Write statements that create the following arrays: a) \(A\) 100-clement int array referenced by the variable employeellumbers. b) \(A 25\) -clement double array referenced by the variable payRates. c) \(A\) 14-clement \(f\) loat array referenced by the variable miles. d) \(A 1000\) -clement char array referenced by the variable letters.

What would the valid subscript values be in a four-clement array of doubles?

What is the difference between an array's size declarator and a subscript?

What happens in Java when a program trics to use a subscript that is out-of bounds?

Write a statement that creates and initializes a double array with the following values: \(1.7,6.4,8.9,3.1,\) and \(9.2 .\) How many elements are in the array?

Look at the following statements: Int [1] numbers \(1=(1,3,6,9)\) Int \([1 \text { number } 32=\\{2,4,6,8)\) Int results Write a statement that multiplies element 0 of the nunbers1 array by clement 3 of the numbers 2 array and assigns the result to the result variable.

A program uses a variable named array that references an array of integers. You do not know the number of clements in the array. Write a for loop that stores -1 in cach element of the array.

Look at the following method header: public static vold mymethod (double[] array) Here is an array declaration: double[] numbers = new double [100] Write a statement that passes the numbers array to the myMethod method.

Write a method named zero, which accepts an int array as an argument and stores the value 0 in cach element.

a) Write a statement that declares a string array initialized with the following strings: "Mercury", "Venus", "Earth", and "Mars". b) Write a loop that displays the contents of cach element in the array you declared in A. c) Write a loop that displays the first character of the strings stored in cach element of the array you declared in A. (Hint: Use the string class's charat method discussed in Chaprer \(2 .\)
