Description

Demonstrates the length, charAt and getChars methods of the String class.

Demo Code

public class Main 
{
   public static void main(String[] args)
   {//from   w  w w . jav a 2 s  .  co  m
      String s1 = "hello there";
      char[] charArray = new char[5];

      System.out.printf("s1: %s", s1);

      // test length method
      System.out.printf("\nLength of s1: %d", s1.length());

      // loop through characters in s1 with charAt and display reversed
      System.out.printf("%nThe string reversed is: ");

      for (int count = s1.length() - 1; count >= 0; count--)
         System.out.printf("%c ", s1.charAt(count));

      // copy characters from string into charArray
      s1.getChars(0, 5, charArray, 0);
      System.out.printf("%nThe character array is: ");

      for (char character : charArray)
         System.out.print(character);

      System.out.println();
   } 
}
