The java.lang.StringBuilder.append(char[] str) method appends the string representation of the char array argument to this sequence.The characters of the array argument are appended, in order, to the contents of this sequence.The length of this sequence increases by the length of the argument. Step 4:Return or perform operation on character array. (2) substring Inserts a copy of a substring of str.The substring is the portion of str that begins at the character position subpos and spans sublen characters (or until the end of str, if either str is too short or if sublen is npos).

The Split method, as the name suggests, splits the String against the given regular expression. Description. Step 2: Create a character array of the same length as of string. Step 3: Traverse over the string to copy character at the i’th index of string to i’th index in the array. When compiler sees the statement: Step 1: Get the string. Insert Element in Array.
