VSCode can not import external libraries

I am currently trying to learn the VSCode. I am programming in Java 11 now with VSCode. In the example code below, there are 4 lines of imports. First two of them are working. But the next two of them are giving the following errors.

package app;

import java.util.*;
import java.awt.*;
import com.google.common.primitives.Ints;
import org.apache.commons.collections.iterators.ArrayIterator;

/**
 * Board_Space
 */
public class Board_Space {


}

"The import com.google cannot be resolved. Java(268435846) [5,8]"
"The import org.apache.commons.collections cannot be resolved. Java(268435846) [6,8]"

How can I solve this errors and how can I use any kind of external libraries?
