why have 2 versions of java ?

  1. the jdk oracle , 1 openjdk.
  2. and why openjdk available linux ?
  3. and on wikipedia,i find java open source .but ,i find copyright information inside oracles jdk saying restricted ???

  1. open jdk trying reinvent wheel giving freedom of choice (you can use cool openjdk jvm or mainstream oracle one)

  2. if cool it's linux

  3. that question out of scope, besides i'm not sure myself...
