Demo Code

public class Main 
{
   public static void main(String[] args)
   {//from   w  ww.j a va  2 s.c o  m
      char[] charArray = {'a', 'b', 'c', 'd', 'e', 'f'};
      boolean booleanValue = true;
      char characterValue = 'Z';
      int integerValue = 7;
      long longValue = 10000000001L; // L suffix indicates long
      float floatValue = 2.5f; // f indicates that 2.5 is a float
      double doubleValue = 133.333; // no suffix, double is default
      Object objectRef = "hello"; // assign string to an Object reference

      System.out.printf(
         "char array = %s\n", String.valueOf(charArray));
      System.out.printf("part of char array = %s\n", 
         String.valueOf(charArray, 3, 3));
      System.out.printf(
         "boolean = %s\n", String.valueOf(booleanValue));
      System.out.printf(
         "char = %s\n", String.valueOf(characterValue));
      System.out.printf("int = %s\n", String.valueOf(integerValue));
      System.out.printf("long = %s\n", String.valueOf(longValue)); 
      System.out.printf("float = %s\n", String.valueOf(floatValue)); 
      System.out.printf(
         "double = %s\n", String.valueOf(doubleValue)); 
      System.out.printf("Object = %s\n", String.valueOf(objectRef));
   }
