### Class Structure

- **Utility classes**: `abstract` class + `protected` constructor
- **Constants classes**: Same pattern

### Argument Validation

Use `AssertionUtil` at method entry:
- `AssertionUtil.assertArgumentNotNull("argName", value)`
- `AssertionUtil.assertArgumentNotEmpty("argName", value)`

### Exception Handling

- Wrap checked exceptions in runtime exceptions from `org.codelibs.core.exception`

### Core Design Principles
CoreLib follows a **utility-class pattern** where most functionality is exposed through static methods:

- **Assertion-based validation** - All methods validate inputs using `AssertionUtil.assertArgumentNotNull()` and `AssertionUtil.assertArgumentNotEmpty()`
- **Exception wrapping** - Checked exceptions are consistently wrapped in runtime exceptions (e.g., `ClassNotFoundException` → `ClassNotFoundRuntimeException`)
