Java Exercises: Find heights of the top three building in descending order from eight given buildings
Java Basic: Exercise-211 with Solution
Write a Java program to find heights of the top three building in descending order from eight given buildings.
Input:
0 ≤ height of building (integer) ≤ 10,000
Pictorial Presentation:

Sample Solution:
Java Code:
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int[] t = new int[8];
System.out.println("Input the heights of eight buildings:");
for(int i = 0; i < 8; i++){
t[i] = sc.nextInt();
}
Arrays.sort(t);
System.out.println("\nHeights of the top three buildings:");
for(int i = 7; i >= 5; i--){
System.out.println(t[i]);
}
}
}
Sample Output:
Input the heights of eight buildings: 25 19 23 45 18 23 24 19 Heights of the top three buildings: 45 25 24
