(Print distinct numbers) Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). (Hint: Read a number and store it to an array if it is new. If the number is already in the array, ignore it.) After the input, the array contains the distinct numbers. Here is the sample run of the program: Enter ten numbers: 1 2 3 2 1 6 3 4 5 2 The number of distinct number is 6 The distinct numbers are: 1 2 3 6 4 5

Answer 1

Program:

import java.io.*;
import java.util.Scanner;
class Distinctnumbers
{
public static void main(String[] args)
{
Scanner input=new Scanner (System.in); // Creating Scanner Object for user input
System.out.print("Enter ten Numbers: "); //prompt the user to enter 10 numbers
int[] values = new int[20]; //create an array to hold the numbers
int count = 0; //initalize count value to zero
for (int i=0; i<10; i++) //Here we are creating loop to find which numbers are distinct
{
int number = input.nextInt(); // Here we are taking input from the user
boolean distinct = true;
  
for (int j=0; j<count; j++)
{
if (number == values[j])
{
distinct = false;
break;
} // End of if
} // End of for loop
if (distinct) values[count++] = number;
} // End of for loop
System.out.print("The Distinct Numbers are: "); //print out "The Distinct Numbers are"
for (int i=0; i<count; i++) //Here we creating loop to print out each distinct number
{
System.out.print(values[i]+ " "); // Here each distinct number is seperated by space
}
} // End of main
} // End of class
