Question

The earth spins on its axis completing one rotation in a day. The earth revolves around the sun in 365 days to complete one revolution. What is the Java concept depicted in the given picture?

Options

• Array

• Condition

• Nested loop

• While loop

Answer 1

Nested loop

Explanation:

A nested loop is a loop inside another loop. The picture shows a 24-hour rotation repeating for each of the 365 days (inner 24-hour loop runs for every iteration of the outer 365-day loop), which matches the nested-loop concept in Java.

Example: for(int day=1; day<=365; day++) for(int hour=1; hour<=24; hour++) { … }.
