Java String.replace not working

Question

This is my code.

String x = "1+&radic;10";
x = x.replace(".*", "x");
System.out.println(x);

This should return "x" but istead it is returning "1+√10". Why isn't this working?

String#replace doesn't support regex, use String#replaceAll:

x = x.replaceAll(".+", "x");

See updated answer, you need .+ instead of .* since .* matches twice once for empty string and once for full string.
