How to append to an array in java

23.1 Append to Oversize Array

Java Help

Given an oversize array with size1 elements and a second oversize array with size2 elements, write a method that returns the first array with the elements of the second appended to the end. If the capacity of the oversize array is not large enough to append all of the elements, append as many as will fit.

Hint: Do not construct a new array. Instead, modify the contents of the oversize array inside the method.

Code//

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

public class AppendOversize
{

public static void main(String[] args)
{
// Do not edit this method
Scanner keyboard = new Scanner(System.in);
final int SIZE = 20;
int[] array = new int[SIZE];
int[] append = new int[SIZE];

// Read in the first array
int value = keyboard.nextInt(); // priming read
int index;
for(index=0; index {
array[index] = value;
value = keyboard.nextInt(); // priming read
}
keyboard.nextLine(); // get the carriage return out of there

// Get the size from the number of values put in the first array
int arraySize = index;

// Read in the second array
value = keyboard.nextInt(); // priming read
for (index=0; index {
append[index] = value;
value = keyboard.nextInt(); // priming read
}
int appendSize = index;

arraySize = appendOversize(array, arraySize, append, appendSize);
System.out.println("Array is " + Arrays.toString(array) + " size is " + arraySize);
keyboard.close();
}

public static int appendOversize(int[] array, int size, int[] toAppend, int toAppendSize)
{

// Put your code here

return 0; // edit this line
