This example demonstrate about How can I intercept the Status Bar Notifications in AndroidStep 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 src/MyListener.javapublic interface MyListener { void setValue (String packageName) ; }Step 3 − Add the following code to src/MyListener.javapackage app.tutorialspoint.com.notifyme ; import android.content.Context ; import android.service.notification.NotificationListenerService ; import android.service.notification.StatusBarNotification ; import android.util.Log ; public class NotificationService extends NotificationListenerService { private String TAG = this .getClass().getSimpleName() ; Context context ; static MyListener ...

In C, we can use the freopen() function for redirection purposes. Using this function, we can redirect existing FILE pointer to another stream. The syntax of the freopen is like below:FILE *freopen(const char* filename, const char* mode, FILE *stream)In C++ also, we can do the redirection. In C++, the streams are used. Here we can use our own stream, and also redirect system streams. In C++, there are three types of streams.istream : Stream, that can support input onlyostream : Stream, that can support output onlyiostream : These can be used for input and output.These classes, and file stream classes ...

At first, let us first create a slider in Java −JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 40); slider.setMinorTickSpacing(10); slider.setMajorTickSpacing(20); slider.setPaintTicks(true); slider.setPaintLabels(true);Now, we will snap closest tick mark value as shown below −slider.setSnapToTicks(true);The following is an example to create a JSlider that snap to the closest tick mark −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Frame with Slider"); JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 40); slider.setMinorTickSpacing(10); ...

Use the concept of initializeUnorderedBulkOp(). Let us first create a collection with documents −>db.upDateMultipleRowsDemo.insertOne({"CustomerName":"John", "CustomerPurchaseAmount":500}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6ceb06d78f205348bc626") } >db.upDateMultipleRowsDemo.insertOne({"CustomerName":"Chris", "CustomerPurchaseAmount":700}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6ceb26d78f205348bc627") } >db.upDateMultipleRowsDemo.insertOne({"CustomerName":"David", "CustomerPurchaseAmount":50}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6ceb36d78f205348bc628") } >db.upDateMultipleRowsDemo.insertOne({"CustomerName":"Larry", "CustomerPurchaseAmount":1900}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6ceb46d78f205348bc629") }Following is the query to display all documents from a collection with the help of find() method −> db.upDateMultipleRowsDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd6ceb06d78f205348bc626"), "CustomerName" : "John", "CustomerPurchaseAmount" : 500 } { ...

The HTML DOM Anchor pathname property is used to set or return the path name of the href attribute.Following is the syntax to set the pathname property −anchorObj.pathname = pathAbove, path is the pathname of the URL.Following is the syntax to return the pathname property −anchorObj.pathnameLet us now see an example to implement the DOM Anchor pathname property −Example Live Demo Company Products Display pathname Display hreflang function display1() { var a = document.getElementById("mylink").pathname; document.getElementById("myid").innerHTML = a; } ...

The HTML DOM Link disabled property sets/returns whether element is enabled or disabled.SyntaxFollowing is the syntax −Returning boolean value - true/falselinkObject.disabledSetting disabled to booleanValuelinkObject.disabled = booleanValueBoolean ValuesHere, “booleanValue” can be the following −booleanValueDetailstrueIt defines that the is disabled.falseIt defines that the is not disabled and it is also the default value.ExampleLet us see an example for Link disabled property − Live Demo Link Disabled Link-disabled Sales Target Week: var divDisplay = document.getElementById("divDisplay"); var inputWeek = document.getElementById("WeekSelect"); var extStyle = document.getElementById("extStyle"); divDisplay.textContent ...

In C++11, the lambda was introduced. Lambdas are basically a part of, that can be nested inside other function call statements. By combining lambda expressions with the auto keyword, they can be used later.In C++14, these lambda expressions are improved. Here we can get the generalized or generic lambda. For example, if we want to create a lambda, that can add integers, add numbers, also concatenate strings, then we have to use this generalized lambda.Syntax of the lambda expression is looking like this −[](auto x, auto y) { return x + y; }Let us see one example to get the ...

In C++, we have different containers like vector, list, set, map etc. To iterate through these containers, we can use the iterators. We should be careful when we are using iterators in C++. When we are using iterating over a container, then sometimes, it may be invalidated. If the shape, size is changed, then we can face this kind of problems. In the following example, we can identify the problem of invalidation.Example Code#include #include using namespace std; int main() { vector vec{11, 55, 110, 155, 220}; for (auto it=vec.begin(); it!=vec.end(); it++) if ...

To set different height for multiple rows, use the setRowHeight() method for separate rows for which you want to increase the row height. Let us first see an example to create a table with same height for all the rows −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo { public static void main(String[] argv) throws Exception { DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel); tableModel.addColumn("Language/ Technology"); tableModel.addColumn("Text Tutorial"); tableModel.addColumn("Video Tutorial"); ...
