You could say microseconds is fast enough, but if you use it all over the place, it could add up to one or two milliseconds for ea.
However, reflection is comparitively slower - it may take a microsecond. Is there a reason in the second case beyond one of the compiler's features. Answer: Most statements like object creation or array creation happen in nanoseconds in Java. Regarding the first case with the while loop, the second case appears to be legal though it fails to compile. The method must be modified something like the following for its successful compilation. The following method however fails to compile.Ī compile-time error is issued indicating " missing return statement" even though the condition specified with the if statement is always true (it has a boolean constant that is never going to be changed neither by reflection). The method has an explicit return type which is with no return statement though it compiles fine.
#JAVA REFLECTION TO AVOID IF STATEMENTS CODE#
If not, the first set of code after the end of. The is a class that provides many methods that we can use to get metadata of the class and to. It is a process of examining or modifying the run time behavior of a class at run time. Java provides selections that let you choose actions with two or more alternative courses. The following method in Java compiles fine. If the Boolean expression evaluates to true then the block of code inside the if statement will be executed. Reflection in Java is an API (Application Programming Interface) that is used at runtime to analyze or change classes, methods, and interfaces. To avoid common errors and pitfalls in if statements (3.6). Compiler complains about “missing return statement” even though it is impossible to reach condition where return statement would be missing
