Bash script command output error when splitting up and convert to int

I create a bash script to read the output from another command (java -jar ...).

The result from the command is like below:

MIN,MAX
6165350,6228865

I omit the first line using head -2 | tail -1 so the output will become

6165350,6228865

And i save it to the variable called output

output=$(java -jar bundletool.jar get-size total --apks=$APKS_PATH | head -2 | tail -1)

Last, I create java file to split the output results

import java.util.*;

public class Demo {
    public static void main(String[] args) {
        String[] values = args[0].split(",");

        System.out.println(Integer.parseInt(values[0]));
        System.out.println(Integer.parseInt(values[1]));
    }
}

And below is the final bash script

#!bin/bash
output=$(java -jar bundletool.jar get-size total --apks=$APKS_PATH | head -2 | tail -1)
java Demo $output

When i run the bash, why i'm getting the error

6165350
"xception in thread "main" java.lang.NumberFormatException: For input string: "6228865
        at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
        at java.base/java.lang.Integer.parseInt(Integer.java:652)
        at java.base/java.lang.Integer.parseInt(Integer.java:770)
        at Demo.main(Demo.java:8)

I get the correct results when i try to change the output

output="6165350,6228865"

Thank you

I suspect that there is a \r at the end of the last argument, which explains why Exception is spelled "xception.

You can confirm that it is the case by pipe the output to a hex dump.

java -jar bundletool.jar get-size total --apks=$APKS_PATH | head -2 | tail -1 | xxd

You can trim the \r of with tr -d '\r' in the bash part or strip the argument in the Java part.

String[] values = args[0].strip().split(",");

If there is a non-printing character there, typically the String#strip method will remove it.
String#trim may work, also.

Try the following.

public static void main(String[] args) {
    String[] values = args[0].split(",");

    System.out.println(Integer.parseInt(values[0].strip()));
    System.out.println(Integer.parseInt(values[1].strip()));
}

Since you mentioned that your bundletool.jar produces a carriage return as line ending, I would (if you can not change the Java program to produce reasonable line endings) simply do a

nums=( $(java .... bundletool.jar ... |dos2unix|awk -F , '{print $1, $2}') )

You then have the first number in ${nums[0]} and the second one in ${nums[1]}
