Replace all √num from a string java

Question

I have a string that contains String q = "What's the value of √32 and √83?";, my problem is replacing √num with sqrt(32) and sqrt(83).

That means my string should output : -

What's the value of sqrt(32) and sqrt(83)

is it possible?

Are you trying to replace it programatically? like find every sqrt symble and replace it with `sqrt()`? — Luke, Oct 16 '20 at 06:27

Use a regex replacement on the pattern √(\d+)\b, and replace with sqrt(...):

String q = "What's the value of √32 and √83?";
String output = q.replaceAll("√(\\d+)\\b", "sqrt($1)");
System.out.println(output);

This prints:

What's the value of sqrt(32) and sqrt(83)?
