Question 1 : Write a Java program to get a number from the user and print whether it is positive or negative.

Solution code : 
import java.util.*;
public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int x = sc.nextInt();
        if (x > 0) {
            System.out.println("x is greater than 0");
        } else {
            System.out.println("x is less than or equal 0");
        }
    }
}

Question 2 : Finish the following code so that it prints You have a fever if your temperature is above 100 and otherwise prints You don't have a fever.

public class Solution {
    public static void main(String[] args) {
        double temp = 103.5;
    }
}

Solution Code :
public class Solution{
    public static void main(String[] args) {
        double temp = 103.5;
        if (temp > 100) {
            System.out.println("You have a fever");
        } else {
            System.out.println("You don't have a fever");
        }
    }
}

Question 3 : Write a Java program to input week number(1-7) and print day of week name using switch case.

Solution Code :
import java.util.*;
public class Solution {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter week number(1-7): ");
        int week = sc.nextInt();
        switch(week) {
            case 1:
            System.out.println("Monday");
            break;
            case 2:
            System.out.println("Tuesday");
            break;
            case 3:
            System.out.println("Wednesday");
            break;
            case 4:
            System.out.println("Thursday");
            break;
            case 5:
            System.out.println("Friday");
            break;
            case 6:
            System.out.println("Saturday");
            break;
            case 7:
            System.out.println("Sunday");
            break;
            default:
            System.out.println("Invalid input! Please enter week number between1-7.");
        }
    }
}

Question 4 : What will be the value of x & y in the following program:

public class Solution {
    public static void main(String args[]) {
        int a = 63, b = 36;
        boolean x = (a < b ) ? true : false;
        int y= (a > b ) ? a : b;
    }
}

Solution :
Value of x = false & y = 63

Question 5 : Write a Java program that takes a year from the user and print whether that year is a leap year or not.

Solution Code :
import java.util.*;
public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("Input the year: ");
        int year = sc.nextInt();
        boolean x = (year % 4) == 0;
        boolean y = (year % 100) != 0;
        boolean z = ((year % 100 == 0) && (year % 400 == 0));
        if (x && (y || z)) {
            System.out.println(year + " is a leap year");
        } else {
            System.out.println(year + " is not a leap year");
        }
    }
}
