How to print the properties in an object
I have the following method that is meant to print all the details in a hashmap (allStudents). this hashmap contains references to objects of different students.
what i need is to be able to print each object stored in allStudents, and each of those objects properties....
Please show me the light!!!
public void printAllStudents()
for (Integer eachStudent : allStudents) //for each loop
System.out.println(eachStudent);// prints out every element in set
}
Hi Kaj,
So when I overide the toString method, and then call
another method that prints out the contents of the
objects held a Map, the toString formatted text is
used? If so.. how does that work?For objects (as opposed to primitives), System.out.println() calls the toString method.

You really should throw away the code, go fetch some "How to learn basic Java with Wiggles The Bear" ebook and then start learning the basics instead of tripping on every single line of your code which is too complicated for you. -

Create a servlet which gets an InputStream of the file and writes it to the OutputStream of the response and call this servlet in `src` attribute. That's basically all.
Here's an example which covers the most of the minimum needs: [http://balusc.blogspot.com/2007/04/imageservlet.html]. -

IN THE TCODE SO10
NEW PAGE TERMS.
1) TERM MS AND CONDITONS TEXT.................................................
FIRST->NEXT, NEXT->NEXT,, TERMS--->TERMS.Hi,
1. Create a new page by Name : LAST
2. Identify the text element which will be the last element in the form in the debug mode.
Mostly Ex: SUM, TOTAL, LAST etc.,
3. the page linking should be
First --> Next
Next --> Next
4. In the Text element identified in the step 3.
Write the following code
/: NEW PAGE LAST
/: INCLUDE the standard text created for the terms and conditions in SO10
Check the syntax for the command but the logic will be the same.
It should resolve your problem. -

String a = "Hello";
How to print the address of a;How about the address a points to?Please try to answer the question in reply 1: why?
You can't get the address to which a variable points (except with JNI, but that again begs the question: why?) Also the address can change at any time as garbage collection moves objects around in memory. -

How to print the script in condensed mode
Hi to all,
Pls help me.
How to print the script in condensed mode and particular window only print in the condensed mode.Hi,
Hi
It will remove the blank spaces in front of the variable
and if you use the extension NO-GAPS
It will remove all the blank spaces in the variable field.
DATA: ws_val1 type char12.
ws_val1 = ' 100 123'.
Condense ws_val1.
Write / ws_val1.
Condense ws_val1 no-gaps.
write / ws_val1.
It will give output as
100 123
100123
The CONDENSE statement deletes redundant spaces from a string:
CONDENSE c NO-GAPS.
This statement removes any leading blanks in the field c and replaces other sequences of blanks by exactly one blank. The result is a left-justified sequence of words, each separated by one blank. If the addition NO-GAPS is specified, all blanks are removed.
Please check this link for sample code.
