Check that if large number is divisible by 2

If a large number is divisible by 2, it means that the number can be evenly divided by 2 without leaving a remainder. In other words, the number is an even number.

To check whether a large number is divisible by 2, you can look at its last digit. If the last digit is even (i.e. 0, 2, 4, 6, or 8), then the number is divisible by 2. If the last digit is odd (i.e. 1, 3, 5, 7, or 9), then the number is not divisible by 2.

For example, if you have a large number like 123,456,789, you can check if it is divisible by 2 by looking at its last digit, which is 9. Since 9 is an odd number, the large number is not divisible by 2.

Program Solution

// Java program for

public class Divisibility
{
	public void isDivisibleBy2(String num)
	{
		// Condition
		// ➀ Last digit should be a Even number
		boolean result = false;
		int n = num.length();
		if (n == 1 && num.charAt(0) == '0')
		{
			// Given number is zero
			result = true;
		}
		else if (n > 0)
		{
			if (num.charAt(n - 1) == '0' 
                || num.charAt(n - 1) == '2' 
                || num.charAt(n - 1) == '4' 
                || num.charAt(n - 1) == '6' 
                || num.charAt(n - 1) == '8')
			{
				result = true;
			}
		}
		if (result == true)
		{
			System.out.print(" Given number (" + 
                             num + ") is divisible by 2\n");
		}
		else
		{
			System.out.print(" Given number (" + 
                             num + ") is not divisible by 2\n");
