     Parameters:

     Return Value :

     -Syntax:public static String copyValueOf(char[] ch)Parameters:ch : The character array.Return Value : This function returns the string with the contents of character array copied -

     // Java code to demonstrate the working of  // copyValueOf implementation 1  public class Copy1 {   public static void main(String args[]) {             // Initialising Character array      char[] ch = {'A', 's', 't', 'h', 'a', ' ', 'T', 'y', 'a', 'g', 'i'};             // Initialising String      String ch2 = "";             // Copying value in ch2      // now ch2 is equal to "Astha Tyagi"      ch2 = ch2.copyValueOf( ch );             // Printing String      System.out.println("The new copied string is : " + ch2);   } } -

     Output:

     -The new copied string is : Astha Tyagi-

     In the second implementation, the subarray can also be extracted instead of whole array. Implementation 2 :

     Syntax:

     public static String copyValueOf(char[] ch, int index, int num)

     Parameters:

     Top Answer

     Answered Sep 02, 2011 · 7 votes

     String myString="A155B45C77D89";String[] parts = myString.split("(?<=\\d)(?=\\p{Alpha})");System.out.println(Arrays.toString(parts));-

     Output:

     [A155, B45, C77, D89]

     Explanation:

     String.split works with regular expressions. The regular expression (?<=\d)(?=\p{Alpha}) says "match all substrings preceeded by a digit, succeeeded by a alphabetic character.

     In a string such as "A155B45C77D89", this expression is matched by the empty substrings
