Write A Java Program To Test Whether A Number Is Positive Or Negative
In this java tutorial blog, we will write a Java Program to Check Whether a Number is Positive or Negative.
Write A Java Program To Test Whether A Number Is Positive Or Negative
Check if a Number is Positive or Negative using if else statement
public class PositiveNegativeTest {
public static void main(String[] args) {
double number = 11.2;
// true if number is less than 0
if (number < 0.0)
System.out.println(The number + " is a negative number.");
// true if the number is greater than 0
else if ( number > 0.0)
System.out.println(The number + " is a positive number.");
// if both test expression is evaluated to false
else
System.out.println(number +" is 0.");
}
}In the following example, we have taken a number from the user and will write a code to check if a number is positive or negative using the if-else statement.
public class CheckPositiveOrNegative
{
public static void main(String[] args)
{
int num;
Scanner sc = new Scanner(System.in);
System.out.print("Enter a number: ");
//reading a number from the user
num = sc.nextInt();
//checks if the number is greater than 0 or not
if(num>0)
{
System.out.println("The number is positive.");
}
//checks if the number is less than 0 or not
else if(num<0)
{
System.out.println("The number is negative.");
}
else
{
System.out.println("The number is zero.");
}
}
}
