Practice Programs using Functions

Today's Practice Programs are
These programs are Practice using a functions.
1.Age Category
program :
import java.util.Scanner;

public class Category {
static String isage(int num)
{
if(num>=50){
return "Your age is above 50";
} else if (num>=40 && num<=50) {
return "Your age is between 40 to 50";
}
else
return "Your age is less than 40";
}
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
System.out.println("Enter the age :");
int age=in.nextInt();
System.out.println(isage(age));

}

}

**
2.Adding two numbers**
program :
import java.util.Scanner;

public class big_two {
static boolean isgreater(int c, int d){
if(c>d){
return true;
}
return false;

}
public static void main(String[] args) {
    Scanner input=new Scanner(System.in);
    System.out.println("Enter two numbers :");
    int a=input.nextInt();
    int b=input.nextInt();
    if(isgreater(a,b)){
        System.out.println(a+" is greater");
    }
    else{
        System.out.println(b+" is greater");
    }

}

}

**3.Vowel or not
**program :
import java.util.Scanner;
public class vowel {
static boolean vowels(char b){
String s="aeiouAEIOU";
for (int i=0;i<s.length();i++) {
if (b == (s.charAt(i))) {
return true;
}

    }
    return false;
}
public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.println("Enter the Character : ");
    char a=input.next().charAt(0);
    if(vowels(a)){
        System.out.println(a+" is vowel");
    }
    else
        System.out.println(a+" is not a vowel");
}

}

4.Good Morning message
program :
import java.util.Scanner;

public class goodM {
static String isgood(int a){
if(a%3==0 && a%4==0){
return "Good Morning";
} else if (a%4==0) {
return "Good afternoon";
} else if (a%3==0) {
return "Good Evening";
}
else
return "Good Night";
}
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
System.out.println("Enter the number :");
int num=in.nextInt();
System.out.println(isgood(num));
}
}

**5.Season
**program :
import java.util.Scanner;

public class season {
static String ismonth(int m){
if(m>=3 && m<=5){
return "Spring Season";
} else if (m>=6 && m<=8) {
return "Summer Season";
} else if (m>=9 && m<=11) {
return "Autumn Season";
} else if (m==12 && m>=1 && m<=2) {
return "Winter Season";
}
else{
return "Invalid input";
}
}
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
System.out.println("Enter a month : ");
int month=in.nextInt();
System.out.println(ismonth(month));

    }
}
