I recognize that I can't use "$line" in the second to the last lines of my code, because when the code was compiled the path /path/to/this/example.java becomes example.class. The code does not compile correctly, and therefore the last line fails to output anything as well. Unfortunately the last two lines of my code are failing to do what I want, and probably need to be revised. The only things you’ll need for this tutorial are: A running instance of a Ubuntu- or Red Hat-based Linux distribution. Well assume you have already installed these. I’ll demonstrate how this is done on both Ubuntu and Red Hat distributions. You will use the Java compiler javac to compile your Java programs and the Java interpreter java to run them.

The lines: # read -p "> $line (Press Enter to continue)"Īlso work correctly. With that said, I want to guide you through the process of writing and compiling your first C++ program on Linux. java files and place them in the file list.txt. I would like to run each file one at a time so that I can examine the students' code submission, and note any odd choices or places where there is room for improvement.Ĭurrently, the script can, correctly, find all. class files with a standard input, and record the output in a text file. My first goal is to extract the path of every class file in this parent directory 170Grading and add it to a file. In this 170Grading parent folder, there are two additional sub-folders, these subfolders are called output and runs. I unzipped this file to a parent folder on my desktop called 170Grading. When the students have submitted their files for grading, I downloaded a.

#COMPILING JAVA ON BASH WINDOWS#
If building Windows binaries, the source code must be. ((javac -d "/Users/ajm/Desktop/170Grading/runs" "$line") & (echo compiled > score)) || ((echo not compiled) > score)Įcho "" | cd "/Users/ajm/Desktop/170Grading/runs" java "$line" > score To build for Linux, pass -buildx8664-unknown-linux-gnu -hostx8664-unknown-linux-gnu to configure. You can run Java programs from the Command Prompt for quick compiling and execution. I would like to run each file one at a time so that I can examine the students code submission, and note any odd choices or places where there is room for improvement. It is also an IDE-intensive programming language, with tight integration with Eclipse. class files with a standard input, and record the output in a text file. Score="/Users/ajm/Desktop/170Grading/output/score.txt" Java is one of the most commonly used programming languages. For NetBeans, this is illustrated in the following steps. List="/Users/ajm/Desktop/170Grading/output/list.txt" If you prefer to work within an IDE such as NetBeans or Eclipse, you can compile an Oracle Java ME Embedded Client application by setting the project type to Java application, and specifying options to make the compiler generate bytecodes compatible with Java 1.4. Here is a copy of my current code: #!/bin/bash
