in the go language they are string constants (containing string value), numeric constants (containing an integer and floating values), Boolean constant (containing true and false value). In general programming, the constants are defined at the top of the program and will be available for the ...
Let’s take a look at two common use cases for compile-time constants in Java. 6.1. Switch Statement When defining the cases for a switch statement, we need to adhere to the rules defined in the Java language specification: The case labels of the switch statement require values that are ...
The values of enumerated constants begin with 0 for the first in the set and count upwards by 1. So RED equals 0, BLUE equals 1, GREEN equals 2, WHITE equals 3, and BLACK equals 4. All the values are integers. Constants also can specify their value using an = assignment operator: en...
