public class Message {

 public static void main(String[] args) {

  Scanner input= new Scanner(System.in);

   System.out.println("Enter the year");

    int num=input.nextInt();

    if(num%4==0)

    System.out.println("This is leap year "+num);

    else

        System.out.println("This is not leap year "+num);

 }}

Output:

                      

java program that check number is even or odd

Problem 09:

  Scanner input= new Scanner(System.in);

   System.out.println("Enter five  number");

    int num=input.nextInt();

    if(num%2==0)

    System.out.println("The  number  "+num+" is even");

    else

        System.out.println("The  number  "+num+" is odd");

 }}

Output:

                         

java full important program find max and min number

Problem 08:

Write a program that take five number from user and find maximum number from it.

Discripition:

Declared  max and min assign the value of first number to max and min compare with all this number.

Solution:

import java.util.*;

public class Message {

 public static void main(String[] args) {

  Scanner input= new Scanner(System.in);

   System.out.println("Enter five  number");

    int num=input.nextInt();

    int num1=input.nextInt();

    int num2=input.nextInt();

    int num3=input.nextInt();

    int num4=input.nextInt();

    int max,min;

    max=min=num;

    if(max<num1)

        max=num1;

    if(max<num2)

        max=num2;

    if(max<num3)

        max=num3;

    if(max<num4)

        max=num4;

    if(min>num1)

        min=num1;

    if(min>num2)

        min=num2;

    if(min>num3)

        min=num3;

    if(min>num4)

        min=num4;

    System.out.println("The maximum number is "+max);

    System.out.println("The minimum number is "+min);

 }}

Output:

java program that check number is positive or negitive or zero

Problem 07:

Write a program that check number is positive negative or zero.

Discripition:

If number is greater then zero the number is positive if number is lessthen zero number is negative if number is equal to zero number is zero.

Solution:

import java.util.*;

public class Message {

 public static void main(String[] args) {

  Scanner input= new Scanner(System.in);

   System.out.println("Enter the  number");

    int num1=input.nextInt();

    if(num1>0)

         System.out.println("The number "+num1+" is positive");

   if(num1<0)

         System.out.println("The number "+num1+" is negitive");

   if(num1==0)

         System.out.println("The number "+num1+" is Zero");

 }}

Output:

jav aprogram find maximum number taking three number from user

Problem 06:

Write a program that take three numbers from user and find maximum number

Discripition:

First compare 1^st number with 2^nd  number then 1^st with 3^rd and then 2^nd with 3^rd

Solution:

import java.util.*;

public class Message {

 public static void main(String[] args) {

  Scanner input= new Scanner(System.in);

   System.out.println("Enter the frist  number");

    int num1=input.nextInt();

    System.out.println("Enter the Second  number");

    int num2=input.nextInt();

  System.out.println("Enter the Second  number");

    int num3=input.nextInt();

   if((num1>num2)&&(num1>num3))

        System.out.println("The maximum number is "+num1);

   if((num2>num1)&&(num2>num3))

        System.out.println("The maximum number is "+num2);

   if((num3>num2)&&(num3>num1))

         System.out.println("The maximum number is "+num3);

 }}
