Chapter 15, Problem 5PE

Program Plan Intro

Index of identifiers

Program plan:

Main.java

• Create a class named “Main”. Inside the class,
  • Define the “main ()” method.
    • Define the map
    • Define a key set
    • Loop that iterates for the identifiers.
    • Prompt the user to enter the input.
    • Print the resultant value.

IdentifierIndex.java:

• Create a class named “IdentifierIndex”. Inside the class,
  • Create a tree map
  • Inside the try block
    • Use necessary loop that iterates for the identifiers present in the files.
    • Loop that iterates to validate the identifier.
  • Inside the catch block
    • Catch the exception
  • Define the method “printIndex”
    • Loop that iterates for the line numbers
      • Display the identifier
