### method:append(java.lang.CharSequence,int,int) [CHANGED]
### append public StringBuilder append (CharSequence s, int start, int end) Description copied from interface: `Appendable` Appends a subsequence of the specified `characterCharSequence` to this sequence. Characters of the argument `s`, starting at index `start`, are appended, in order, to the contents of this sequence up to the (exclusive) index `end`. The length of this `Appendable`. An invocationsequence is increased by the value of `end - start` . Let n be the length of this methodcharacter sequence just prior to execution of the `formout.append(csq,` method. Then the character at index k in this character sequence becomes equal to the character at index k in this sequence, if k is less than n; otherwise, it is equal to the character at index k+start, end) when `csq`-n in the argument `s`. If `s` is `notnull` , behaves in exactlythen this method appends characters as if the same way ass parameter was a sequence containing the invocation
         out.append(csq.subSequence(start, end))
four characters `"null"`. Specified by: `append` in interface `Appendable` Parameters: `s` - The characterthe sequence from which a subsequence will be appended. If `csq` is `null`, then characters will be appended as if `csq` contained the four characters `"null"`to append. `start` - Thethe starting index of the first character inthe subsequence to be appended. `end` - Thethe end index of the character following the last character inthe subsequence to be appended. Returns: Aa reference to this `Appendable` object. Throws: `IndexOutOfBoundsException` - Ifif `start` or `end` areis negative, or `start` is greater than `end` ,or `end` is greater than `csqs.length()`
### append public StringBuilder append (CharSequence s, int start, int end) Description copied from interface: `Appendable` Appends a subsequence of the specified character sequence to this `Appendable`. An invocation of this method of the form `out.append(csq, start, end)` when `csq` is not `null`, behaves in exactly the same way as the invocation
         out.append(csq.subSequence(start, end))
Specified by: `append` in interface `Appendable` Parameters: `s` - The character sequence from which a subsequence will be appended. If `csq` is `null`, then characters will be appended as if `csq` contained the four characters `"null"`. `start` - The index of the first character in the subsequence `end` - The index of the character following the last character in the subsequence Returns: A reference to this `Appendable` Throws: `IndexOutOfBoundsException` - If `start` or `end` are negative, `start` is greater than `end`, or `end` is greater than `csq.length()` | ### append public StringBuilder append (CharSequence s, int start, int end) Appends a subsequence of the specified `CharSequence` to this sequence. Characters of the argument `s`, starting at index `start`, are appended, in order, to the contents of this sequence up to the (exclusive) index `end`. The length of this sequence is increased by the value of `end - start` . Let n be the length of this character sequence just prior to execution of the `append` method. Then the character at index k in this character sequence becomes equal to the character at index k in this sequence, if k is less than n; otherwise, it is equal to the character at index k+start-n in the argument `s`. If `s` is `null`, then this method appends characters as if the s parameter was a sequence containing the four characters `"null"`. Specified by: `append` in interface `Appendable` Parameters: `s` - the sequence to append. `start` - the starting index of the subsequence to be appended. `end` - the end index of the subsequence to be appended. Returns: a reference to this object. Throws: `IndexOutOfBoundsException` - if `start` is negative, or `start` is greater than `end` or `end` is greater than `s.length()`

### method:append(char) [CHANGED]
### append public StringBuilder append (char c) Description copied from interface: `Appendable` Appends the string representation of the `char` argument to this sequence. The argument is appended to the contents of this sequence. The length of this sequence increases by `1`. The overall effect is exactly as if the argument were converted to a string by the specifiedmethod `String.valueOf(char)`, and the character in that string were then `appended` to this `Appendable` character sequence. Specified by: `append` in interface `Appendable` Parameters: `c` - The character to appenda `char`. Returns: Aa reference to this `Appendable` object.
### append public StringBuilder append (char c) Description copied from interface: `Appendable` Appends the specified character to this `Appendable`. Specified by: `append` in interface `Appendable` Parameters: `c` - The character to append Returns: A reference to this `Appendable` | ### append public StringBuilder append (char c) Appends the string representation of the `char` argument to this sequence. The argument is appended to the contents of this sequence. The length of this sequence increases by `1`. The overall effect is exactly as if the argument were converted to a string by the method `String.valueOf(char)`, and the character in that string were then `appended` to this character sequence. Specified by: `append` in interface `Appendable` Parameters: `c` - a `char`. Returns: a reference to this object.

### method:toString() [CHANGED]
### toString public String toString() Description copied from interface: `CharSequence` Returns a string containingrepresenting the charactersdata in this sequence in. A new `String` object is allocated and initialized to contain the same order ascharacter sequence currently represented by this object. This `String` is then returned. Subsequent changes to this sequence . The lengthdo not affect the contents of the `string will be the length of this sequenceString` . Specified by: `toString` in interface `CharSequence` Returns: a string consistingrepresentation of exactlythis sequence of characters.
### toString public String toString() Description copied from interface: `CharSequence` Returns a string containing the characters in this sequence in the same order as this sequence. The length of the string will be the length of this sequence. Specified by: `toString` in interface `CharSequence` Returns: a string consisting of exactly this sequence of characters | ### toString public String toString() Returns a string representing the data in this sequence. A new `String` object is allocated and initialized to contain the character sequence currently represented by this object. This `String` is then returned. Subsequent changes to this sequence do not affect the contents of the `String`. Specified by: `toString` in interface `CharSequence` Returns: a string representation of this sequence of characters.
