Answer 1

Answer:

The required Java program is :-

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

 Scanner scan = new Scanner(System . in);

 System.out.print("Enter a number (Integer of decimal number) : ");

 double num = scan.nextDouble();

 scan.close();

 if(num > 0) {

     double squareNum = Math.pow(num,2);

     System.out.println("The number is greater than zero and its square is "+squareNum);

 }

 else {

     System.out.println("The number is less than or equal to zero.");

 }

   }

}

Note :-

The above códe is saved in a file named Main.java .

Also, condition in if statement can be changed and accordingly, the output statements will also change.
