Valid @SuppressWarnings Warning Names in Java

Java's @SuppressWarnings annotation allows programmers to suppress compiler warnings for specific code segments. The warnings to be suppressed are specified within parentheses after the annotation, but what exactly can be written there?

IDE-Dependent Warnings

The list of valid @SuppressWarnings warning names depends on the IDE or compiler you are using. Eclipse Galileo, for example, supports the following warnings:

• all (suppresses all warnings)
• boxing (warnings related to boxing/unboxing)
• cast (warnings related to cast operations)
• dep-ann (warnings related to deprecated annotations)
• deprecation (warnings related to deprecation)
• fallthrough (warnings related to missing breaks in switch statements)
• finally (warnings related to finally blocks that don't return)
• hiding (warnings related to locals that hide variables)
• incomplete-switch (warnings related to missing entries in switch statements)
• nls (warnings related to non-nls string literals)
• null (warnings related to null analysis)
• restriction (warnings related to usage of discouraged or forbidden references)
• serial (warnings related to missing serialVersionUID field for a serializable class)
• static-access (warnings related to incorrect static access)
• synthetic-access (warnings related to unoptimized access from inner classes)
• unchecked (warnings related to unchecked operations)
• unqualified-field-access (warnings related to field access unqualified)
• unused (warnings related to unused code)

Additional Warnings

Subsequent versions of Eclipse and other IDEs/compilers add additional valid warning names. For instance, Indigo adds "javadoc," "rawtypes," "static-method," and "super," while Juno adds "resource" and "sync-override."

Other Compilers

While the warnings listed above are common in many Java environments, other compilers may have their own unique set of valid warning names. It is important to consult the documentation for your specific IDE or compiler to determine the exact list of supported warnings.
