How to run Java code after compiling?

[leonko]

Bat update:

Code: Select all

@ECHO OFF
javac %1.java
if  errorlevel  1  goto  error
echo [OK, running... ]
java %1
goto  end
:error
echo  [Compile was unsuccessful]
goto  end
:end

Little error in your sh script. you have "javac" twice. The second one should be "java"

should be:

Code: Select all

$ cat javacr.sh
#!/bin/sh
javac $1.java
java $1

Thank you, its typos.

Better use this code:

Code: Select all

@ECHO OFF
javac %1.java
if  errorlevel  1  goto  error
echo [OK, running... ]
java %1
goto  end
:error
echo  [Compile was unsuccessful]
goto  end
:end

Because when you re-compiling your code and have an error, our old java class does not start. It's better.

hi

In Mac , in which directory i save this code?

Thanks

@elgreen,

save this in your /usr/bin/

Hey guys,

thanks for the tipps...could finally do it =)...I'm on Mac OS X 10.7 running ST2bd2139.

I tried to implement the error handling in the .sh script and I also had to modify it to make it work, don't know why but the whole $ cat filename thing made it not work and I also had to change the shebang part to /bin/bash instead of /bin/sh...so here's what I came up with

This is the file javacrun.sh in folder /usr/bin/

Code: Select all

#!/bin/bash
echo "Compiling Java sourcecode..."
javac $1.java
if [ $? == 0 ]; then {
   echo "Running the compiled code..."
   java $1
} else {
   echo "Compiling error, no .class file created"
} fi


for this I created a new build system called JavaCRun.sublime-build with the following code inside:

Code: Select all

{
   "cmd": ["javacrun.sh", "$file_base_name" ],
   "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
   "working_dir": "${file_path}",
   "selector": "source.java"
}


it works so far so good, when the code has no errors it makes the desired .class file and runs it. This works good with "Hello World"-type (very simple) programs but it doesn't really good with programs which require user input (when I run it in Terminal I get prompted to enter something like a number or so, I can't do this in the sublime text "console"). The code is compiled successfully and the .class file is created but when the script runs the .class file, it doesn't work good because I can give the needed user input...

is this a limitation from sublimetext console or is there a way to solve this and allow userinput in sublime text?

thanks for your replys!

Bumping this up, it would be really nice if there was a way to do this.

To answer your question, ST2 does not allow for interactive input. That's why I find it most convenient to use iTerm's fullscreen visor (http://www.iterm2.com) plus @wbond's Terminal plugin to quickly run java programs. I build the file in ST2, then I set iTerm to appear and disappear on a keystroke and run with iTerm. Hopefully ST2 will allow for interactive input in the future but I don't think it's top priority atm.

Hope that helps.

Like C0D312, I solve this by using iTerm and @wbond's terminal plugin. I did make a slight change to the iTerm.sh file within the Terminal plugin. Every time you run it, it opens a new terminal. I didn't like this so I altered it to just use the current terminal. This way I just build in SB2, cmd + shit + t, and now i'm at the directory in iTerm. From here I just use a text expander snippet to build. It's not perfect, but just a few keystrokes and its done.

Here is my altered file.

Code: Select all

#!/bin/bash

CD_CMD="cd "\\\"$(pwd)\\\"" && clear"
VERSION=$(sw_vers -productVersion)

if (( $(expr $VERSION '<' 10.7) )); then
   RUNNING=$(osascript<<END
   tell application "System Events"
       count(processes whose name is "iTerm")
   end tell
END
)
else
   RUNNING=1
fi

if (( $RUNNING )); then
   osascript<<END
   tell application "iTerm"
      activate
      set term to (current terminal)
      tell term
         set sess to (current session)
         tell sess
            write text "$CD_CMD"
         end tell
      end tell
   end tell
END
else
   osascript<<END
   tell application "iTerm"
      activate
      set sess to the first session of the first terminal
      tell sess
         write text "$CD_CMD"
      end tell
   end tell
END
fi

Sorry to bump and old thread.

This is working fine for me.

But if I want to import another library, when I build and run it fails.

The output says it can't find the library.

When I run javac from the command line it works fine though. CLASSPATH is configured correctly.

Any ideas?

Have searched around and am failing to come up with any thing.

Cheers
