Every project uses a Software Development Kit (SDK). For Java projects, the SDK is referred to as the JDK (Java Development Kit). The SDK determines which API library is used to build the project. If your project is multi-module, the project SDK by default is common for all modules within the project. Optionally, you can configure individual SDKs for each module. For more information about SDKs, see [SDK](https://www.jetbrains.com/help/idea/working-with-sdks.html) in the IntelliJ IDEA Web Help.

## Getting project SDK information
|
|
|
|
Main information about the project SDK can be accessed via [ProjectRootManager.java](upsource:///platform/projectModel-api/src/com/intellij/openapi/roots/ProjectRootManager.java) like the following example shows
|
|
|
|
```java
|
|
Sdk projectSdk = ProjectRootManager.getInstance(project).getProjectSdk();
|
|
```
|
|
|
|
## Getting and setting project SDK attributes
|
|
|
|
* To get the project level SDK
|
|
|
|
```java
|
|
Sdk projectSDK = ProjectRootManager.getInstance(project).getProjectSdk();
|
|
```
|
|
|
|
* To get the project level SDK name:
|
|
|
|
```java
|
|
String projectSDKName = ProjectRootManager.getInstance(project).getProjectSdkName();
|
|
```
|
|
|
|
* To set the project level SDK:
|
|
|
|
```java
|
|
ProjectRootManager.getInstance(project).setProjectSdk(Sdk jdk);
|
|
```
|
|
|
|
* To set the project level SDK name:
|
|
|
|
```java
|
|
ProjectRootManager.getInstance(project).setProjectSdkName(String name);
|
|
```
|
