Question

Replace # with \u0023 in a Java String which looks like below:

{subjectCategory:”s123″, subjectId:”111222333″, content:”test #comment999″, ownerId:”111″, ownerName:”tester”}

String.replace("#","\\u0023");

I’ve tried the above function, but it doesn’t seem to work.

Answer 1

You need to escape the backslash with another backslash:

string = string.replace("#", "\\u0023");

Test:

String s = "hello # world";
s = s.replace("#","\\u0023");
System.out.println(s); // prints hello \u0023 world
