Question

Write an if-else statement with multiple branches. If givenYear is 2100 or greater, print "Distant future" (without quotes). Else, if givenYear is 2000 or greater (2000-2099), print "21st century". Else, if givenYear is 1900 or greater (1900-1999), print "20th century". Else (1899 or earlier), print "Long ago". Do NOT end with newline.

mport java.util.Scanner;

public class YearChecker {

public static void main (String [] args) {

int givenYear = 0;

givenYear = 1776;
