# MinIO Java SDK for Amazon S3 Compatible Cloud Storage [](https://slack.min.io)
|
|
|
|
MinIO Java SDK is Simple Storage Service (aka S3) client to perform bucket and object operations to any Amazon S3 compatible object storage service.
|
|
|
|
For a complete list of APIs and examples, please take a look at the [Java Client API Reference](https://docs.min.io/docs/java-client-api-reference) documentation.
|
|
|
|
## Minimum Requirements
|
|
Java 1.8 or above.
|
|
|
|
## Maven usage
|
|
```xml
|
|
<dependency>
|
|
<groupId>io.minio</groupId>
|
|
<artifactId>minio</artifactId>
|
|
<version>8.4.2</version>
|
|
</dependency>
|
|
```
|
|
|
|
## Gradle usage
|
|
```
|
|
dependencies {
|
|
implementation("io.minio:minio:8.4.2")
|
|
}
|
|
```
|
|
|
|
## JAR download
|
|
The latest JAR can be downloaded from [here](https://repo1.maven.org/maven2/io/minio/minio/8.4.2/)
|
|
|
|
## Quick Start Example - File Uploader
|
|
This example program connects to an object storage server, makes a bucket on the server and then uploads a file to the bucket.
|
|
|
|
You need three items in order to connect to an object storage server.
|
|
|
|
| Parameters | Description |
|
|
|------------|------------------------------------------------------------|
|
|
| Endpoint | URL to S3 service. |
|
|
| Access Key | Access key (aka user ID) of an account in the S3 service. |
|
|
| Secret Key | Secret key (aka password) of an account in the S3 service. |
|
|
|
|
This example uses MinIO server playground [https://play.min.io](https://play.min.io). Feel free to use this service for test and development.
