/*
- Write a java program to define a thread for printing text on output screen for ‘n’
number of times. Create 3 threads and run them. Pass the text ‘n’ parameters to the
thread constructor.
Example:
i. First thread prints “COVID19” 10 times.
ii. Second thread prints “LOCKDOWN2020” 20 times
iii. Third thread prints “VACCINATED2021” 30 times
