Java BrokenReader-class And Method Code Example

Here is an example of how to use the BrokenReader class from the Apache Commons IO library in Java:


public class MyClass {
    public static void main(String[] args) throws IOException {
        StringReader input = new StringReader("This is an example text");
        BrokenReader brokenReader = new BrokenReader(input);
        brokenReader.setBroken(true); // set the reader to be broken
        int nextChar =;
        while (nextChar != -1) {
            // do something with the character
            nextChar =;

In this example, BrokenReader is wrapping a StringReader that contains the string "This is an example text".

It can be used to simulate a broken reader by throwing an IOException when the read() method is called after the reader has been set to be broken by calling setBroken(true).

This allows to simulate the behavior of a broken reader, testing the exception handling of code that uses this reader.

Please note that this is a simple example, in real-world usage, you might want to do more complex processing on the characters before returning them.
