Thanks Vishal, my code is working now and I will post the full version of this code together with the functions like subtraction division multiplication etc.

Since op is Char data type it must be enclosed with single quotation and use op.equals('+'). Alternately you can use op as data type string.

int no_1=sc.nextInt();

Change op variable type to String, @Hemant Jaiswal. Also in if condition change to op.equals("+") .
