error with import java.io.*

[osval]

This error appears when I run a program with java.io imported.

Code:

Error
c:\demo\IOStreamDemo.java:2: cannot access java.io
bad class file: \java\io.class
class file contains wrong class: io
Please remove or make sure it appears in the correct subdirectory of the classpath.
import java.io.*;
^
1 error

Tool completed with exit code 1

Lets see the whole code.

[Swamipsn]

java.io class file or related JAR may be damage or corrupt. Pls try to open than using any of text editor, if its open then download the JAR again and copy it to your JDK forlder

[cruxblack]

A damaged IO library?
that's quite rare, which Java version ur using?

your compiler assumes java.io is a class, not a package.
We may need to see your real code that has generated the error.

Reinstalling JDK etc. are irrelevant if other API packages can be imported normally.
