To figure out how inner interface works, we can compare it with nested classes. Nested classes can be considered as a regular method declared in outer class. Since a method can be declared as static or non-static, similarly nested classes can be static and non-static. Static class is like...
JavaScript's double not operatoris basically double use of (!) operator. This is alogical not operator. (!!) operator converts non-Boolean to Boolean. As you know,!operator reverses the logic, i.e., it returnfalsefor!truevalue andtruefor!false. Examples of (!) Operator !false Output: ...
Static in Java is a keyword that can be used with variables, methods, blocks, and nested classes. When the static keyword is used in Java, it signifies that a particular member belongs to a type itself, rather than to an instance of that type. This al
In this tutorial, let us discuss what is the opposite of preventDefault() method in JavaScript? Submitted by Pratishtha Saxena, on July 24, 2022 Before discussing the opposite of preventDefault(), first, let us know what is this method?
Closures are a powerful feature in JavaScript where a function has access to its own scope, access to the outer function’s scope, and access to global variables. They are particularly useful for maintaining state in asynchronous operations and creating data privacy. ...
The serializability of a class is enabled by the class implementing thejava.io.Serializableinterface. Classes that do not implement this interface will not have any of their state serialized or deserialized. Fields should be private to prevent outer classes from modifying those fields easily. Instead...

When the object data is not visible to the outer world, it creates data abstraction. If needed, access to the Objects’ data is provided through some methods. We don’t need to provide details about all the functions of an object. When we hide the internal implementation of the different ...
Can I use LEN or DATALENGTH in a WHERE clause? Can I use OUTER JOIN on 2 columns at the same time? Can row_number() work in UNION STATEMENTS ? Can someone explain just exactly why xp_cmdshell is such a massive risk?! Can SQL Profiler give you the Missing Index information? Can Sy...
We have an outer class namedStaticFunctionUsageclass that holds the other inner class in the below class.InnerClasshas a static function. And another inner class namedInnerClass1has a non-static method. Now, moving on to themainmethod, it is seen that the static function is directly accessibl...
