I need help ASAP, I am only allowed to use for loops and a detailed guide would be nice!

Worksheet #3: The Caesar Cipher CSC 142 Computer Programming I Due Wednesday 1/25/2017 Background BCE, was a Roman general and politician. Julius Caesar, who lived from 100 BCE to 44 who played a key role in the downfall of the Roman Republic and the rise of the Roman Empire. As a politician, he was the champion of lower class citizens and the working man. As a general, he was dominant, and is considered one of the greatest military commanders in history. After conquering territory, Caesar returned to Rome and used his army and his popularity to instigate a civil war and take He was eventually assassinated by a group of Roman and his assassination led to a power vacuum that transformed Rome from a republic to an empire. Caesar's military and political activities meant secret codes and ciphers were important for him. However, ciphers A B and codes were uncommon and encoding methods were primitive. Caesar encoded messages by shifting e letter forward or backward a certain number of spaces, and the private or secret key was how many letters to shift. For NAAQ example, if the key were 3, Awould become D, B would become E, C would become F, and so on Imagine two disks, with each letter of the alphabet printed in order on the outside of the disk, with a smaller di sk laid on top of a larger disk. By lining up the letters on the two rings then shifting one disk forward by a certain number of places the Caesar shift cipher is easy to apply. You will be performing this shift using software Assignment You will be implementing a Caesar cipher in Java. You will do this by implementing two methods -one method to encrypt (turn a plain text into a cipher text and one to decrypt (turn a cipher text into a plain text). These methods will need to take a parameter that is the private key The principal operation to implement the Caesar cipher is shifting each character by a certain amount. The same operation will work for both encryption and decryption. Hint: explore the char primitive data type and the Character wrapper class. Questions You will use your program to encrypt 3 plain texts and to decrypt 3 cipher texts To encrypt a plain text, you take each letter, and shift it forward a certain number of letters. That number is your secret key. You will be given the secret key and asked to encrypt the message using that key To decrypt a cipher text, you take each letter, and shift it backward a certain number of letters. That number is the secret key. You will not know the secret key. Think about how you can guess the correct key
