The loop you are using is not actually a valid foreach. The foreach construct is used for iterating over a Collection or array.

Here is one example to print each char in a String:

public void hello( String st)
    {
        for(char c : st.toCharArray())
        {
            System.out.println(c);
        }    
    }
