### Question:
SimpleString implements EnhancedString { @Override public CharSequence subSequence(int start, int end) { return value.subSequence(start, end); } SimpleString(String s); @Override SimpleString replaceText(Pattern p, String rText); @Override SimpleString patternToLower(Pattern p); @Override SimpleString patternToUpper(Pattern p); @Override int length(); @Override char charAt(int index); @Override CharSequence subSequence(int start, int end); @Override boolean equals(Object obj); @Override String getRaw(); @NotNull @Override String toString();  }### Answer:
@Test public void testSubSequence() { Assert.assertEquals(testSs.subSequence(4, 12), original.subSequence(4, 12)); }
