Can you explain nested if-else statements in Java with examples?

Can you explain nested if-else statements in Java with examples?

Sure! Nested if-else statements are used when you want to check multiple conditions. Here's a simple example:

int number = 10;
if (number > 0) {
    System.out.println("Positive number");
    if (number % 2 == 0) {
        System.out.println("Even number");
    } else {
        System.out.println("Odd number");
    }
} else {
    System.out.println("Negative number");
}

What does this code do?

This code checks if the number is positive or negative. If it's positive, it further checks if it's even or odd.

Can you give me another example?

Of course! Here's another example:

int age = 20;
if (age >= 18) {
    System.out.println("Adult");
    if (age >= 65) {
        System.out.println("Senior citizen");
    } else {
        System.out.println("Not a senior citizen");
    }
} else {
    System.out.println("Minor");
}

What are the advantages of using nested if-else?

Nested if-else statements allow for more complex decision-making by enabling multiple conditions to be evaluated in a structured way.
