can any one please reply here i am getting same error like above and not using struts , <jsp:include using >

class MESSAGE_HEADER implements Serializable { long Reserved; long Logtime; char[] AlphaChar = new char[2]; short TransactionCode; short ErrorCode; char[] TimeStamp = new char[8]; char[] TimeStamp1 = new char[8]; char[] TimeStamp2 = new char[8]; short MEssageLength; MESSAGE_HEADER() { Reserved=10; } }

i want to convert above class to byte array and array size should be 40

please help me on how to convert class to byte array and size should be 40

please help me on how to convert class to byte array and size should be 40

If i try str = str1 + str2, then how many objects get created.

there are three objects ...... two already exists str1,str2 and new str

my doubt is that str =str + str2 ............ how many objects created

i think 3 objects are old : str , str2 and new : str
two object has reference and one object without reference
correct me if not

if i not specify any modifier will it give me a error

for this example can it possible that, not specifying any access modifier i.e. [default]

Thanks

correct answer given is: \s0[x][X][0-9a-fA-F]+\s

but what is the use of 0 at third position

Congratulations !! really Good Score

Henry

subclass has no access to superclass's static method. so, why there is restriction to define same method name as non-static
and if i define same method name with static in subclass it is compiling properly

Thanks for your help and i have one more doubt that

Hashcodes have nothing to do with there references

so what is the use of hashcode, if you can specify an example that better .

Thanks

Hi all,
I am preparing for SCJP 6 and i have one Question on String see the code below
public class ObjectMethods { public static void main(String[] args) { String str1 = new String("WhoAmI"); String str2 = new String("WhoAmI"); out.println("hash code for str1: " + str1.hashCode()); out.println("hash code for str2: " + str2.hashCode() + "\n"); out.println("str1.equals(str2): " + str1.equals(str2)); out.println("str1 == str2: "+ (str1==str2) + "\n"); } }

Output:
hash code for str1: -1704812257
hash code for str2: -1704812257

str1.equals(str2): true
str1 == str2: false

str1 and str2 are pointing to only one reference(same hashcode), so str1 == str2 should be true

Thank you all

congrats

Congrats

if it is on web page you can easily done by javaScript
