Question

What would be a simple implementation of a method to convert a String like ‘Hello there everyone’ to ‘helloThereEveryone’. In JavaME support for String and StringBuffer utility operations are quite limited.

Answer 1

Quick primitive implementation. I have no idea of restrictions of J2ME, so I hope it fits or it gives some ideas…

String str = 'Hello, there, everyone?';  StringBuffer result = new StringBuffer(str.length()); String strl = str.toLowerCase(); boolean bMustCapitalize = false; for (int i = 0; i < strl.length(); i++) {   char c = strl.charAt(i);   if (c >= 'a' && c <= 'z')   {     if (bMustCapitalize)     {       result.append(strl.substring(i, i+1).toUpperCase());       bMustCapitalize = false;     }     else     {       result.append(c);     }   }   else   {     bMustCapitalize = true;   } } System.out.println(result); 

You can replace the convoluted uppercase append with:

result.append((char) (c - 0x20)); 

although it might seem more hackish.
