Effective Java Item 41: Overload String.valueOf(char[]) and String.valueOf(Object)

Overloading methods can hurt a lot...

 public class MyOverload {  
   public static void main(String[] args){  
     char[] a = new char[]{'a','b','c'};  
     System.out.println(String.valueOf(a));  
     Object o = new char[]{'a','b','c'};  
     System.out.println(String.valueOf(o));  
   }  
 }  

The result is

 abc
