The default value of a character type is /u0000'. Conclusion That's all about the 8 essential data types in Java. It's must for every Java developer to not just know about these data types but also how and when to use them. You should also know what are their size like how many...
Another difference between byte and char in Java is that the size of the byte variable is 8 bit while the size of the char variable is 16 bit. One moredifference between char and byteis that byte can representnegativevalues as well but char can only representpositivevalues as its range is...
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 10月前 24阅读 c的...

Actually a pointer is just a address holder so its size is always that of an int data type,what ever may be the type of pointer.In a 16-bit compiler,its 2 bytes and in 32-bit compiler,its 4 bytes(ie depeds on sizeof(int)) Was this answer useful? Yes Replyshivam...
