用唯一替换替换字符串中的所有实例(Replace all instances in string with unique replacement)

 我试图用一个唯一的替换替换特定String的所有实例。 
 
 我想要的是什么： 
 
 如果我有这个字符串： 
 
String testScript = "while(true) { } while   (10 < 7) { } while((10 < 7)) { }";
 
 我想要这个输出： 
 
while(arg0 < 5000 && true) { } while(arg1 < 5000 && 10 < 7) { } while(arg2 < 5000 && (10 < 7)) { }
 
 我拥有的： 
 
 但是，传递给replaceAll的字符串不会再次被查询（现在很明显我想到了它）。 
 
while(arg0 < 5000 && true) { } while(arg0 < 5000 && 10 < 7) { } while(arg0 < 5000 && (10 < 7)){ }
 
 任何答案或评论，一如既往，非常感谢。 
 
 SSCCE： 
 
public static void main(String[] args) {
     int counter = 0;
     String testScript = "while(true) { } while   (10 < 7) { } while((10 < 7)) { }";
     String out = testScript.replaceAll("while\\s*\\(", "while(arg" + (counter++) + " < 5000 && ");
     System.out.println(out);
}

I'm attempting to replace all instances of a particular String with a unique replacement. 
 
What I would like:
 
If I have this String: 
 
String testScript = "while(true) { } while   (10 < 7) { } while((10 < 7)) { }";
 
I would like this output:
 
while(arg0 < 5000 && true) { } while(arg1 < 5000 && 10 < 7) { } while(arg2 < 5000 && (10 < 7)) { }
 
What I have:
 
However, the string passed in to replaceAll doesn't get queried again (obvious now I think about it).
 
while(arg0 < 5000 && true) { } while(arg0 < 5000 && 10 < 7) { } while(arg0 < 5000 && (10 < 7)){ }
 
Any answers or comments, as always, are greatly appreciated.
