Do while needs to run opposite of how it's going

Code Help
1

class Main {
public static void main(String args) {
int num = 1;

do {
System.out.println(num);
num++;
} while (num <= 10);

int Num = 1;
do {
System.out.println(Num);
Num++;
} while (Num <= 20);
}
}

This is what the output supposed to be:
