1. Basic Comparison

If-Else

The if-else construct evaluates conditions sequentially. It’s versatile and supports complex conditions but can become verbose when handling many cases.

Example:

int day = 2;
String dayName;
if (day == 1) {
    dayName = "Monday";
} else if (day == 2) {
    dayName = "Tuesday";
} else if (day == 3) {
    dayName = "Wednesday";
} else {
    dayName = "Invalid day";
}
System.out.println(dayName);
