For example, we can print the messages in the standard output using theSystem.out.println()method.Systemis a class injava.langpackage that has astaticvariable namedout. When we useSystem.out, we are referring to thatstaticvariable out of theSystemclass. We can use astatic importstatement to ...
import static java.lang.Math.*; If you do this you can directly use the math functions y=pow(x,3) You can also import a specific function or constant import java.lang.Math.pow; This statement imports just the pow function. However, it is advisable to use static imports sparingly since ...

How does let in for loop work? I understand how "var" works and I'm quite used to it - the scope is functional. However the let statement is far from clear. I understand is has block scope, but why does THAT matter in the... ...
