I need help with this. This needs to be written in very simple java code (for beginners)

Write a mail merge application called MailMerge.java. Your program should read the input for the problem from System.in. The expected input will consist of three parts:

- A tag specification consisting of a list of space-separated tags on a single line, where each tag is of the form >, with an alphabet letter between two sets of angle brackets.

- A database consisting of lines of database entries, where each line has as many space-separated data items as there are tags specified in the first line of input. The database lines will conclude with a line containing only three dashes, "---".

- A template for the mail merge. All of the lines after the "---" should be considered the contents of a form letter with tags to be replaced.

Once all of the input has been read, the program should output should be a series of exact copies of the form letter template, with the occurrences of tag specifications replaced by corresponding items from the database.
