How to Install and Uninstall Java on Ubuntu

Step1: Installing Java on Ubuntu

You can install one or several Java packages. You can also decide which version you want on your system by installing a specific version number. The current default and LTS version is Java 11.

Install OpenJDK

1. Open the terminal (Ctrl+Alt+T) and update the package repository to ensure you download the latest software version:

sudo apt update

2. Then, you can confidently install the latest Java Development Kit with the following command:

sudo apt install default-jdk

Install Specific Version of OpenJDK

You may decide to use Open JDK 8, instead of the default OpenJDK 11.

To do so, open the terminal and type in the following command:

sudo apt install openjdk-8-jdk

Once the installation process is complete, verify the current Java version:

java -version; javac -version

How to find the OpenJDK directory with the following command:

readlink -f /usr/bin/javac

How to Set Default Java Version

As you can have multiple versions of Java installed on your system, you can decide which one is the default one.First, run a command that shows all the installed versions on your computer:

sudo update-alternatives --config java

step 2: Uninstall Java on Ubuntu

In case you need to remove any of the Java packages installed, use the apt remove or purge command. To remove Open JDK 11, run the command:

sudo apt remove default-jdk

To uninstall OpenJDK 8:

sudo apt remove openjdk-8-jdk

2nd Method:

1. sudo dpkg --list | grep -i jdk 

2. sudo apt-get purge Oracle-java8-installer

contiki ng -GNU Mode

Open the terminal

ctrl +alt + t

vl@ubuntu:~/contiki-ng$ cd tools

vl@ubuntu:~/contiki-ng/tools$ ls

vl@ubuntu:~/contiki-ng/tools$ cd cooja

vl@ubuntu:~/contiki-ng/tools/cooja$ update-alternatives --config java

// it may not change unless we do in root 

vl@ubuntu:~/contiki-ng/tools/cooja$ sudo -s
[sudo] password for vl:
root@ubuntu:/home/vl/contiki-ng/tools/cooja# update-alternatives --config.java

root@ubuntu:/home/vl/contiki-ng/tools/cooja# ant run

contiki ng -Terminal mode

open the terminal 

ctrl + alt + t

create a folder rk and copy helloworld.c and  makefile from examples folder

vl@ubuntu:~/contiki-ng/examples$ mkdir rk
vl@ubuntu:~/contiki-ng/examples$ ls
6tisch       ip64-router         nullnet            slip-radio
benchmarks   ledprg              platform-specific  snmp-server
coap         libs                rk                 storage
cplusplus    lwm2m-ipso-objects  rpl-border-router  websocket
dev          mqtt-client         rpl-udp
hello-world  multicast           sensniff
vl@ubuntu:~/contiki-ng/examples$ cd rk
vl@ubuntu:~/contiki-ng/examples/rk$ ls
vl@ubuntu:~/contiki-ng/examples/rk$ cp ../hello-world/hello-world.c .
vl@ubuntu:~/contiki-ng/examples/rk$ cp ../hello-world/Makefile .
vl@ubuntu:~/contiki-ng/examples/rk$ ls
hello-world.c  Makefile
 

Now rename hello-world.c to myown.c

vl@ubuntu:~/contiki-ng/examples/rk$ mv hello-world.c myown.c

set the Makefile to myown as shown

Now create myown.c file

#include "contiki.h"

#include <stdio.h> /* For printf() */
/*---------------------------------------------------------------------------*/
PROCESS(myown_process, "I am on My Own");
AUTOSTART_PROCESSES(&myown_process);
/*---------------------------------------------------------------------------*/
//Protothread
PROCESS_THREAD(myown_process, ev, data)
{
  static struct etimer timer;//static is used here to store the timer in RAM

  PROCESS_BEGIN();

  /* Setup a periodic timer that expires after 10 seconds. */
  etimer_set(&timer, CLOCK_SECOND * 5);

  while(1) { //super loop architecture
    printf("Hello Friends  Welcome to IoT\n");

    /* Wait for the periodic timer to expire and then restart the timer. */
    PROCESS_WAIT_EVENT_UNTIL(etimer_expired(&timer));
    etimer_reset(&timer);
  }

  PROCESS_END();
}
/*---------------------------------------------------------------------------*/

Run:

vl@ubuntu:~/contiki-ng/examples/rk$ make
 

vl@ubuntu:~/contiki-ng/examples/rk$ ls
build  Makefile  myown.c  myown.native

vl@ubuntu:~/contiki-ng/examples/rk$ make TARGET=native
make: Nothing to be done for 'all'.
 

vl@ubuntu:~/contiki-ng/examples/rk$ make clean
TARGET not defined, using target 'native'
 

vl@ubuntu:~/contiki-ng/examples/rk$ make TARGET=native
 

vl@ubuntu:~/contiki-ng/examples/rk$ ./myown.native

 

LED Display

 create a folder ledprg in contiki/examples

copy the makefile from helloworld into the above created folder 

create a file led.c in ledprg folder

//led.c

#include "contiki.h"
#include <stdio.h>

#include "dev/leds.h"
#include "dev/button-sensor.h"

PROCESS(led_process, "LED Process");

AUTOSTART_PROCESSES(&led_process);
PROCESS_THREAD(led_process,ev,data)
{

PROCESS_BEGIN();
SENSORS_ACTIVATE(button_sensor);

while(1)
{
printf("Press the Button of the sensor\n");
PROCESS_WAIT_EVENT_UNTIL(ev==sensors_event && data==&button_sensor);
leds_toggle(LEDS_GREEN);
}

printf("The sensor value is %u \n",leds_get());
PROCESS_END();
}

//Makefile

see that both the files are in the same folder ledprg

RUN THE PROGRAM:

vl@ubuntu:~/contiki-ng/examples/ledprg$ make TARGET=native

Note :

if there is an error regarding gcc version

wget http://www.netgull.com/gcc/releases/gcc-4.8.0/gcc-4.8.0.tar.bz2
 

To extract the file:

tar -xvjf gcc-4.8.0.tar.bz2

Install some additional libraries (sudo apt-get install libgmp-dev libmpfr-dev libmpc-dev libc6-dev)

Compile the source: ./gcc-4.8.0/configure --prefix=/app/gcc/4.8.0
 

Run make (This will take some time to complete. Go make some coffee, or bake some cookies. ;-))
 

Install the code: sudo make install




sudo dpkg --add-architecture i386
sudo apt update
sudo apt upgrade
