Java Exercises: Print mode values from a given a sequence of integers
Java Basic: Exercise-226 with Solution
Write a Java program to print mode values from a given a sequence of integers. The mode value is the element which occurs most frequently. If there are several mode values, print them in ascending order.
Input:
A sequence of integer’s ai (1 ≤ ai ≤ 100). The number of integers is less than or equals to 100.
Sample Solution:
Java Code:
import java.util.Scanner;
public class Main {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
int cnt[] = new int[100];
int i;
System.out.println("How many integers would you like to input(Max.100?)");
int x = input.nextInt();
System.out.println("Input the integers:");
for (i = 0; i <x; i++){
int n = input.nextInt();
cnt[--n]++;
}
int max = 0;
for (int n : cnt){
if (max < n){
max = n;
}
}
System.out.println("Mode value(s)in ascending order:");
for (i = 0; i < cnt.length; i++){
if (cnt[i] == max){
System.out.println(i + 1);
}
}
}
}
Sample Output:
How many integers would you like to input(Max.100?) 5 Input the integers: 25 35 15 5 45 Mode value(s)in ascending order: 5 15 25 35 45

Previous: Write a Java program to that reads a date (from 2004/1/1 to 2004/12/31) and prints the day of the date. Jan. 1, 2004, is Thursday. Note that 2004 is a leap year.
Next: Write a Java program which reads a text (only alphabetical characters and spaces.) and prints two words. The first one is the word which is arise most frequently in the text. The second one is the word which has the maximum number of letters.

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
