(Array) How do you access a specific element?

T/F: Simple assignment of one array variable to another causes the data elements to be copied to a brand new array

False

T/F: The first index position in an array is 1.

False

T/F? A loop should continue until the array index variable is greater than the array's length.

False

True or false? In an array named "array1", consisting of 50 items, the last item in the array could be initialized to a value of 50 with the statement " array1[50]=50; "

False

True or false? Java allows the use of mixed data types within an array, which means item 1 in the array could be an int valued, while item 2 could be a char value.

False

arrayname.length

How do you find the length of an array?

index that doesn't exist

Index Out of Bounds Error

T/F: A method should accept an array parameter of any length

True

T/F: An Array named " table1 " that will hold 3 rows and 10 columns of data could be declared by the statement, int [] [] table1 = new int [3] [10]

True

T/F: Because an array is an object, it is possible for two variables to point to the same physical array

True

True or false? An array can be declared for any primitive data type, or for any reference data type

True
