The main difference is, the computer does it in base 2 instead of base 10. When you divide with '/', the result is the quotient, and the remainder is thrown away. When you divide with '%', you get the ...
WebFeb 14, 2024 · For int, this minimum range is -32767 to 32767, meaning an int must be at least 16 bits wide. An implementation is free to provide a wider int type with a correspondingly wider range. For example, on the SLES 10 development server I work on, the range is -2147483647 to 2137483647. WebMar 2, 2013 · The Java programming language uses two's-complement representation for integers, and the range of two's-complement values is not symmetric, so negation of the maximum negative int or long results in that same maximum negative number. Overflow occurs in this case, but no exception is thrown. For all integer values x, -x equals (~x)+1.

A "byte" can represent an integer from 0 to 255, or a single ASCII character, or anything else that there are 256 of. The Java language designers chose to use integers -128 to 127 for the byte datatype. 8 bits gives 256 different values ; the rest is a matter of convention.
WebNov 13, 2015 · The reason why Java doesn't throw an exception and you receive negative numbers has to do with the way numbers are stored. For a long primitive the first byte is used for indicating the sign of the number (0 -> positive, 1 -> negative), while the rest are used for the numeric value.
WebSep 1, 2012 · If a and/or b can be negative, you must (i) be careful not to get an overflow already for the difference check and (ii) perform a similar check for the minimum.
