OpenJDK

OpenJDK is the open-source reference implementation of the Java Platform. Includes the JVM, compiler (`javac`), and standard library.

Java's official builds at jdk.java.net do not include riscv64 binaries. RISC-V support was added to OpenJDK but prebuilt binaries are not distributed officially. This build enables Java development and application deployment on RISC-V hardware without a multi-hour build from source.

```bash

wget https://github.com/Cloud-V-10xE/RISC-V-softwares/releases/latest/download/openjdk--riscv64-linux.tar.gz

sudo tar -xzf openjdk--riscv64-linux.tar.gz -C /usr/local/
