String replace in java using regex

Question

I have String as:

"change(String.valueOf(data.get("abc")),data.get("xyz"),data.get("def"))"

I want to change it to:

change(String.valueOf(data.get("abc")),String.valueOf(data.get("xyz")),String.valueOf(data.get("def")))".

How can I do the above operation using Java regex?

Use : toString().replace("a", "o);

Example :

private String txt = "This is a text"

public static void main() String[arg] {

    String rplc = txt.replace("i", "o");
    System.out.print(rplc);

}

Output: Thos os a text

yourString.replaceAll("String.valueOf(data.get(").replaceAll("zzzzz").replaceAll("data.get(", "String.valueOf(data.get(").replaceAll("zzzzz", "String.valueOf(data.get(")

with 3 replaces

it is easer than using regex

According to your example, this simple replace should be enough:

result = source.replace(",data.get(\"");

For simple cases like this, you don't really need Regex (String.replaceAll(String regex, String replacement)) as using the regular replace is much faster (String.replace(CharSequence target, CharSequence replacement))
