Array Explanation

Here's some random things that I know about arrays.

An array is a "list" or groups of values, and can be in any type of value. [0] is the first index.

There are int[], String[], boolean[] arrays and many more.

You can declare a array in two ways:

int[] testArray;
or
int testArray[] = new int[5];

The second way will create an array with 5 empty values. You must declare an amount of values. the array cannot change size after it has been created.

testArray.length; // the length of the array

You can change a value using testArrat[n] where n is the index of the value you wish to change;

testArray[2] will return 6, for example.
testArray[2] = 4; it will now return 4.

You can't just print an array. However, you can iterate through an array like this:

for (int i: testArray) {
   System.out.println(i); // this will print every value inside of testArray on a new line.
}

To compare values, you would still abide by the normal procedures. If you have a String[] array, you'd use .equals, and == for mostly anything else.

These are some more topics that should have been learned:

• To use arrays to store data in and retrieve data from lists and tables of values. 

To store, you'd put testArray[0] = 1; and to retrieve you'd put int variable = testArray[0].

• Pass arrays to methods. 

To do this, you'd create a method that takes in an array. You can return arrays too, but you can't print them.

I made the Pig Latin one able to be converted with sentences or words, and it also checks to make sure there's only letters inputted.

All of the pig latin "rules" are followed.
