Java Arrays

Given: Student [] students = new Student[25]

How would you access the instance variable, name, for the first student?

• String n = students.getName()

• String n = students[0].getName();

• Student s = students.getName();

• String n = students.getName(0);

Given String [] words = new String[20];

How many words are in the array?

• 19

• 20

Shifting array (called arr) elements to the right.... your for loop should start with:

• for (int i = arr.length -1;

• for (int i = 0;

• for (int i = arr.length;

• for (int i = arr.length();

Given String [] words = new String[don't know];

Which line of code gives you how many words are in the words array?

• words.length()

• words.length

Given String [] words = new String[don't know];

Which line of code gives you the length of the first word in the words array?

• words[0].length

• words[0].length()

When shifting elements of an array called arr, to the left, you should use:

• arr[i] = arr[i+1];

• arr[i] = array[i-1];

Given String [] words = {"cat", "kitten", "Lil Chef"}

What prints out ?

System.out.println(words[words.length - 1].indexOf("t");

• 0

• 1

• 2

• -1
