Question

Write a for loop to populate array userGuesses with NUM_GUESSES integers. Read integers using Scanner. Ex: If NUM_GUESSES is 3 and user enters 9 5 2, then userGuesses is {9, 5, 2}.

Answer 1

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num12 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter Number of guesses");

       int NUM_GUESSES = in.nextInt();

       int [] userGuesses = new int[NUM_GUESSES];

       for(int i =0; i<userGuesses.length; i++){

           System.out.println("Enter each value");

           userGuesses[i]= in.nextInt();

       }

       System.out.println("userGuesses is "+ Arrays.toString(userGuesses));

   }

}

Explanation:

• Prompt user to enter a value for the length of the array int NUM_GUESSES = in.nextInt();
• Create an array of int int [] userGuesses = new int[NUM_GUESSES];
• Use a for loop to request and add elements to the array
• print the array using Arrays.toString () method
