Java Utililty Methods String Split by Line

String[] fastSplit(final String line, final char c)
Splits a string using a character.

int nextSplit = line.indexOf(c);
if (nextSplit < 0) {
 return new String[] { line };
final List<String> splits = new ArrayList<String>();
int lastSplit = -1;
while (nextSplit > 0) {
 splits.add(line.substring(lastSplit + 1, nextSplit));
...

String[] split(String aLine, char delimiter, char beginQuoteChar, char endQuoteChar, boolean retainQuotes, boolean trimTokens)
Splits the specified delimited String into tokens, supporting quoted tokens so that quoted strings themselves won't be tokenized.

String line = clean(aLine);
if (line == null) {
 return null;
List<String> tokens = new ArrayList<String>();
StringBuilder sb = new StringBuilder();
boolean inQuotes = false;
for (int i = 0; i < line.length(); i++) {
...

return split(line, DEFAULT_DELIMITER_CHAR);

String[] split(String line)
This method splits a single CSV line into junks of String .

List<String> results = new ArrayList<>();
StringBuffer buffer = new StringBuffer(line);
while (buffer.length() > 0) {
 if (buffer.indexOf("\"") == 0) {
 int endIndex = buffer.indexOf("\"", 1);
 String result = buffer.substring(1, endIndex);
 results.add(result);
 buffer.delete(0, endIndex + 2);

 tokens.add(line.substring(prevPos, index));
 prevPos = index + 1;
