Question

Are generic, cast, and threadsafe reserved keywords in java?
I am aware of the 52 keywords in java but looking for the new reserved keyword list.

Answer 1

See this link here. It’s the reserved keyword list for Java 6.

    abstract    continue  for           new            switch
    assert (c)  default   goto (a)      package        synchronized
    boolean     do        if            private        this
    break       double    implements    protected      throw
    byte        else      import        public         throws
    case        enum (d)  instanceof    return         transient
    catch       extends   int           short          try
    char        final     interface     static         void
    class       finally   long          strictfp (b)   volatile
    const (a)   float     native        super          while

    (a) not used
    (b) added in 1.2
    (c) added in 1.4
    (d) added in 5.0 

So, no, neither of those three words you listed are in the reserved set.

This keyword list can also be found in the Java language specification in section 3.9.
