is there a way to use tr/// (or equivalent) in java?

由 半城伤御伤魂 提交于 2019-11-26 22:00:41
问题 I would like to know if there is an equivalent to tr/// (as used in Perl) in Java. For example, if I wanted to replace all "s"s with "p"s in "mississippi" and vice versa, I could, in Perl, write #shebang and pragmas snipped... my $str = "mississippi"; $str =~ tr/sp/ps/; # $str = "mippippissi" print $str; The only way I can think of to do it in Java is to use a dummy character with the String.replace() method, i.e. String str = "mississippi"; str = str.replace('s', '#'); // # is just a dummy

When to use strtr vs str_replace?

I'm having a hard time understanding when strtr would be preferable to str_replace or vice versa. It seems that it's possible to achieve the exact same results using either function, although the order in which substrings are replaced is reversed. For example: echo strtr('test string', 'st', 'XY')."\n"; echo strtr('test string', array( 's' => 'X', 't' => 'Y', 'st' => 'Z' ))."\n"; echo str_replace(array('s', 't', 'st'), array('X', 'Y', 'Z'), 'test string')."\n"; echo str_replace(array('st', 't', 's'), array('Z', 'Y', 'X'), 'test string'); This outputs YeXY XYring YeZ Zring YeXY XYring YeZ Zring

PHP preg_replace/preg_match vs PHP str_replace

问题 Can anyone give me a quick summary of the differences please? To my mind they both do the same thing? Thanks 回答1: str_replace replaces a specific occurrence of a string, for instance "foo" will only match and replace that: "foo". preg_replace will do regular expression matching, for instance "/f.{2}/" will match and replace "foo", but also "fey", "fir", "fox", "f12", etc. [EDIT] See for yourself: $string = "foo fighters"; $str_replace = str_replace('foo','bar',$string); $preg_replace = preg
