java的<tr>,有没有一种方法可以在Java中使用tr ///（或等效方法）？

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 character to make sure

// any original 's' doesn't get switched to a 'p'

// and back to an 's' with the next line of code

// str = "mi##i##ippi"

str = str.replace('p', 's'); // str = "mi##i##issi"

str = str.replace('#', 'p'); // str = "mippippissi"

System.out.println(str);

Is there a better way to do this?

Thanks in advance.

Commons' replaceChars may be your best bet. AFAIK there's no replacement (ar ar) in the JDK.
