There is no function called indexOf in the class StringBuffer

I suggest you use String instead of StringBuffer .And when you append you use the operator '+' .For example :
Code:
String name="Tom";
name+="AAA";
name+="aaa";


now the content of name is "TomAAAaaa"

I tried this code...
Code:
public static void main(String[] args) {
StringBuffer mybuff=new StringBuffer("Mohamed Sami");
mybuff.append(" ddd");
System.out.print(mybuff.indexOf("ddd"));


}


and the output is 13.... :grin:
