if-else Statement
Lesson 3 of 11 in Coddy's Control Statements in Java course.
Before this lesson, we studied the "Simple If" statement, which meant to run a particular code if a condition is true. Now, what if I want to run a different code in both cases?
Example: If you are having a cold, you will have tea; otherwise, you will eat ice cream.
In Java, when you want to decide if this else that, then you use an if-else statement.
This statement evaluates the condition; if true, it executes one block of statements, and if false, it executes the else block of statements.
Syntax:
if(condition)
{
//code
}
else{
//code
}
Challenge
EasyWrite a function using if-else statement to accept the number and check if the number is even or odd.
Print the string accordingly as "Even" or "Odd".
Try it yourself
class IsEvenOdd {
public static String IsEvenOdd(int a1) {
// Write code here
}
