So they can be invoked as if they are a mathematical code library.
The methods of the Math
class in Java are declared as static because the Math
class is designed to provide utility functions for mathematical operations, and there is no need to create an instance of the Math
class to use these methods. Declaring the methods as static allows them to be accessed directly using the class name, without the need for instantiation.
For example, you can call a method from the Math
class like this:
double result = Math.sqrt(25.0);
If the methods were not static, you would need to create an instance of the Math
class before using its methods, which would be unnecessary and counterintuitive for a utility class like Math
. Making the methods static allows for a more straightforward and convenient usage pattern.
