The document discusses static imports in Java. It shows an example of using the Math class's pow and sqrt methods with and without static imports. It demonstrates how static imports allow calling the methods directly without specifying the class name. It also shows importing all static members from a class using a wildcard. The document provides links to learn more about Git/GitHub and joining a forum for questions and a course certificate.

2. Hands On!

3. double a = 2;
double b = 3;
double c = 4;
System.out.println(Math.pow(a, b));
System.out.println(Math.sqrt(c));

4. System.out.println(pow(a, b));
System.out.println(sqrt(c));

5. import static java.lang.Math.pow;
import static java.lang.Math.sqrt;
public class StaticImport {
public static void main(String[] args) {
double a = 2;
double b = 3;
double c = 4;
System.out.println(pow(a, b));
System.out.println(sqrt(c));
}
}

6. import static java.lang.Math.pow;
import static java.lang.Math.sqrt;
public class StaticImport {
public static void main(String[] args) {
double a = 2;
double b = 3;
double c = 4;
System.out.println(pow(a, b));
System.out.println(sqrt(c));
}
}

7. import static java.lang.Math.*;
public class StaticImport {
public static void main(String[] args) {
double a = 2;
double b = 3;
double c = 4;
System.out.println(pow(a, b));
System.out.println(sqrt(c));
}
}
