Java output as variables within same shell script

Question

I'm running JAVA code inside shell script

java -cp ojdbc6.jar:. javaClassName args

Is it possible to do command substitution for java output inside shell

Output of java code is an array:

[{ID:143},{Name:John},{Age:32},{Designation:Enginner},{City:Delhi},{Phone:+123 456 789},{Email:[email protected]}]

I want to declare above array as variables inside the same shell-script where java code runs

ID=${ID}
Name=${Name}

So: 1.1. Separate input by the comma 2. Extract the relevant strings 3. Parse the text to create a string or strings ID=143 Name=John Age=32 etc. 4. Then re-evaulate the strings or best use declare or use read to read the values into current shell. Utilities like tr sed awk will be helpful. What have you tried? Are you stuck somewhere? — KamilCuk

Try

grep -oE '(:[^}]+)' |  head -2  | tr -d ':'

Demo :

$read -r Id Name <<<$(echo '[{ID:143},{Name:John},{Age:32},{Designation:Enginner},{City:Delhi},{Phone:+123 456 789},{Email:[email protected]}]' | grep -oE '(:[^}]+)' |  head -2  | tr -d ':' )
$echo $Id
143
$echo $Name
John
$
