Tell if string contains a-z chars [duplicate]

Answer 1

You can use regular expressions

// to emulate contains, [a-z] will fail on more than one character, 
// so you must add .* on both sides.
if (s.matches(".*[a-z].*")) { 
    // Do something
}

this will check if the string contains at least one character a-z

to check if all characters are a-z use:

if ( ! s.matches(".*[^a-z].*") ) { 
    // Do something
}
