Write a function in JAVA that takes 2 numbers in string and forms a string containing the addition of these 2 numbers?

Question

Assumption:

• The input strings will contain only numeric digits
• The input strings can be of any large lengths
• The lengths of the two input string need not be the same
• The input strings will represent only positive numbers

---

Example

If input strings are “1234” and “56”, the output string should be “1290”
If input strings are “56” and “1234”, the output string should be “1290”
If input strings are “123456732128989543219” and “987612673489652”, the output string should be “123457719741663032871”

Answer 1

 public addition(){
  String max=input1.length()>input2.length()?input1:input2;
  String min=input1.length()
  int a,b,add;
  int carry=0;
  String output="";
  int minLen=min.length()-1;
  int maxLen=max.length()-1;
  while(minLen>-1){
  a=Integer.parseInt(max.charAt(maxLen--)+"");
  b=Integer.parseInt(min.charAt(minLen--)+"");
  add=a+b+carry;
  carry=0;
  if(add>9){
  carry=1;
  add=add%10;
  }
  output=add+output;
  System.out.println(output);
  }
  max=input1.substring(0,input1.length()-input2.length());
  add=Integer.parseInt(max);
  add+=carry;
  return add+""+output;
}
