Examples of java.io.CharArrayWriter.toCharArray()

java.io.CharArrayWriter.toCharArray()
Answer the contents of the receiver as a char array. The array returned is a copy and any modifications made to this Writer after are not reflected in the result. @return char[] this CharArrayWriters contents as a new char array.
