Run 30 jar from batch and save the output result for each jar

Question

Hi i have a question about running several jar files in the same folder by batch file. I need to create a loop and read all the jar files name, and run them all, and create output for all jars. like this code:

cls
cd\ 
cd C:\java\
set PATH=%PATH%;C:\Program Files\Java\jdk1.8.0_20\bin;
cls

javac -jar "here come the name from the folder"

jarname < input1+"the name of the jar".txt > output1+"the name of the jar".txt 

Answer 1

How about something like:

for %%j in (*.jar) do (
java -jar "%%j" < "input%%~nj.txt" > "output%%~nj.txt"
)
