### Question:
StringUtils { public static String stripLeadingDigits(String str) { for (int i = 0; i < str.length(); i++) { if (!Character.isDigit(str.charAt(i))) { return str.substring(i); } } return ""; }  static String stripLeadingDigits(String str); static boolean isValidDNSSuffix(String suffix); static String[] getStrings(String str); static Collection<String> getStringCollection(String str); static Collection<String> getTrimmedStringCollection(String str); static String[] getTrimmedStrings(String str); static String arrayToString(String[] strs); static final String[] EMPTY_STRING_ARRAY; }### Answer:
@Test public void testStripLeadingDigits() { Assert.assertEquals("", StringUtils.stripLeadingDigits("1234567890")); Assert.assertEquals("abc", StringUtils.stripLeadingDigits("1234567890abc")); }
