Functional Programming in Java, Second Edition: p.48 and following: "String.toUpperCase"

[dtonhofer]

In several places, the method

String.toUpperCase()

is misspelled as

String.toUppercase()

sometimes via the :: method reference,

String::toUppercase()

rather than

String::toUpperCase()

JavaDoc page:

String (Java SE 18 & JDK 18)
