handling `zipexception: invalid cen header` in java

the `zipexception: invalid cen header` typically occurs when you are trying to read a zip file that is corrupted or not correctly formatted. the "cen" refers to the central directory structure that is part of the zip file format, which contains information about the files stored in the zip.

in this tutorial, we will discuss how to handle this exception in java using the `java.util.zip` package. we'll cover:

1. understanding the zip file structure.
2. how to catch and handle `zipexception`.
3. an example of reading a zip file.

1. understanding the zip file structure

a zip file consists of several parts:
**local file header**: contains metadata about each file in the zip.
**file data**: the actual compressed data of the files.
**central directory**: a summary of all files in the zip, which includes the local file headers and additional metadata.
**end of central directory record**: indicates the end of the zip file.

when the central directory is corrupted or improperly formatted, you will encounter the `zipexception: invalid cen header`.

2. catching and handling `zipexception`

when reading a zip file, you can wrap your code in a try-catch block to catch `zipexception`. this allows you to handle the error gracefully and take appropriate actions, such as notifying the user or attempting to recover from the error.

3. example code

here's an example demonstrating how to read a zip file and catch a `zipexception`.



explanation of the code

1. **import statements**: we import necessary classes for file handling and zip processing.
2. **main method**: this is where the program starts. we specify the path to the zip file and call the `readzipfile` method.
3. **readzipfile method**: this method opens the zip file and processes each entry.
we use a `zipinputstream` wrapped around a `fileinputstream` to read the zip file.
we iterate over each `zipentry` (file) in the zip using `g ...
