Expert Answer

 

Explanation::

  • Code in Java is provided below.
  • Read all the comments for better understanding of the code.
  • Each and every step is explained well in code itself.
  • Note class name is ReverseOrder.
  • Output is provided in form of screenshots.

Code in JAVA::

import java.util.Scanner;

public class ReverseOrder{

public static void main(String[] args){

/*

* To enter input from keyboard into standard input

* Scanner class is used.

*/

Scanner stdin=new Scanner(System.in);

/*

* An array of strings is declared below named

* lines[] of size 2000(You can change as per the requirement).

*/

String lines[]=new String[2000];

/*

* Integer index is used to keep count of number of lines

* entered by user.

*/

int index=0;

/*

* Now we scan lines and store them into

* array lines[].

* This while loop will terminate when user enters empty string

* i.e when s=””.

*/

System.out.println(“________Enter Lines_______”);

String s;

while(!(s=stdin.nextLine()).equals(“”)){

/*

* If user enter some string then that string

* is first stored in String variable named s.

*/

/*

* Now s is stored in array lines at current index

* Notice that after storing s at line[index],

* index is incremented.

*/

lines[index]=s;

index++;

}

/*

* Now to print lines in reverse order using

* standard output we run a for loop to traverse through

* Array lines[].

* We traverse in reverse order starting with index-1.

*/

System.out.println(“_________Reverse order lines_________”);

for(int i=index-1;i>=0;i–){

System.out.println(lines[i]);

}

}//main ends here

}//class ends here

Output::

Test case 1::

Test case 2:: (Here at start empty string is entered so no values are there in array lines to show)

Test Case 3::
