Problem
This problem envolves you seeing if two hard coded arrays are equal. You should use two int arrays to equate. Even though your arrays are hard coded into your program, you should not assume to know the length of the arrays. In other words use: array.length Remember that your arrays start indexing at 0 and that you should watch out for loops indexing arrays out of bounds. These are the most common pitfalls with a problem like this. If you can try to structure your code so that your loop is only comparing to the length of one of the arrays and not both of them.

Solution Code
public class ArrayEquate
{
public static void main (String[]args)
{
int[] array1 = {1,2,3,4,5,6,7,8,9,10}; //First array to be equated
int[] array2 = {1,2,3,4,5,6,7,8,9,0}; //Second array to be equated
boolean equal = true; //boolean to say whether the arrays are equal or not.
//Check to see if the arrays are equal in lenght, if they are not the arrays can not be equal.
if (array1.length == array2.length)
{
//Use a for loop to iterate through the arrays, comparing their values.
for (int i = 0; i < array1.length; i++)
{
//If there is a mismatch, they are not equal.
if (array1[i] != array2[i])
equal = false;
}
}
else
equal = false;
//Print out the status of the arrays to the console.
if (equal)
System.out.println ("The two arrays are equal.");
else
System.out.println ("The two arrays are not equal.");
}
}
