We usually add an import statement as import java.util.List;
but there is also static import statements like
import static java.lang.Math.*;
Use :-
in java when we use Math class to use methods as Math.sqrt(), Math.pow(x, a);
because all methods in Math class are static, we can make a static import as
import static java.lang.Math.*;
and can access methods as
double value = sqrt(4);
System.out.println (value); // gives 2.0
