REST API Automation Testing from Scratch - REST Assured Java - Introduction to Arrays

The video tutorial introduces arrays in Java, explaining their purpose as containers for multiple values of the same data type. It covers defining arrays, allocating memory, initializing values, and retrieving values using loops. The tutorial provides examples and emphasizes the importance of understanding array indices and memory allocation.

What is an array in Java?

• A container that stores multiple values of the same data type

• A method to define a single integer

• A container that stores multiple values of different data types

• A single variable that holds one value

How do you declare an array to store 5 integer values?

• int a[] = {5};

• int a = 5;

• int[] a = new int[5];

What keyword is used to allocate memory for an array in Java?

• allocate

• new

• create

• memory

What is the starting index of an array in Java?

• 10

• 5

• 0

• 1

How do you assign a value to the third position in an array named 'a'?

• a[3] = value;

• a[0] = value;

• a[2] = value;

• a[1] = value;

Which method is used to find the size of an array?

• arraySize()

• size()

• length()

• getSize()

What will be the output of the loop that prints all elements of the array 'a' initialized with values {2, 6, 1, 9, 12}?

• 6 2 9 1 12

• 1 2 6 9 12

• 12 9 1 6 2
