Why is java big endian

That is, all data is represented sequentially starting from the most significant bit to the least significant. Correct handling of byte order—related issues is critical when exchanging data in a networked environment that includes both big-endian and little-endian machines or when working with other languages using Java Native Interface JNI. Failure to handle byte-ordering issues can cause unexpected program behavior. The read methods readByte , readShort , readInt , readLong , readFloat , and readDouble and the corresponding write methods defined by class java.

DataInputStream and class java. DataOutputStream operate only on big-endian data. This noncompliant code example shows such a discrepancy:. This compliant solution uses methods provided by class ByteBuffer [ API ] to correctly extract an int from the original input value. It wraps the input byte array with a ByteBuffer , sets the byte order to little-endian, and extracts the int. Big endian C. Determined by the CPU running the program D.

Determined by the CPU of the compiler. For the large and small end, I think there must be many developers who haven't heard of it like me Because Java is cross platform, JVM shields a lot of underlying details and complexity for us, so it won't be touched at all at ordinary times.

The following is a large number of consultation, search and organize the results. Byte order: refers to the storage order of each byte when multi byte data is stored in the computer memory or transmitted on the network. There are two ways: big end and small end.

Big end: the high byte is stored in the low address end of the memory, and the low byte is stored in the high address end of the memory. Hexadecimal integer 0x is stored in memory. Everything in Java binary files is stored in big-endian order. This is sometimes called network order. You can freely exchange binary data electronically without any concerns about endian-ness. The problem comes when you must exchange data files with some program not written in Java that uses little-endian order, most commonly a program written in C.
