Adding java output to echo string of bat file

I need to assign Standard out of java application added to an echo string of a bat file. Lets say java application writes "hello world" via System.out.println.

For an example I have a bat file mybat.bat.

 @echo off

    echo output=java -jar E:\FYP\MyApp\out\artifacts\MyApp_jar\MyApp_jar\MyApp.jar %1

which does not give the output=Hello world

How can I achieve that. Your help is really appreciated.

Thank You !

As far as I understand you - you want to assign the output of the java to variable. May be this will do this for you:

@echo off
set "java_output="
setlocal enableDelayedExpansion
for /f "delims=" %%J in ('java -jar E:\FYP\MyApp\out\artifacts\MyApp_jar\MyApp_jar\MyApp.jar %1') do (
      set "java_output=!java_output! %%J" 
)
endlocal & set java_output=%java_output%
echo %java_output%

You need to use for command to get the output of a program and assign it to a variable.

  @echo off
    for /F "tokens=*" %%o in ('java -jar E:\FYP\MyApp\out\artifacts\MyApp_jar\MyApp_jar\MyApp.jar %1') do set output=%%o
    echo %output%
