Using the “==” operator for comparing text values is one of the most common mistakes Java beginners make. This is incorrect because“==”only checks the referential equality of twoStrings,meaning if they reference the same object or not. Let’s see an example of this behavior: String str...
The abortOnError attribute is set to true by default, meaning that any anomaly in the query string will abort the page request. Under each <page> node, there is a list of nodes-one for each supported query-string parameter. In the sample code, a parameter can be defined using...

“Two String values (or two Character values) are considered equal if their extended grapheme clusters are canonically equivalent. Extended grapheme clusters are canonically equivalent if they have the same linguistic meaning and appearance, even if they are composed from different Unicode scalars behind...
Crucially, this comparison is case-sensitive, meaning it considers uppercase and lowercase letters as distinct. In this example, since “Swift” and “swift” differ in case, the condition inside the if statement evaluates to false, and the program prints “The strings are not equal.”. ...
