For example, the program should: ouput the individual digits of 3456 as 3 4 5 6 and the sum as 18, output the individual digits of 8030 as 8 0 3 0 and the sum as 11, output the individual digits of 2345526 as 2 3 4 5 5 2 6 and the sum as 27, output the individual digits of 4000 as 4 0 0 0 and the sum as 4, and output the individual digits of -2345 as 2 3 4 5 and the sum as 14.

Thanks in advance for your help.

astringNum = String.valueof(aNum);

for(int count =0; count < aStringNum.length(); count++)

{

digitAt = aStringNum.charAt(count);

adigit = character .getnumericvalue(digitAt);
