LAB 1A: Program to check x and y values using if statement and displaying message whether x is greater than y

package LabPgm1;

public class Pgm1 
{
	public static void main(String args[])
	{
		int x=8, y=3;
		
		System.out.println("X = " +x);
		System.out.println("Y = " +y);
		
		if( x > y )
			System.out.println("X is greater than Y");
		else
			System.out.println("Y is greater than X");
	}

}



OUTPUT:

X = 8
Y = 3
X is greater than Y






LAB 2A: Program to list the factorial of the numbers from 1 to 10 using while loop

package LabPgm2;

public class Pgm2 
{
	public static void main(String[] args) {
		int fact, i, j;
		
		for(i=1;i<=10;i++)
		{
			System.out.print("\nFactorial of " + i + " is: ");
			fact=1;
			j=1;	
			while(j<=i)
			{
				fact = fact * j;
				j++;
			}
			System.out.print(fact);
		}

	}

}











OUTPUT:

Factorial of 1 is: 1
Factorial of 2 is: 2
Factorial of 3 is: 6
Factorial of 4 is: 24
Factorial of 5 is: 120
Factorial of 6 is: 720

Factorial of 8 is: 40320
Factorial of 9 is: 362880
Factorial of 10 is: 3628800






















LAB 3A: Program to find the area and circumference of the circle by accepting the radius from the user

package LabPgm3;
import java.util.*;

public class Pgm3 
{
	public static void main(String args[])
	{
		double radius, area, circum;
		Scanner in = new Scanner(System.in);
		
		System.out.println("Enter radius value: ");
		radius = in.nextDouble();
		
		area=Math.PI * radius * radius;
		circum = 2 * Math.PI * radius;
		
		System.out.println("Area = " +area);
		System.out.println("Circumference = " +circum);
	}

}

OUTPUT:

Enter radius value: 
2.6
Area = 21.237166338267002
Circumference = 16.336281798666924

package LabPgm4;

public class AddDemo 
{
	int a=2, b=6, res;
	double c=3.5, d=5.6, res1;
	void addInt()
	{
		res = a+b;
		System.out.println("Addition of default Integer values" +a+ " and  " +b+ " is: " + res);
	}
	void addInt(int x, int y)
	{

		res1 = c+d;
		System.out.println("Addition of Float parameters values "+c+" and "+d+" is: " +res1);
	}

}

package LabPgm4;

public class Pgm4 
{
	public static void main(String[] args) 
{
		AddDemo ad = new AddDemo();
		Scanner in = new Scanner(System.in);
		
		int a,b;
		double c,d;
		
		System.out.println("Enter 2 integer values" );
		a=in.nextInt();
		b=in.nextInt();	
		
		System.out.println("Enter 2 float values" );
		c=in.nextDouble();
		d=in.nextDouble();	
		
		ad.addInt();
		ad.addInt(a,b);
		ad.addFloat();
		ad.addFloat(c,d);

	}

}








OUTPUT:

Enter 2 integer values
3
6
Enter 2 float values
2.3
6.5

Addition of default Integer values 2 and 6 is: 8
Addition of Integer parameters values 3 and 6 is: 9

Addition of default Float values 3.5 and 5.6 is: 9.1
Addition of Float parameters values 2.3 and 6.5 is: 8.8

	int add, sub;
	Scanner in = new Scanner(System.in); 
	void getdata()
	{
		System.out.println("Enter a value:");
		a= in.nextInt();
		System.out.println("Enter b value:");
		b= in.nextInt();
	}
	void add1()
	{
		add = a + b;
		System.out.println("Addition: "+add);
	}
	void sub1()

	}
	void div1()
	{
		div = a / b;
		System.out.println("Division: "+div);
	}
}

package LabPgm5;
