Working with Methods Can anyone help?

[RanLineR]

Activity3 working with methods

Sample

Enter an integer value: -9
Enter and integer value: 2
Enter a double value: 3.8
Enter first string : Anna
Enter second string : anna

The Absolute value of -9 is 9
The square root of 9 is 3.0
9 raise to 2 is equivalent to 81.0
The floor value of 3.58 is 3.0
The ceil value of 3.58 is 4.0
Anna is Equivalent to anna

this sample output needs to be the same with my work.


Sample:

int x =-9
result = Math.abs(x);

system.out.println("the absolute value of" +x+" is " +result);


this is what hint they give me.
i dont really understand what will i do in order to get the method.
:(



import java.io.*;
public class Activity4{
public static void main (String args[])throws IOException{

BufferedReader br = new BufferedReader(
new InputStreamReader(System.in));

what next?? thanks~!

and somebody said that i can work easier using JOption?

[Eranga]

No of course you can with JOption.

But you've to deals with correct conversions, JOption returns an object of string.

[Eranga]

Did you try anything with JOption, show it here if so?

[RanLineR]

they said JOption is much easier to use, could you give me some sample?

[Eranga]

String ans = JOptionPane.showInputDialog("Enter an integer value:");
int iVal = Integer.parseInt(ans);

Try to understand above.

they said JOption is much easier to use, could you give me some sample?

A Scanner is even easier to use. Read the API documentation.

kind regards,

sir can you do the the absolute value of" +x+" is " +result); ?

[Tolls]

Please don't ask people to do your homework for you.

[RanLineR]

im just asking how to use that code because im new to it.

[Eranga]

Please don't ask people to do your homework for you.

Agreed. I've already give a hint with the code, and I asked OP to try to understand it. Seems it wont that way.

[Eranga]

im just asking how to use that code because im new to it.

Do you have an idea about the code segment I've post earlier?

[RanLineR]

okay thanks by the way.much appreciated =)

[RanLineR]

yep a little. as i said im a begginer.

[Eranga]

If you don't want to learn from what we say, I'm sure it's not encourage us to helping you out.

[Eranga]

yep a little. as i said im a begginer.

little means that you don't have fully understand something. Why don't you try to clarify those things first of all. Keep in mind lol, that's the way to learn. You must explore the world, and get the experience your self. ;)

[RanLineR]

what do you mean sir?

[RanLineR]

yes sir =))))

[Eranga]

You ask a question here, and we all comment on you. Actually I gave you a simple code segments, and I ask you to try to understand it. Why I'm said that is, without experimenting something ourselves we can't learn a lot. Experience make a big difference. :)

What you've done is without doing that you ask another question. That's not good.

[RanLineR]

Tolls said that i dont ask anymore. Thats why i stop.
