That behavior has purpose. Some default WordPress widgets use unordered lists, that’s why bullet points are disabled for unordered lists within widgets. You can try to enable bullet points for Text and SiteOrigin Editor widgets using the following CSS code. You can add CSS code to your ……………
Introduction Annotation is code about the code, that is metadata about the program itself. In other words, organized data about the code, embedded within the code itself. It can be parsed by the compiler, annotation processing tools and can also be made available at run-time too. First ……………

I ran below steps at mac machine. But steps will be almost similar for windows machine as well. Tools Require dex2jar JD-GUI Steps: Create a folder and copy apk (lets say abc.apk) to this folder. rename the extension (.apk) to zip. The the abc.apk is rename to ……………
Important facts about mipmap Android platform 4.3 and upward mipmap is by required to be added. There are many categories of mipmap drawables like mipmap-hdpi, mipmap-mdpi, mipmap-xhdpi etc. Mipmap is variety of drawables which is pe-processed, pre-calculated, pre-scaled, optimized, ready to use drawable. So that GPU (Graphics ……………
As the name suggests Custom Exception means it is Custom or User Defined Exceptions. User can create his/her own exceptions. For this, developer has to extend the existing checked or unchecked exception. Lets see some examples….. CustomUncheckedException.java package technical.jungle.com.exception; public class CustomUncheckedException extends NullPointerException{ CustomCheckedException(String s){ super(s); ……………
Let me give you some example to debug and track the flow. Program-1 ———–Illegal code package technical.jungle.com.exception; public class DemoArithmeticException { public static void main(String arfs[]) throws ArithmeticException { System.out.println(“www.TechnicalJungle.com”); System.out.println(“try”); int x = 0; int y = 10; int z = y / x; // ……………
Analysis on below program Class CheckedExceptionWorkerDeclare is trying to access the value which is not exist in the array. So exception handler will raise a flag for ArrayIndexOutOfBoundsException Throws is used to duck the exception back to calling method. Exception will be raised at line System.out.println(value[9]); So no further code will ……………
Exception handling works by transferring the execution of the program to an appropriate exception handler. For example, if you try to open a file to do some operation then situation aises like, File doesnot exist Some network problem No permission to open or read or write the ……………
All catch blocks must be ordered from most specific to most generic. There could be more than one “catch” block but “finally” clause will be at max one. ————————-Illegal code package technical.jungle.com.exception; public class ExceptionDemo { public static void main(String arfs[]) { int value[] = { 1, ……………
Let me give you small example to understand “Ducking” the exception. We know, methods are getting pushed to stack for execution. In the below picture: main() method is calling method1() method1() is calling method2() method2() is calling method3() Now imaging, A/An checked/unchecked exception occurred at method3(). That exception ……………
This is all about “how to implement” callback mechanism in Core Java with one interface and more callback methods. Steps to implement it Interface Class: One interface has to be created. This interface reference will be passed from UI class to background class. This will have two callback ……………
Exception Exception (or an exceptional event) which occurs when the program is in execution which can change the normal flow of the program. An Exception is the instance of java.lang. Exception is further classified into two parts: Checked Unchecked Checked Exception It will be checked at compile ……………

This is all about “how to implement” callback mechanism in Core Java with one interface. Steps to implement it Interface Class: One interface has to be created. This interface will be passed from UI class to background class. Background Operation Class: One class for doing background operation. Which will ……………
String class is immutable. Immutable means once String object created then any modification is not permitted in that object. So once created, can not be changed. Once String object is created then that object will be added in the String Literal Pool. If String object is created ……………
The ability to define behaviour that’s specific to a particular subclass type. It means a method is implemented in superclass and subclass has some specific behaviour so subclass is free to implement the same method again. This concept is called as overriding. Important Points Inheritance is required to achieve Overriding. Overriding is runtime polymorphism. ……………
Overloaded methods allows to reuse the same method name in a class, but having different signature. Signature means one method varies with other method in terms of below points: Number of arguments. Types of arguments. Order of arguments. There are some rules as below: Overloaded methods must ……………
Abstract class is the class which can hold fully implemented methods and unimplemented methods. That’s the major difference between Interface vs Abstract class. Have a look on below section 1.0, which demonstrate template for Abstract class.

Some key points for above demo: 1) Keyword “interface” used here for declaring it. 2) No method body. No curly braces like {…}. ……………
String For basic knowledge, you should read this. Its immutable. It means once object is created then that object can not be modified. Every immutable object is thread safe. Means same object can’t be shared by 2 or more threads at the same time. Object created as ……………
I observed whenever I am adding new widgets then that widget is shown in webview and its not be shown in mobile view. After some analysis I found the solution for that. So It’s possible to enable or disable Widgets (Gadgets) for mobile view.
Interface Click here for complete interface explanation. Can have only unimplemented methods. Supports multiple inheritance Can have only static and final variables. Methods can’t be static. Interface can’t hold main method or constructor. Interface can’t extend/implement abstract class. Keyword ‘interface’ is used to declare. Interface can extend other ……………
