IN JAVA - Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline.
Ex: If the input is:
-15 10
the output is:
-15 -10 -5 0 5 10
Ex: If the second integer is less than the first as in:
20 5
the output is:
Second integer can't be less than the first.
For coding simplicity, output a space after every integer, including the last.
BASE CODE:
import java.util.Scanner;
public class LabProgram { public static void main(String[] args) { /* Type your code here. */ }}
