What's the quickest way to compare a string with a character for equality. I have a string and I want to see if it contains a newline, carriage return or space character.

Thanks

try using the indexOf method of String:

if s.indexOf("\n") returns a -1, then it
doesn't contain a newline,

the same should work with carriage return and space:
s.indexOf("\r")
s.indexOf(" ")
0

String data = "your string";
boolean contains_cr = (data.indexOf('\r') >= 0);
boolean contains_new_line = (data.indexOf("\r\n") >= 0);
boolean contains_space = (data.indexOf(' ') >= 0);
0
