What are if-else statements in Java?

Can you explain what if-else statements are in Java?

Sure! If-else statements are used for decision-making in Java. They allow you to execute different blocks of code based on certain conditions.

How do I write an if-else statement in Java?

You can write it like this:

if (condition) {
    // code to execute if condition is true
} else {
    // code to execute if condition is false
}

Can you give me an example?

Of course! Here's a simple example:

int number = 10;
if (number > 0) {
    System.out.println("Positive number");
} else {
    System.out.println("Not a positive number");
}

What if I want to check multiple conditions?

You can use else if to check multiple conditions. For example:

if (number > 0) {
    System.out.println("Positive number");
} else if (number < 0) {
    System.out.println("Negative number");
} else {
    System.out.println("Zero");
}
