Create a new Java file in Eclipse. Perform the following operations: Create a new StringBuilder from the String "Prepare for your knowledge". Check the capacity of the StringBuilder if it's empty. Find the index of the letter 'y'. Delete a substring from the starting index till this index (of ‘y’). Insert a string "Good luck on " at the beginning of the StringBuilder. Append '!' to it. Print your StringBuilder to Console. Attach the screenshot of code and output.

Please use java. In this assignment, you will implement a simple class called ​CustomString​. This class represents a more customizable version of a String, with additional attributes and methods. For example, the CustomString class has a “reverse” method which returns a new string version of the current string where the capitalization is reversed (i.e., lowercase to uppercase and uppercase to lowercase) for the alphabetical characters specified in a given argument. For CustomString “abc, XYZ; 123.”, calling reverse("bcdxyz@3210.") will return "aBC, xyz; 123.". The CustomString class also has a “remove” method which returns a new string version of the current string where the alphabetical characters specified in a given argument, are removed. For CustomString "my lucky numbers are 6, 8, and 19.", calling remove("ra6") will return "my lucky numbers e 6, 8, nd 19.". There are 5 methods that need to be implemented in the CustomString class: ● getString() - Returns the current string. ●…

# For example, if you want to add a colon (:) after every character in the string "Python" you can use the following code. print(":".join("Python"))

The second picture is the code. I want the output of the code to look like picture one. What part do I have to fix? THX!
