What is the largest negative integer and largest positive integer that can be represented by a "short" (or "int" or "long") Java data type? | |
Louisiana automobile license plates have six "digits" composed such that the left-most three digits are letters of the alphabet (A-Z) and the right-most three digits are numbers (0-9). For example, [AHH 309]. What is the largest number of license plates that can be produced if you demand that they have unique 6-digit identifications? |
What Java byte integer is represented by the 8-bit binary sequence 0001 0110 ? What about the sequence, 1110 1010 ? What is the hexadecimal representation of both of these [Java byte] integers? | |
What 8-bit binary sequence represents the [Java byte] integer -128 ? What binary sequence represents the integer +127 ? Add these two binary sequences together and examine whether or not the answer is the correct 8-bit binary sequence representation of the [Java byte] integer -1 . |
What 8-bit binary sequence represents the [Java byte] integer -22 ? What binary sequence represents the integer +26 ? Add these two binary sequences together and examine whether or not the answer is the correct 8-bit binary sequence representation of the [Java byte] integer +4 . |
