Answer 1

Required Answer:-

Question:

• Write a program in Java to input a number and check if the entered number is positive or negative.

Solution:

Here comes the códe.

import java.util.*;

public class Number {

 public static void main(String[] args) {

    int n;

    Scanner sc=new Scanner(System.in);

    System.out.print("Enter an integer: ");

    n=sc.nextInt();

    if(n>0)

      System.out.println("Number is positive.");

    else if(n<0)

      System.out.println("Number is negative.");

    else

      System.out.println("Its zero.");

    sc.close();

 }

}

Logic:

1. Take the number as input.
2. Check if the number is greater than 0. If true, the number is positive. If not true, check if the number is less than 0 or not. If true, the number is negative or else, the number is zero.
