Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

Question

1. Write the method named shift3()
You are given a String str. Return a new String where
all of the characters are "shifted" by 3. Here is the
algorithm to do this
1. Visit each character in the String
2. Create a new char by adding 3
3. Store the new character in the output string
Examples:
shift3("hello") returns "khoor"
shift3("cat") returns "fdw"
shift3("frog") returns "iurj"
@param str the String to start with
@return the rotated String as described here
