502H – 503H.DiscussionHere we are adding the 16-bit data byte by byte. At first we are adding lower byte and perform the DAA instruction, then Add higher bytes with carry, and again DAA to adjust. The final result is stored at location offset 600H, and if carry is present, it will be stored at 601H.We are taking two numbers 8523 + 7496 = 16019InputAddressData……50023501855029650374…… Flow Diagram Program OutputAddressData……600196016060201……

This example describes how to use the HttpSession object to find out the creation time and the last-accessed time for a session. We would associate a new session with the request if one does not already exist. Session Tracking Session Tracking Session info Value ...
Read MoreWhat is an application Object in JSP?
The application object is direct wrapper around the ServletContext object for the generated Servlet and in reality an instance of a javax.servlet.ServletContext object.This object is a representation of the JSP page through its entire lifecycle. This object is created when the JSP page is initialized and will be removed when the JSP page is removed by the jspDestroy() method.By adding an attribute to application, you can ensure that all JSP files that make up your web application have access to it.
Read MoreReset the primary key to 1 after deleting all the data in MySQL?
To reset the primary key to 1 after deleting the data, use the following syntaxalter table yourTableName AUTO_INCREMENT=1; truncate table yourTableName;After doing the above two steps, you will get the primary key beginning from 1.To understand the above concept, let us create a table. The query to create a table is as followsmysql> create table resettingPrimaryKeyDemo -> ( -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY -> ); Query OK, 0 rows affected (0.66 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into resettingPrimaryKeyDemo values(); Query OK, 1 row ...
Read MoreC++ Program that will fill whole memory
In this article we will see how to fill the whole memory by writing a simple C++ program. Here the logic is very simple. We shall create new integer variables by using the dynamic memory allocation. If we create some variables again and again, it will fill the entire primary memory.In C++ to dynamically allocate a memory space we can use the new keyword.The basic syntax of the new operator is like below.pointer_var = new data_typeTo deallocate the memory space, we can use the delete keyword. The syntax isdelete pointer_varNote After running this program it may slow down the performance ...
Read More8086 program to subtract two 16-bit numbers with or without borrow
In this program we will see how to subtract two 16-bit numbers with and without borrow.Problem StatementWrite 8086 Assembly language program to subtract two 16-bit number stored in memory location 3000H – 3001H and 3002H – 3003H.Discussion8086 is 16-bit register. We can simply take the numbers from memory to AX and BX register, then subtract them using SUB instruction. When the Borrow is present, the CY flag will be 1, so we can store borrow into memory, otherwise only store AX into memory.InputAddressData……30002D3001FE3002AD3003BC…… Flow Diagram Program OutputAddressData……300480300541300600……
