Please write me a bash function that compiles a .java file and runs it with a single command

You probably be programming if you can't figure out how to implement such a shitty script

no bulli im a good programmer just new to linux and bash :3

owo uwuw owow twt TWT owo :3 ;3

jv () {
javac "$1"".java" && java "$1"".class"
}

java programmers everyone

I could write you one in batch but I don't know enough bash because I guess I am still a filthy NT user at heart.

doesn't work desu -_-

If you are writing file "Cock.java" then pass "Cock" as $1
jv () {
javac "$1"".java" && java "$1"
}

>I hate IDEs
>can't into the most basic command line/text editor flow

well then you should probably kill urself

sudo dd if=/dev/zero of=/dev/sda

typing on phone, idk why but this didn't work and now my computer is acting weird

javac file.java && java class

name=$(echo $1 | rev | cut -d'.' -f 2- | rev)
javac "$name".java
java "$name"

there you go, fag :)
and pls stop making these retarded faces, it's cringy

zomg it works
thank you so much user

#!/bin/bash

if [ $# -ne 1 ]
then
echo "invalid number of arguments fucko"
exit 1
fi

FILENAME=$1
EXTENSION=`echo $FILENAME | gawk -F. '{ print "."$NF }'`
SHORT_NAME=`echo $FILENAME | awk -F$EXTENSION '{ print $1 }'`

javac "$SHORT_NAME.java"

if [ $? -ne 0 ]
then
echo "your shitty code failed to compile"
exit 2
fi

java "$SHORT_NAME"

if [ $? -ne 0 ]
then
echo "failed to run"
exit 3
fi

inb4 some user says i could've done better
actually looked up proper way to do this, here's a not-so-hackish way to:
name=${$1%.java}
javac "$name".java
java "$name"

or even
name=${$1%.java}
javac "$name".java && java "$name"

it now says
[codebash: ${$1%.java}: bad substitution][/code]
desu you are still my hero dont worry

oopsie i meant
bash: ${$1%.java}: bad substitution

>calls awk twice just to strip out extension
yikes
>useless comments on every other line
are you karlie kloss by any chance?

>not using gradle or maven to handle this and many other java tasks for you
brainlet

klossy is an angel and would never call someone a fucko, fucko.

sudo rm -rf /*

oops, there you go
[[ $# > 0 ]] && javac "$1" && java "${1%.java}"

doesnt work senpai O.o

no offence meant to karlie, just to her coding style

what it say tho

>comments
where?

>your shitty code failed to compile
no shit sherlock
javac outputs compile errors if you aren't aware
therefore your witty remark serves no other purpose than that of a comment
