In this tutorial, we will learn about else-if statements in Java. We will cover the basics of conditional execution using if-else-if statements.
An else-if statement is a conditional statement that allows multiple conditions to be tested sequentially. It provides a way to execute different code blocks based on different conditions.
The syntax for the else-if statement in Java is:
if (condition1) {
// Code block to execute if condition1 is true
} else if (condition2) {
// Code block to execute if condition2 is true
} else {
// Code block to execute if none of the conditions are true
}
The else-if statement evaluates the specified conditions in order. The first condition that is true will have its code block executed; if none of the conditions are true, the code block inside the else statement is executed.
num
.num
.num
is positive, negative, or zero.num
is positive, negative, or zero.public class Main {
public static void main(String[] args) {
int num = -5;
if (num > 0) {
System.out.println(num + " is positive.");
} else if (num < 0) {
System.out.println(num + " is negative.");
} else {
System.out.println(num + " is zero.");
}
}
}
-5 is negative.

if (marks >= 90) {
System.out.println("Grade: A");
} else if (marks >= 80) {
System.out.println("Grade: B");
} else if (marks >= 70) {
System.out.println("Grade: C");
} else if (marks >= 60) {
System.out.println("Grade: D");
} else {
System.out.println("Grade: F");

Grade: B

.public class Main {
public static void main(String[] args) {
float temperature = 75.5f;
if (temperature > 100) {
System.out.println("It's extremely hot.");
} else if (temperature > 85) {
System.out.println("It's hot.");
} else if (temperature > 60) {
System.out.println("It's warm.");
} else if (temperature > 32) {
System.out.println("It's cold.");
} else {
System.out.println("It's freezing.");
}
}
}
It's warm.
