Short and int are datatypes of two different sizes. You'll have to cast the short as an int.

int i = 20;
short s = 25;

i = (int)s;

No that doesn't work, same problem.

Also, the following code works, so its not a problem, you can fit a smaller data type in to a larger one e.g short into an int but not the other way round, thats when casting is necessary but it's not the solution to this problem.

int i=20;
short s = 25;
int b = s;

can anyone else help?

Can you please post the full error and maybe the method the problem is in

Where are you writing those lines of code?

"i = s" has to be within a method. I suspect you have entered these outside of a method which would explain why "int b = s" works.

You need to do something like.

Class example {
  int i = 20;
  short s = 25;
  // i = s will not work here.
  int b = s;  // This will work here.

  public static void main(String[] args) { 
     i = s;
  }

  public static void thisWorksAsWell() {
     int i = 20;
     short s = 25;
     i = s;
     int b = s;
  }

}
