Convert string to camel case

Complete the method/function so that it converts dash/underscore delimited words into camel casing. The first word within the output should be capitalized only if the original word was capitalized.
e.g:

// returns "theStealthWarrior" toCamelCase("the-stealth-warrior")

// returns "TheStealthWarrior" toCamelCase("The_Stealth_Warrior")

最优解应该是用的正则，稍后再研究一下

public static String toCamelCase(String s){
    char[] c = s.toCharArray();
    String res = "";
    char flag = '-';
    if(s.length() == 0)
        return "";
    res += c[0];
    
    for(int i=1;i<c.length;i++) {
        if((c[i]=='-')||(c[i])=='_') {
            res += Character.toUpperCase(c[i+1]);
            i += 1;
            }
            else
                res += c[i];
            
        }       
    return res;
    }
