To define non-integral constants, one approach is to group them in a single static class namedConstants. This will require that all references to the constants be prefaced with the class name, as shown in the following example. Example ...

If a class defines a constant property with a value that is a handle object, you can assign values to the handle object properties. To access the handle object, create a local variable. For example, the ConstMapClass class defines a constant property. The value of the constant property is...
In the above program, we created a constantPIusing thedefine()function that contains value 3.14. Then we created a local variable$radiusinitialized with 5. Then calculate the area of the circle and print the result on the console screen. ...
