Is numeric promotion happening here? Smaller data types, namely byte, short, and char, are first promoted to int any time they’re used with a Java binary arithmetic operator, even if neither of the operands is int. If variables of different but compatible data types are involved, then implicit conversion is automatic. That means, if none of the above Rule 1 to Rule 5 applies then ternary expression will be evaluated to a type which can be assignable to both numeric operands. In previous example we learned to write simple Java program. In the J2SE platform version 1.4.2 there were four garbage collectors from which to choose but without an explicit choice by the user the serial garbage collector was always chosen. If one of the values is integral and the other is floating-point, Java promotes the integral value to the floating-point value's data type. Here is the general form to use left shift operator in Java: value << num. This is why this type of conversion happens automatically. To get the area of the division of two operands.
