Java regex match not working -

i trying match string using java regex, match failing. may issue in code below?

string line = "copy of 001";  boolean b = pattern.matches("001", line);  system.out.println("value : "+b);

output value

value : false

matches match whole string. use matcher , find() method instead:

boolean b = pattern.compile("001").matcher(line).find();

or make pattern more flexible , allow have prefixing "001". example:

".*001"

for simple, though, pattern overkill , simple indexof job more efficiently:

boolean b = line.indexof("001") > -1;
