Header files

A file with an extension that has some predefined declarations and definitions is called a header file. Every computer program imports a set of header files to perform common tasks such as getting input, displaying output, and so forth. Every language has different header files (such as C, JAVA, Python, and C++). In this article, header files are explained mainly in the context of the C/C++ language.

Instructions
Task: Exception handling
This program will be reused in the next lab. Save it at a
safe place.
Write the bin2Dec(String binaryString) method to
convert a String representing a binary number into a
decimal number (assume it fits into an int type).
Implement the bin2Dec method to throw a
NumberFortmatException if the string is not a binary
string.
Write a test main method, in the same class, that
prompts the user to enter a binary number as a String
and displays its decimal equivalent. If the bin2Dec
method throws an exception, display "Not a binary
number:" followed by a space and the input string. This
message (for example, "Not a binary number: 123" in
the sample runs) should be put as the message field in
the exception object, which will be returned by the
getMessage() method. Below are sample runs.
Enter a binary number: 101
The decimal value for binary number 101 is 5
Enter a binary number: 110110110
The decimal value for binary number 110110110 is 438
Enter a binary number: 123
Not a binary number: 123
