The first two questions have no answers because they are exactly the assignment. I suppose I have to use loops.

The code does that for some inputs but not for others.

I tried to print...

1 - take out upper cases and spaces from string input
2 - string should be written along the rows of a caesar square
3 - case decryp it should be written top to bottom left to right
4-case...

I thought I had answered it. Sorry I wasn't clear. Maybe I didn't get it as well.
Here are the instructions:

Write a Java program to encrypt a string of text using a Caesar Square: the string...

Yes, I am. What you said would be encrypt. This examples are given in the assignment:

Sample Input/Output
Case A
Input:
java CaesarBox -encrypt abcd
Logic:
a b
c d
Output:

It should put the string character by character in a ceaser box from top to bottom left to right, so if the input is abcd the caesar box should be:

a c
b d

And then it should decrypt the...

What could be wrong now?

--- Update ---

No, sorry

Sorry, the input is abcd

But I have to put it into a caesar box before encrypt/decrypt

decrypt should put it into a caesar box like

a c
b d

Fixed:

The method Encrypt should for example
input:
ab
cd

output:acbd

the method decrypt should take same input and output:abcd

what could be wrong:
