Create a random number between 10 and 300 (inclusive) and assign it to a variable called n
Print n greetings as described below.
1st greeting
2nd greeting
3rd greeting
4th greeting
...
Notice: each greeting is in a separate line and each line specifies whether this is the 1st, 2nd, ..
greeting
Important: avoid code repetition
Note: there is a separate line for each number from 1 to n (see output)

What is the Code in Java?
Sample output if n is 6:
1st greeting
2nd greeting
3rd greeting
4th greeting
5th greeting

Explanation / Answer
ManyGreetings.java
import java.util.Random;
public class ManyGreetings {
public static void main(String[] args) {
Random r = new Random();
String greeting = "greeting";
String temp= "";
int n = r.nextInt(500-5)+5;
for(int i=1; i<=n; i++){
if(i >=11 && i<=20){
temp = "th";
}
else{
if(i%10 == 1){
temp = "st";
}
else if(i%10 == 2){
temp = "nd";
}else if(i%10 == 3){
temp = "rd";
}else{
temp = "th";
}
}
System.out.println(i+temp+" "+greeting);
}
}
}
