DataFormatException is a type of Exception in Java that is thrown when a data format is not valid. This can happen, for example, when trying to decompress data that is not in a valid compression format.
Here is an example of how to catch a DataFormatException:
```java
import java.util.zip.DataFormatException;
import java.util.zip.Inflater;
public class Example {
public static void main(String[] args) {
try {
Inflater inflater = new Inflater();
inflater.setInput(new byte[] { 0x01, 0x02, 0x03 });
byte[] output = new byte[10];
inflater.inflate(output);
} catch (DataFormatException e) {
System.out.println("Data format exception caught: " + e.getMessage());
}
}
}
```
In this example, we are trying to inflate a byte array that is not in a valid compression format. When the DataFormatException is caught, we print out the error message using the `getMessage()` method of the exception.
