Question

in Java, I need to create an array of animals. The user is going to be prompted to enter the size of the array where a valid size is 10-30(inclusive). Then I have to populate only half of this array. I am not sure how to do that so can you please write comments explaining.

Thank you

Answer 1

An array of animals is created keeping in mind it will consists of the name of the animals . so it is declared as a string.

As question states the code is below. It is self explanatory with comments and output.

CODE:

/* package whatever; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Check
{
   public static void main (String[] args) throws java.lang.Exception
   {
       // your code goes here
       int i;
       //This reads the input provided by user using keyboard
       Scanner scan = new Scanner(System.in);
       //prints the statement which asks user to enter size of array
System.out.print("Enter the size of array animals (10-30): ");

// This method reads the number provided using keyboard
int n = scan.nextInt();
//create an array of string data type with size as defined by the user
String[] animals = new String[n];
//traversing the array from 0 index to half to what user has entered
for(i=0;i<n/2;i++){
   //populating half the array with string "abc"
   animals[i]="abc";
}
for(i=0;i<n;i++){
   //display all the elemnts of the array
   System.out.println("entered:"+animals[i]);
}
   }
}

INPUT:

10

OUTPUT:

entered:abc
entered:abc
entered:abc
entered:abc
entered:abc
entered:null
entered:null
entered:null
entered:null
entered:null
