The question is based on Roll number and Name of the class.So, We have to map both.
To implement this , We will use HashMap for mapping Integer and String.
By defining :  HashMap < Integer,String> hm = new HashMap< Integer,String>()
Steps:
* Input N for  number of Monk's colleagues.
* Add next N Roll Number(Integer) and name (String) in the HashMap hm.
* Input q queries .
* For each queries take the input int store in x.
* Print the value from the HashMap hm by using hm.get(x) .

Java8 Code:
```
import java.util.Scanner;
import java.util.HashMap;
import java.util.Map;
class May2020{
    public static void main(String args[] ) throws Exception {
        Scanner s = new Scanner(System.in);
        HashMap<Integer,String> hm = new HashMap<Integer,String>();
     
        int N = s.nextInt();
        for(int i=1;i<=N;i++){
            hm.put(s.nextInt(),s.next());
        }  
        int q = s.nextInt();
        while(q-- != 0){
            int x = s.nextInt();
            System.out.println(hm.get(x));   
        }
    }
}

```
