Write program in java without using public static void travelToFuture
Objective: To build a time-traveling program that allows users to travel forward or backward in time in fixed intervals.
Problem statement: You are to create a "Time Machine" simulator. Users can select if they want to travel into the future or the past, and then specify the number of years they want to travel.
Requirements:
Use a for loop to count the years as they pass by
Provide an engaging narrative for the time-travel experience(describe what the world looks like in different eras).
Sample output:
Welcome to the Time Machine!
Would you like to travel to the future or the past? (Enter 'future' or 'past'): future
How many years would you like to travel into the future? 3
Traveling to the future...
Year 1: Electric cars are now the standard.
Year 2: AI-powered robots are common in households.
Year 3: Space tourism has become affordable.
Welcome to the year 2026! Enjoy your stay!
