Answer:
The program to this question in java can be given as
import java.util.Scanner;
//import package for take input from user.
public class Main //define class
{
public static void main(String[] args) // main function
{
Scanner input = new Scanner(System.in);
System.out.println("Enter a number:");
int givenYear=input.nextInt();
//if condition true output is "Distant future" (without quotes).
if (givenYear >= 2100)
{
System.out.print("Distant future");
}
// else if condition(2000-2099) true output is "21st century".
else if((givenYear >= 2000) && (givenYear <= 2099))
{
System.out.print( "21st century");
}
//else if condition (1900-1999) true output is "20th century".
else if((givenYear >= 1900) && (givenYear <= 1999)){
System.out.print( "20st century");
}
//else condition false output is "Long ago".
else{
System.out.print( "Long ago");
}
}
}
Explanation:
In this program we use the scanner class. Scanner class is used to take input from the user.When the user input the input the year. It hold on a variable(givenYear) that is integer type.Then we check the value between the ranges that is given in question.To check all the condition we use the if-elseif-else statement, and AND(&&) operator.AND operator is a logical operator that is used for compare two values together. The output of the program can be given as:
Output:
Enter a number: 2016
21st century
