How do I replace {a string inside Java

Anyone can help me replace 'in the string in Java{‘

For example

String str = "abc{ad}";
str = str.replace("{","(");

But this seems impossible

Solution

{and (are meteacharacters in Java. You should escape them with a backslash. Instead of using regular expressions, string.replace uses [string. Replaceall] [1] or string.replacefirst instead

str = str.replaceAll("\\{","\\(");
