This post desribes about how can we install jdk in intel edison board in Yocto operating system. If apt or rpm commands were not found just follow the steps,

Create a directory name java under the /usr/
                                     

root@edison:~# mkdir /usr/java

root@edison:~# cd ~

download the jdk file using wget command

  wget --no-check-certificate --no-cookies - --header "Cookie: oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u67-b01/jdk-7u67-linux-i586.tar.gz"


Extract the tar file,
 
root@edison:~# tar -xvzf  jdk-7u67-i586.tar.gz

Now move the directory  jdk1.7.0_67 into /usr/java
 
root@edison:~# mv  jdk1.7.0_67 /usr/java/.

Now configure the java environment variables
 
root@edison:/usr/java#  JAVA_HOME=/usr/java/jdk1.7.0_67 

root@edison:/usr/java#  export JAVA_HOME

root@edison:/usr/java#  PATH=$JAVA_HOME/bin:$PATH

root@edison:/usr/java#  export PATH

root@edison:/usr/java#  java -version


ecjava version "1.7.0_67"

Java(TM) SE Runtime Environment (build 1.7.0_67-b01)

Java HotSpot(TM) Client VM (build 24.65-b04, mixed mode)
root@edison:/usr/java# echo $JAVA_HOME

the following lines to be added in /etc/profile file.
