Why prefer char[] over String for password?

[Campbell Ritchie]

A few minutes ago, I wrote:. . .. If two String literals have the same contents . . . they are interned. . . .

But all String literals are interned. I was very imprecise there.

Have you read Corey McGlone's JavaRanch Journal article about “Strings, literally”? It might be old, but ut us still worth reading.
