public static String removeLeadingZeroes(String value):

给定有效的非空输入,该方法应返回所有前导零被删除的输入.因此,如果输入是"0003605",则该方法应返回"3605".作为特殊情况,当输入仅包含零(例如"000"或"0000000")时,该方法应返回"0"

public class NumberSystemService {
/**
 * 
 * Precondition: value is purely numeric
 * @param value
 * @return the value with leading zeroes removed.
 * Should return "0" for input being "" or containing all zeroes
 */
public static String removeLeadingZeroes(String value) {
     while (value.indexOf("0")==0)
         value = value.substring(1);
          return value;
}

我不知道如何为字符串"0000"编写代码.
