Intro to JAVA Simple Programing 1.

Please write the code according to the instruction, such as line of code required etc, in bold.

/**

Example from R15.1.

Explain what the following code prints. Draw pictures of the linked

list after each step. Just draw the forward links, as in Figure 1.

Add a static method that returns a string representation of the list

in the form:

list string version

[] /

[A] A -> /

[A,B] A -> B -> /

etc.

The expected output is:

A -> /

B -> A -> /

C -> B -> A -> /

C

B -> A -> /

B

A -> /

A

/
