Question
**Java Program to Check Numbers Near Multiples of 10**

Write a Java program to print `true` if the user entered a non-negative number that is 1 or 2 less than a multiple of 10. For example, 18 and 19 should return `true`, but 20 should return `false`.

In this program, we want to determine whether a given number falls within this condition. The logic involves checking if a number modulo 10 is either 8 or 9 (since these positions would be 1 or 2 less than the next multiple of 10). 

Example:
- For 18: `18 % 10 = 8`, which meets the condition, so the program prints `true`.
- For 19: `19 % 10 = 9`, which meets the condition, so the program prints `true`.
- For 20: `20 % 10 = 0`, which does not meet the condition, so the program prints `false`.

This program can help illustrate condition checking and the use of the modulo operator in Java.
