First of all, in Java, long values are represented by signed 64-bit numbers. On the other hand, int values are represented by signed 32-bit numbers. Therefore, converting a higher data type into a lower one is called narrowing type casting. As a result of these conversions, some bits wo...
Learn how to convert double long bits to double in Java. This guide covers the method and examples for effective implementation.

For the purposes of the Java programming language memory model, a single write to a non-volatile long or double value is treated as two separate writes: one to each 32-bit half. This can result in a situation where a thread sees the first 32 bits of a 64-bit value from one write,...
Java doubleToRawLongBits() method is a part of Double class that returns the long bits of the double value in accordance to IEEE 754.
If the BigDecimal is out of the possible range for a long (64-bit signed integer) result then only the low-order 64 bits are used. (That is, the number may be decapitated.) To avoid unexpected errors when these conditions occur, use the #longValueExact method. Java documentation for...

Because Java treats the byte as signed, if its unsigned value is above > 127, the sign bit will be set (strictly speaking it is not "the sign bit" since numbers are encoded in two's complement) and it will appear to java to be negative. When it gets promoted to int, bits 0 ...
intwo's complement) and it will appear to java to be negative. When it gets promoted to int, bits 0 through 7 will be the same as the byte, and bits 8 through 31 will be set to 1. So the bitwise AND with 0x000000FF clears out all of those bits. Note that this could have ...
