Certificate.java

 

public class Certificate {

private String holder;

private int level;

 

public void setHolderAndLevel(String newHolder, int newLevel) {

holder = newHolder;

level = newLevel;

}

 

    public void print() {

        System.out.println("Certificate: " + holder + ", Level: " + level);

    }

}

 

-- SOLVE BELOW --

 

Certificates.java

 

import java.util.Scanner;

import java.util.ArrayList;

 

public class Certificates {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

ArrayList<Certificate> certificateList = new ArrayList<Certificate>();

Certificate currCertificate;

String currHolder;

int currLevel;

int certificateCount;

int i;

 

certificateCount = scnr.nextInt();

for (i = 0; i < certificateCount; ++i) {

currHolder = scnr.next();

currLevel = scnr.nextInt();

 

currCertificate = new Certificate();

currCertificate.setHolderAndLevel(currHolder, currLevel);

certificateList.add(currCertificate);

}

 

/* Your code goes here */

 

}

}

The program first reads integer certificateCount from input, representing the number of pairs of inputs to be read. Each pair has a string and an integer, representing the certificate's holder and level, respectively. One Certificate object is created for each pair and added to ArrayList certificateList. Call each Certificate object's print() method. Ex: If the input is: 3 Dax 6 Eve 7 Sue 13 then the output is: Certificate: Dax, Level: 6 Certificate: Eve, Level: 7 Certificate: Sue, Level: 13 Certificates.java Certificate.java
