Java identifiers are case-sensitive. 3BlindMice B. If a=4; and b=3; then after the statement a=b; the value of b is still 3. A C++ identifier can start with a digit. Using the Luhn formula on the identifier portion, the check digit is calculated as follows: This identifier should remain consistent across reboots or upgrades of Presto. The valid rules for defining Java identifiers are: It must start with either lower case alphabet[a-z] or upper case alphabet[A-Z] or underscore(_) or a dollar sign($). The operands of the modulus operator must be integers. An identifier can begin with a letter, dollar sign, or underscore, but not a digit.
