Chapter 5 Exercise 9, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

*5.9 (Find the two highest scores) Write a program that prompts the user to enter the number of students and each student’s name and score, and finally displays the student with the highest score and the student with the second-highest score.

import java.util.Scanner;
 
public class ProgrammingEx5_9 {
 
 public static void main(String[] args) {
  Scanner input = new Scanner(System.in);
  System.out.print("Enter the number of students:");
  int n = input.nextInt();
  int max = 0;
  int secondMax = 0;
  String maxName = "";
  String secondMaxName = "";
 
  for (int i = 0; i < n; i++) {
   System.out.print("Enter name and score of student (" + (i + 1)
     + "):");
   String name = input.next();
   int score = input.nextInt();
 
   if (score > max) {
    secondMax = max;
    //added secondMaxName = maxName; to correct the code. See comment in the post below 15.02.16
    secondMaxName = maxName; 
    max = score;
    maxName = name;
   } else if (score > secondMax) {
    secondMax = score;
    secondMaxName = name;
   }
 
  }
 
  System.out.println("The student with the highest score is " + maxName);
  System.out.println("The highest score is " + max);
  System.out.println("The student with the second highest score is "
    + secondMaxName);
  System.out.println("The second highest score is " + secondMax);
 
 }
}
