Run 1
The code is highly readable. It has a clear, single-purpose structure as a custom exception class. Nesting is non-existent, with a flat class hierarchy and straightforward constructors. Each constructor's intent is unambiguous, following standard Java exception patterns. The code is concise, avoiding unnecessary boilerplate while providing all standard constructor variants. Each action (constructor call) is on its own line, maintaining clean separation. The reading flow is natural: class declaration, serialVersionUID, then constructors in a logical order. The Javadoc comments, while repetitive, are clear and consistent with the codebase style. The only minor drawback is the repetitive 'Creates a new instance' documentation, which adds little value and could be more descriptive, but this does not significantly impact readability.

The code is highly readable. It follows a clear, standard structure for a custom exception class, extending CodecException with no complex logic. Nesting is completely flat. The intent is unambiguous: it defines an EncoderException with four standard constructors. Code length is concise and appropriate for the functionality. Each constructor is a single action on its own line, maintaining clean action granularity. Reading flow is natural, with each constructor grouped logically and documented succinctly. The only minor issue is the repetitive Javadoc comments ('Creates a new instance.'), which could be more descriptive, but this is a negligible readability concern.

This code is highly readable. It follows a clear and logical structure: package declaration, imports, Javadoc, class declaration, serialVersionUID, and four constructors in a sensible order. Nesting is essentially flat, with no conditional or loop complexity. Intent is obvious—it's a specialized exception for encoder failures. Code length is minimal and appropriately concise for an exception class. Each constructor is a single action, delegating to the parent class, maintaining one action per line. Reading flow is natural, as constructors are ordered intuitively (empty, message+cause, message, cause). Javadoc is present, albeit repetitive, which slightly reduces polish but aids clarity. Overall, this is an exemplary model of clean, maintainable code.
Run 1
Code Structure: Logically organized, with the serialization field followed by constructor overloads. Nesting: Minimal, limited to the class and constructor bodies. Clarity of intent: The class name, inheritance, and class documentation clearly identify an encoder-specific exception. Code length: Concise and appropriate for a standard exception class, though repeated constructor comments add little value. Action granularity: Each nonempty constructor performs one superclass call on its own line. Reading flow: Consistent formatting and straightforward delegation make the code easy to follow.
Run 2
Code Structure: The class is logically organized, with its serialization field followed by constructor overloads. Nesting: Minimal nesting makes the code easy to scan. Clarity of intent: The class name, inheritance, and class-level documentation clearly identify an encoder-specific exception. Code length: The implementation is concise, although repeated constructor comments add little information. Action granularity: Each constructor performs at most one action, with superclass calls on separate lines. Reading flow: Consistent formatting and conventional Java structure provide a natural reading flow.
Run 3
Code Structure: A logically organized exception class with a serialization identifier followed by constructors. Nesting: Minimal, limited to class and constructor scopes. Clarity of intent: The class name, inheritance, and class documentation clearly identify an encoder-specific exception; constructor documentation is generic rather than informative. Code length: Concise implementation, though repeated constructor comments add minor verbosity. Action granularity: Each nonempty constructor performs a single superclass call on its own line. Reading flow: Consistent formatting and straightforward constructor overloads make the code easy to scan and understand.
