The query should be Classic Cars AND American ones

Boolean operators such as OR, NOT, and AND create a subset of search result in a database. In this case, AND would act as an operator for intersection. In the query above, the computer will retrieve records that mention both Classic Cars and American ones only.

       String str3 = in.next();

       String oneAndTwo = str1+str2;

       if(str3.equals(oneAndTwo)){

           System.out.println(str1+" + "+str2+" is equal to "+str3+"!");
