Read the description of indexOf(String str, int fromIndex). Notice that there are two indexOf methods, however, they have different parameters. What are the differences between indexOf(String str)text annotation indicator and indexOf(String str, int fromIndex)text annotation indicator? The substring method also occurs twice. Read the description so you understand the difference between the two.

Once you understand what each method does, add lines to StringExplorer that illustrate each of the methods in the table. Include comment lines that state each method you are demonstrating as shown in the two examples.
