Java Programming for Complete Beginners - Java 16 - Step 04 - Java Arrays - Compare, Sort, and Fill

This video tutorial covers the basics of arrays in Java, including how to use the enhanced for loop for iteration, filling arrays with a specific value, comparing arrays for equality, and sorting arrays. The tutorial provides practical examples and explanations of these concepts, making it easier for learners to understand and apply them in their coding practices.

What is the main advantage of using an enhanced for loop over a traditional for loop?

• It automatically handles array length and index management.

• It is faster than a traditional for loop.

• It allows modifying array elements directly.

• It can iterate over multiple arrays simultaneously.

Which version of Java introduced the enhanced for loop?

• Java 7

• Java 5

• Java 4

• Java 6

What is the default value assigned to elements of a new integer array in Java?

• undefined

• 0

• null

• 1

How can you fill an entire array with a specific value?

• Using Arrays.replace

• Using Arrays.setAll

• Using Arrays.fill

• Using Arrays.copyOf

What does the Arrays.equals method return if two arrays have different lengths?

• Null

• False

• True

• An exception is thrown

Under what condition does Arrays.equals return true?

• When both arrays are sorted.

• When both arrays have the same length and elements.

• When both arrays are non-empty.

• When both arrays have at least one matching element.

Which method is used to sort an array in Java?

• Arrays.sort

• Arrays.arrange

• Arrays.order

• Arrays.sequence
