Review: Conditionals

In Java, conditional statements are used to execute different blocks of code based on certain conditions. The most commonly used conditional statement is the `if/else` statement. An `if` statement is used to execute a block of code if a certain condition is `true`. An `else` statement is used to execute a block of code if the preceding `if` statement condition is `false`. `If/else` statements can be used to make decisions based on input from the user, the current state of the program, or any other logical conditions that need to be evaluated. The **conditional statements** that are provided in Java are: - `if` - `if/else` - `if/else if/else` - `switch` **Review: Example** - int num = 7; if (num % 2 == 0){ System.out.println(num + " is even."); } else { System.out.println(num + " is odd."); } //Output: "7 is odd." In the example above, an integer variable named `num` is assigned the value of `7`. It then checks if the remainder of `num` divided by `2` is equal to `0` using the modulo operator `%`. If the remainder is `0`, then it means that the number is even, and the code prints out a message saying so. Otherwise, if the remainder is not equal to `0`, then it means that the number is odd, and the code prints out a different message saying so. In this case, since `7` is not divisible by `2` without a remainder, the output will be `"7 is odd."`.
