How do I add a >10, <100 clause to my program?-CodePudding

I am to enter 5 numbers, between 10 and 100. As each number is read, the program must display it only if it's not a duplicate of a number already read. I have to provide for the "worst case" in which all five numbers are different. I have use the smallest possible array to solve this problem and display the complete set of unique values input after the user enters each new value.

Problem I'm having is I don't know how to make it so that the number is between 10 and 100. Here's what I have so far. Thanks!

import java.util.Scanner; import java.util.Arrays;

public class IsDuplicate {

public static void main(String[] args) {
Scanner input = new Scanner (System.in);
int array[] = new int [5];
int size = 0; 
int x;



for (int i = 0; i < 5; i  ) {
    System.out.print("Enter an integer between 10 and 100: ");
    x = input.nextInt();
 
    
    if(size == 0 || newNumber(array, size, x)) {
        System.out.println("This is the first time "  x  " has been entered.");
        array[size] = x;
        size  ;
    }
    
}


System.out.println("The complete set of unique values entered is: ");
    for (int i = 0; i<size; i  ) {
        System.out.println("Unique value"  (i 1)  ": is "  array[i]);
    }
    
    
    
    
}

private static boolean newNumber(int y[], int size, int x) {
    for (int i = 0; i <size; i  ) {
        if (y[i] == x) {
            return false;
        }
    }
    return true;
}

}

CodePudding user response：

You can implement this quite easily. All you have to do is adjust your for loop taking the inputs, and add in a check for the value of x to see if it is !(x < 10) && !(x > 100).

If your program is supposed to ask for another number when an unacceptable value has been entered, then you will also need to subtract 1 from i to ensure you still get 5 numbers total.

if(size == 0 || newNumber(array, size, x) ) {
       if(!(x < 10) && !(x > 100))
       {
        System.out.println("This is the first time "  x  " has been entered.");
        array[size] = x;
        size  ;
       }
       else
       {
           System.out.println("The number you entered is outside the range of acceptable values.");
           i = i - 1;
       }
    }
