JRegistry
A Java Wrapper for the Windows Registry
#A Java library for accessing the power of the Windows Registry
This is a java wrapper for the Windows functions that operate on the registry. Some of the methods available in this library include read/write operations as well as the ability to search the registry for specific values. JRE 1.5 or higher required.
#Features
- Reading from / Writing to the Windows Registry
- Retrieving a sub-key listing as a sorted / unsorted array
- Iterating over sub-keys without using an array
- Retrieving a list of values as a sorted / unsorted array
- Iterating over values without using an array
- Copying whole registry sub-trees to another section of the registry
- Searching a sub-key for a specific value (can be a string or binary match)
- Listening for registry changes such as when a key or value is created or deleted
- Export a key to .reg file that is compatible with the Windows Registry Editor
#Examples
Below are a few examples of how to use JRegistry. For a complete look at the library’s capabilities, take a look at the documentation. The RegistryKey
class contains the starting point for this library.
// Create a RegistryKey object with the root key as HKEY_CURRENT_USER
RegistryKey software = new RegistryKey("SOFTWARE");
// software represents the path HKEY_CURRENT_USER\SOFTWARE
// Can also include sub-keys
RegistryKey myapp = new RegistryKey("SOFTWARE\\myapp");
// myapp represents the path HKEY_CURRENT_USER\SOFTWARE\myapp
// If you need to create the key, add a second parameter with the value true
RegistryKey myapp = new RegistryKey("SOFTWARE\\myapp", true);
// Get a list of all the root keys
RegistryKey[] roots = RegistryKey.listRoots();
// Get a list of values from the key
List<RegistryValue> values = myapp.getValues();
// Get a single value
RegistryValue value = myapp.getValue("name");
// Delete the key
int code = myapp.deleteKey();
