Java coding conventions and guidelines

My favorite sources for Java coding conventions and guidelines:

• Code Conventions for the Java Programming Language (Sun, now Oracle)
• Java Coding Standard (NASA / Jet Propulsion Laboratory, Caltech)
• Secure Coding Standard for Java (CERT / Oracle)
• Book: Effective Java, 2nd ed. (Josh Bloch, Sun / now Google)
• Book: Clean Code (Robert C. Martin aka “Uncle Bob”)
