How to write and compile a java program in ubuntu

Updated Introduction This tutorial describes how to set up a complete and free toolchain for STM32F4xx microcontrollers, including how to use hardware floating point support. It is mostly aimed towards beginners with ARM microcontrollers, however, experienced developers could probably find something useful here as well.

It is assumed that the reader is a bit familiar with the C programming language and the Bash terminal. Open a terminal and use the following command: You can download the modified version here: Unzip the files to some directory and run the script: For the path update to take effect you have to log out and log in again.

I have experienced that the texinfo version included with Ubuntu In that case, downgrading it could help: When the summon-arm script finishes, you should be able to build programs for the STM32F4 and many other microcontrollers and use hardware floating point support.

A simple performance test for hardware floating point speed is also included. All of the latest ST standard peripheral libraries are included as well. You can download the project here: If you connect the RX line of a 3.

This way you can print debug information, which can be very useful when dealing with peripherals. Do not connect any RS cable to these pins, as these voltage levels will damage the stm32f4. You can also use the micro-usb port on the stm32f4-discovery if you follow the instructions in this post.

If you want to experiment with the hardware floating point support, look at this part in the makefile: Also note that you should use the bit float version of the standard math libraries sinf, powf, sqrtf etc, they have an f at the end to take advantage of the hardware floating point unit.

When using the Linaro-GCC version of the original summon-arm-toolchain script, bit double will not work when using hardfloat at least it did not for me.

So the change to Linaro-GCC was necessary. But remember, as the hardware floating point unit does not support bit double, those operations will be done in software; which is up to times slower than using bit float. I personally like Eclipse as it is really useful with code-completion, source navigation, syntax checking etc.

You can also install alacarte to add eclipse to the unity launcher, gnome menu etc. Add the following source http:Hello World in Java on Linux. Now you are ready to write your first Java program. You will develop your Java programs in an application called DrJava. DrJava features many specialized programming tools including syntax highlighting, bracket matching, auto indenting, and line numbering.

3. Compile a Program from DrJava. The topic is very easy and i am sure that lots of java programmer already know how to compile java program existing in package.

However there are users who frequently works on eclipse, netbeans or any other IDE and don’t know that how the program actually works behind the IDE. Hi Rich, I am a Java developer, using so far Ubuntu/OS X exclusively for my developing needs.
