unsigned char java ## unsigned char in Java In Java, the `unsigned char` data type is not natively supported. Java only has a limited set of primitive data types, and `char` is one of them. However, `char` in Java is a Java sed ide 原创 mob649e815b5994 2024-02-01 11:49:...

所以,int,long int,short int的宽度都可能随编译器而异。但有几条铁定的原则(ANSI/ISO制订的): 1sizeof(shortint)<=sizeof(int)2sizeof(int)<=sizeof(longint)3shortint至少应为16位(2字节)4longint至少应为32位。 unsigned 是无符号的意思。
