3. Nested If-else Statements Theif-elsestatements can be nested as well. The innerif-elsestatements will be executed based on the evaluation results of the outer conditional statements. In the following program, we are usingelse-ifstatement to add an additional conditional that will be evaluated...
Theswitchstatement allows us to replace several nestedif-elseconstructs and thus improve the readability of our code. Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java...

If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost ...
switch is expanded to any reference value. Also, case labels are no longer limited to constant values. It also helps replace if-else statement chains with switch, improving code readability. In this blog post, I’ll cover the changes introduced in the third preview of Pattern Matching for ...
Declare any class or interface public if it is specified as part of a published API, otherwise, declare it package-private. Similarly, declare class members and constructors (nested classes, methods, or fields) public or protected as appropriate, if they are also part of the API. Otherwise,...
