How can the absence of whitespace negatively affect Java code?

The absence of whitespace in Java code can indeed lead to ambiguous code structure. Whitespace plays an important role in improving the readability of code, even though Java is not whitespace-sensitive in terms of syntax, unlike languages such as Python. When whitespace is not used appropriately, it can make the code more difficult to read and understand, which increases the likelihood of misinterpretation by other developers or even the original author when revisiting the code.

For instance, without adequate spacing or line breaks, it can be challenging to distinguish between different blocks of code, such as loops, conditionals, or method definitions. This obscurity could lead someone to misunderstand the logic or flow of the code, potentially leading to errors in maintenance or further development. Enhanced readability through proper use of whitespace contributes to clearer communication of intent in code structure, helping prevent logical errors that stem from ambiguity in the program's layout.

The other options presented do not accurately capture the implications of missing whitespace in Java. Syntax errors related to data types typically stem from incorrect coding rather than whitespace. Java code will execute on the JVM regardless of whitespace usage, and the creation of Java bytecode is not hindered by whitespace either; it may simply make the bytecode harder to interpret by humans,
