Openjdk-17 is already available in Termux Official Repository but still many of us want to install Openjdk-11 , because of many reasons.

Requirements :

• aarch64 device

Steps :

1. Download JDK tarball

   wget https://github.com/Lzhiyong/termux-ndk/releases/download/openjdk/openjdk-11.0.12.tar.xz
   

2. Create new directory for jdk

   mkdir $PREFIX/lib/jvm
   

3. Extract into new created directory

   tar -xf openjdk-11.0.12.tar.xz -C $PREFIX/lib/jvm
   

4. Create a symlink with name java into $PREFIX/bin

   ln -sf $PREFIX/lib/jvm/openjdk-11.0.1/bin/java $PREFIX/bin/java
   

Tip :

• You can create more symlinks for javac, keytool, jarsigner, etc.
