What is the correct way to initialize an array with 10 positions?

• int numbers = new int[10];
• int[] numbers = new int[];
• int[10] numbers = new int[10];
• int[] numbers = new int[10];

What value is stored in each of the 5 positions in this array? (What is the default value provided by Java).
int[] numbers = new int[5];

• null
• 1
• 0
• nothing

What value is at index 1 in this array?  String[] names = {"Mack", "Dennis", "Dee", "Charlie"};

What is the correct way to create an array with these three numbers: 12  8  15

• int[] = {12, 8, 15};
• int[] nums = {12  8  15};
• int[] nums = {12, 8, 15}
• int[] nums = {12, 8, 15};

True or False:  An array can be store different types of data (like store both doubles and ints).

• True
• False
