Lab Sesion-2
(Tf = Tc(9/5) + 32 , Tk = Tc + 273.15)
Program Code :
import java.util.Scanner;
public class Celsius_Fahrenheit {
public static void main(String[] args){
double celsius,fahrenheit,kelvin;
Scanner s = new Scanner(System.in);
System.out.println("Enter temperature in clesius :");
celsius = s.nextDouble();
fahrenheit = (celsius * 9/5) +32;
System.out.println("Temperature in Fahrenheit :"+fahrenheit);
kelvin = celsius + 273.15;
System.out.println("Temperature in Kelvin :"+kelvin);
}
}
OUTPUT :
2. Write a program that takes three numbers (integers) from the user and display the integers decreasing order. (User should give space separated input for three numbers (Ex. 5 15 10). User should not be asked three times to enter the number.)
Program Code :
import java.util.Scanner;
public class number {
public static void main(String[] args){
int x,y,z;
System.out.println("Enter three integers :");
Scanner m = new Scanner(System.in);
int a = m.nextInt();
int b = m.nextInt();
int c = m.nextInt();
if (a > b && a > c && b > c)
System.out.println( "Decreasing order =" +a + " " + b + " " + c);
else if ( b > a && b > c && a > c)
System.out.println( "Decreasing order =" +b + " " + a + " " + c);
else if ( c > b && c > a && b > a)
System.out.println( "Decreasing order =" +c + " " + b + " " + a);
else if ( a > c && a > b && c > b)
System.out.println( "Decreasing order =" +a + " " + c + " " + b);
else if ( b > c && b > a && c > a)
System.out.println( "Decreasing order =" +b + " " + c + " " + a);
else if ( c > a && c > b && a > b)
System.out.println( "Decreasing order =" +c + " " + a + " " + b);
}
}
OUTPUT :
3.Write a program that asks the user to enter a letter and check whether a letter is a vowel or constant.
Program Code:
import java.util.Scanner;
public class VowelOrConstant {
public static void main(String[] args){
System.out.println("Enter a character :");
Scanner s = new Scanner(System.in);
char ch = s.next().charAt(0);
if(ch=='a' || ch=='e' || ch=='i' || ch=='o' || ch=='u' || ch==' '){
System.out.println("Given character is a vowel");
}else{
System.out.println("Given character is constant");
}
}
}
OUTPUT :
4.Assume a vehicle plate number consists of three uppercase letters followed by four digits separated by ‘ - ’ (Ex. AGM-1326 ) . Write a program to generate ten plate numbers at a time. Output should display ten number plates in new lines.
Program Code:
import java.util.Random;
public class Plat {
public static void main(String[] args){
for(int i = 0; i<=10; i++){
int letter1 = 65 + (int)(Math.random() * (90 - 65));
int letter2 = 65 + (int)(Math.random() * (90 - 65));
int letter3 = 65 + (int)(Math.random() * (90 - 65));
//Generate four random digits.
int number1 = (int)(Math.random() * 10);
int number2 = (int)(Math.random() * 10);
int number3 = (int)(Math.random() * 10);
int number4 = (int)(Math.random() * 10);
//Display number plate
System.out.println("" + (char)(letter1) + ((char)(letter2))
+ ((char)(letter3)) + "-" + number1 + number2 + number3 + number4);
}
}
}
OUTPUT :
5.Java Program to Check Whether a Number is Even or Odd.
Program Code :
import java.util.Scanner;
public class EvenOdd {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
System.out.print("Enter a number: ");
int num = reader.nextInt();
if(num % 2 == 0)
System.out.println(num + " is even");
else
System.out.println(num + " is odd");
}
}
