I'm trying to do compare it but I have this query can I compare every condition with one go? Like

if(exp.charAt(i)=='+','-','/','*')

I know I have to do something like this which is correct but i'm trying to find a short way to to this. if(exp.charAt(i)=='+',exp.charAt(i)=='-',exp.charAt(i)=='/',exp.charAt(i)=='*'

You could put the characters into a string, and check if the string contains the specific character in your array:

String matchingCharacters="+-/*";
if (matchingCharacters.contains(exp.charAt(i)))
    ....
