Question

There are some data types which are present in C but not available in Java. I have listed some of them and written their substitute in Java. Please suggest if i have done it correctly or some changes should be made:

unsigned char -> short

unsigned short -> int

unsigned char *x -> short[] x

unsigned short *x -> int[] x

char *x -> String

unsigned int -> long

Answer 1

For unsigned char you should use Java’s char, which is also unsigned. The others are OK inasmuch as they are injective (assuming commonly used sizes in C), i.e. they will preserve values, though the matter is rather more complicated with pointers/arrays.
