The Narrowing Conversion
<![CDATA[
The narrowing conversion occurs from a type to a different type that has a smaller size,
such as from a long (64 bits) to an int (32 bits).
In general, the narrowing primitive conversion can occur in these cases:
short to byte or char
char to byte or short
int to byte, short, or char
long to byte, short, or char
float to byte, short, char, int, or long
double to byte, short, char, int, long, or float
The narrowing primitive conversion must be explicit.
You need to specify the target type in parentheses.
public class MainClass {
public static void main(String[] args) {
long a = 10;
int b = (int) a; // narrowing conversion
System.out.println(a);
System.out.println(b);
}
}
