when using a array of strings in java, convert it to lowercase

java arrays string lowercase
Rdhao picture Rdhao · Dec 7, 2011 · Viewed 45.5k times · Source

I got a one dimensional array of strings in java, in which i want to change all strings to lowercase, to afterwards compare it to the original array so i can have the program check whether there are no uppercase chars in my strings/array.

i've tried using x.toLowercase but that only works on single strings. Is there a way for me to convert the whole string to lowercase?

Kind regards, Brand
