To determine if your Odroid SBC is powerful enough to run a Minecraft server, you should first check its specifications, particularly the CPU and RAM. For a basic Minecraft server with a few players, a minimum of 1-2 GB of RAM and a dual-core CPU should suffice. However, if you plan to host more players or use mods, you may require more resources. Keep in mind that running other services on the same device may also impact its performance.

To install Java on your Odroid SBC, follow these steps:

1.Open a terminal window on your Odroid SBC.
2.Update your package list by running the command:
```
sudo apt update
```

3. Install the default Java Development Kit (JDK) by running:
```
sudo apt install default-jdk
```
4.Verify the installation by checking the Java version:
```
java -version
```

Once Java is installed, you can proceed with setting up the Minecraft server:
1.Create a directory for your Minecraft server files:  `mkdir minecraft_server && cd minecraft_server`
2.Download the Minecraft server JAR file from the official website: `wget https://launcher.mojang.com/v1/objects/<server_version>/server.jar`
Replace <server_version> with the appropriate version identifier from the official website.
3.Make the JAR file executable: `chmod +x server.jar`
4.Run the server for the first time to generate the necessary files: `java -Xmx1024M -Xms1024M -jar server.jar nogui`
Adjust the memory allocation (`-Xmx` and `-Xms`) according to your available RAM.
5.Accept the EULA by editing the `eula.txt` file and changing `eula=false` to `eula=true`.
6.Start the server again with the same command as in step 4.

Your Minecraft server should now be up and running on your Odroid SBC. You can customize the server properties by editing the server.properties file, and manage the server through the terminal or by using third-party tools.
