Java Conditional Statement Exercises: Reads a floating-point number and print result
Java Conditional Statement: Exercise-28 with Solution
Write a Java program that reads a floating-point number. If the number is zero it prints "zero", otherwise, print "positive" or "negative". Add "small" if the absolute value of the number is less than 1, or "large" if it exceeds 1,000,000.
Test Data
Input a number: -2534

Sample Solution:
Java Code:
import java.util.Scanner;
public class Exercise28 {
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Input a number: ");
double n = in.nextDouble();
if (n > 0)
{
if (n < 1)
{
System.out.println("Positive small");
}
else if (n > 1000000)
{
System.out.println("Positive large");
}
else
{
System.out.println("Positive");
}
}
else if (n < 0)
{
if (Math.abs(n) < 1)
{
System.out.println("Negative small");
}
else if (Math.abs(n) > 1000000)
{
System.out.println("Negative large");
}
else
{
System.out.println("Negative");
}
}
else
{
System.out.println("Zero");
}
}
}
Sample Output:
Input a number: -2534 Negative
