Search char and insert new char after that char from string without loop

Question

I want to search a particular char from string without any loop and then i want to insert new char after that.

String a = "my%name%is%";

I want to find "%" and then i want to insert "?" char.

Output result:

a = "my%?name%?is%?";

You can't do this reasonably without looping. Any other function you could use to do this will most likely loop internally. — jotik

Use replace(char a,char b).

void replaceString(){
   String a = "my%name%is%";
   System.out.printlnt(a.replace("%","%?"));
}

You can also use replaceAll(String regex, String replacement)

String a = "my%name%is%";
System.out.println(a.replaceAll("([.*^%])", "%?"));//prints my%?name%?is%?
