Video Objective
What are you going to learn ………….
What is the logic of decision program?
What are the language construct in Java for making decision program?
Write a Java program to check where a number is even or odd?
Practical live demo on the above program in Java.
What is the logic of decision based problem?
“A problem has multiple optional outputs and create a confusion for deciding the appropriate output.”
Ex.
Check even or odd.
Here,
Output = even / odd
But a number can never even and odd both.
So, we need to decide when the number is even or odd.
As, we know ……
Case 1 : a number is even when it is divisible by 2.
Case 2 : a number is odd when it is not divisible by 2.

Ladder of ‘if’ and ‘else’

WAJP to check where a number is even or odd?
Import java.util.*;
class A
{
public static void main(String st[])
{
int n,r;
Scanner input=new Scanner(System.in);
System.out.println(“Enter a number : ”);
n=input.nextInt();
r=n%2;
if(r==0)
{
System.out.println(“Even Number”);
}
else
{
System.out.println(“Odd Number”);
}
}
}
