You can compare long and int directly however this is not recommended.
It is always better to cast long to integer before comparing as long value can be above int limit

long l = Integer.MAX_VALUE;       //2147483647
int i = Integer.MAX_VALUE;        //2147483647
System.out.println(i == l);       // true
 l++;                             //2147483648
 i++;                             //-2147483648
System.out.println(i == l);       // false
System.out.println(i == (int)l);  // true

Yes, that's fine. The int will be implicitly converted to a long, which can always be done without any loss of information.
