How to create array at run time according to user input value

In this problem we will learn how to create Array at run time . The program will asked user to enter the value of the array size which you want to create. After this the program will receive the values from the user.

Source Code

package com.ancodingpoint.www;

import java.util.Scanner;
public class Array_Size
{
 public static void main(String[] args)
 {
  Scanner input=new Scanner(System.in);
  int size;
  System.out.print("\nEnter Size of Array: ");
  size=input.nextInt();

  int[] myArray=new int[size];

  for(int i=0;i<size;i++)
  {
   System.out.print("Enter Value "+(i+1)+": ");
   myArray[i]=input.nextInt();
  }
  
  myArray=zeroMax(myArray,size);
  
  for(int i=0;i<size;i++)
  {
   System.out.print(myArray[i]+", ");
  }
 }

 public static int[] zeroMax(int[] myArray, int size)
 {
  for(int i=0;i<size;i++)
  {
   if(myArray[i]==0)
   {
    if((i+1)<size)
    {
     if(myArray[(i+1)]%2==0 && myArray[(i+1)]!=0)
     {
      myArray[i]=myArray[(i+1)]-1;
     }
     else if(myArray[(i+1)]%2==1)
     {
      myArray[i]=myArray[(i+1)];
     }
     else
     {
      myArray[i]=0;
     }
    }
   }
  }
  return myArray;
 }
}
