A Java program can have the following type of delimiters: {, }, (, ), I, and 1. In a correct Java program, these delimiters must be properly nested. Think of each left delimiter (, (, and [ as opening a scope, and think of each right delimiter }, ), and ] as closing a scope opened by a corresponding left delimiter. A string of characters containing these delimiters has proper nesting of delimiters if each scope that is opened is eventually closed, and the scopes are opened and closed in a last- opened-first-closed fashion.

![4. Properly Nested Delimiters
A Java program can have the following type of delimiters: (, }, (, ), [, and 1. In a correct Java
program, these delimiters must be properly nested. Think of each left delimiter (, (, and [ as opening
a scope, and think of each right delimiter }, ), and ] as closing a scope opened by a corresponding
left delimiter. A string of characters containing these delimiters has proper nesting of delimiters if
each scope that is opened is eventually closed, and the scopes are opened and closed in a last-
opened-first-closed fashion.
Write a program that reads a file containing Java source code and checks it for proper nesting of
delimiters. Your program should read the source code from the file and print it to the screen. If the file
is properly nested, all of it is printed to the screen and a message is printed that the file is properly
nested. If the file is not properly nested, then copying of the file to the screen stops as soon as
improper nesting is detected, and your program prints a message that the file has errors. To simplify
your task, you may assume these delimiters do not appear inside of comments and string literals, and
that they do not appear in the program as character literals.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F876247bf-92ad-4abe-9ca8-e5add41752dc%2F395306d2-4ead-4ebc-805c-70df1d186b32%2F3xogyue_processed.jpeg&w=3840&q=75)
