Chapter: Java Basics Last Updated: 26-08-2017 15:40:41 UTC

Program:

            /* ............... START ............... */
                
public class JavaPositiverNegative {

	public static void main(String[] args) {

		double number = 13.4;

		if (number < 0.0)
			System.out.println(number + " is a negative number.");

		else if (number > 0.0)
			System.out.println(number + " is a positive number.");

		else
			System.out.println(number + " is 0.");
	}

}

                /* ............... END ............... */
        

Output

13.4 is a positive number.

Notes:

  • In the above program, it is quite clear how variable number is checked to be positive or negative, by comparing it to 0.
  • If a number is greater than zero, it is a positive number.
  • If a number is less than zero, it is a negative number.
  • If a number equals to zero, it is zero.
