Strings
We looked at the charAt, indexOf, lastIndexOf, toUpperCase, and toLowerCase methods.
Let's look at a few more:
substring( int startPos, int endPos ) – return the String that
consists of the characters in the original String from startPos to endPos – 1.
The new String does NOT contain the character at endPos. An easy way to
remember this: the length of the new String is the difference between endPos and
startPos.
substring( int startPos ) – return the substring of the original String
starting at startPos and continuing to the end of the original String.
trim() – return a new String which has whitespace trimmed off the ends of the
original String. This doesn't remove all whitespace from a String – only at the ends.
Let's try some examples:
Print a String in reverse order
Print the location of every 'C' in a DNAsequence
