I need to workout a way to test a string contains some words or not, doesn't matter uppercase or lowercase. E.g 

String ppe1 = "Mask"
String ppe2 = "mask"
String ppe3 = "MASK"

then when I do 

return ppe1.matches("[A-Za-z]*mask")  // it should return true

or

return ppe2.matches("[A-Za-z]*mask")  // it should return true

or

return ppe3.matches("[A-Za-z]*mask")  // it should return true

I know above regex is totally wrong,, but just wish to demo my idea for what I need, In a simple word, as long as string contains term 'Mask' , doesn't matter 'MASK' or 'mask' or 'mASk' or 'masK' or whatever combo, regex should detect the term and always return true. Please suggest with code example. Thanks

An arguably easier approach would be to force the case and then use contains:

return myString.toLowerCase().contains("mask");
