How To accept the Values With Dynamically in Java

Q. Write a java program to accept the  two integer values and Multiply them dynamically . 

Program:-

class Mul
{
int a,b,c;
void accept(int p,int q)
{
a=p;
b=q;
}
void multiply()
{
c=a*b;
}
void display()
{
System.out.println("value of a ="+a);
System.out.println("value of b ="+b);
System.out.println("Multiply ="+c);
}
}
class MulDemo
{
public static void main(String k[])
{
if(k.length!=2)
{
Sysetm.out.println("Please Enter the 2 values");
}
else 
{
int x=Integer.parseInt(k[0]);
int x1=Integer.parseInt(k[1]);
Mul m= new Mul();
m.accept(x,x1);
m.multiply();
m.display();
}
}
}

Q. Write a java program to accept the  integer values and square them  dynamically .  

Program:-

class Square

{

int n,res;

void accept(int x)

{

n=x;

}

void calSquare()

{

res=n*n;

}

void display()

{

System.out.println("value of n="+n);

System.out.println("Square="+res);

}

}

class SquareDemo

{

public static void main(String k[])

{

if(k.length!=1)

{

System.out.println("Please Enter the one Value");

}

else

{

int x=Integer.parseInt(k[0]);

Square s=new Square();

s.accept(x);

s.calSquare();

s.display();

}

}

}

Q. Write a java program to accept the  two values and find the Area Of Triangle dynamically.
  

Program:-

class Triangle

{

float b,,h,res;

void accept(float x,float y)

{

b=x;

h=y;

}

void area()

{

res=0.5*b*h;

}

void display()

{

System.out.println("value of b="+b);

System.out.println("value of h="+h);

System.out.println("AreaOfTRaingle="+res);

}

}

class TraingleDemo

{

public static void main(String k[])

{

if(k.length!=2)

{

System.out.println("Please Enter the two Value");

}

else

{

float x1=Float.parseFloat(k[0]);

float x2=Float.parseFloat(k[1]);

Triangle t=new Triangle();

s.accept(x1,x2);

s.area();

s.display();

}

}

}

Q. Write a java program to accept the  two integer values and swapping them dynamically .  

program:- 

class Swap
{
int a,b,t,;
void accept(int p,int q)
{
a=p;
b=q;
}
void swapValues()
{
t=a;
a=b;
b=a;
}
void display()
{
System.out.println("values of a="+a);
System.out.println("values of b="+b);]
}
}
class SwapDemo
{
public static void main(String k[])
{
if (k.length!=2)
{
System.out.println("Please Enter Two values");
}
else
{
int x1=Integer.parseInt(k[0]);
int x2=Integer.parseInt(k[1]);
Swap s=new Swap();  //create an Object of swap class
s.accept(x1,x2);   //swaping of two values
s.swapValues();
s.display();
}
}
}

Output:-

cd/
cd blog data
javac SwapDemo.java
java SwapDemo 10 20

Q. Write a java program to accept two  values and find Big value with the  dynamically .

}
void findBig()
{
if(a==b)
{
System.out.println("Both values are same");
}
else
{
if (a>b)
{
System.out.println(a+" is greater than"+ b);
}
else
{
System.out.println(b+"is greater than"+a);
}
}
}
}

{
System.out.println("Please Enter the 2 values");
}
else
{
int x1=Integer.parseInt(k[0]);

Big b=new Big();
b.set(x1,x2);
b.findBig();
}
}
}

Program:-

class Biggest
{
int a,b,c;
void set(int x,int y,int z)
{
a=x;
b=y;
c=z;
}
void findBiggestValue()
{
if (a>0 && a>b && a>c)
{
System.out.println(a+" is bigger ");
}
if (b>0 && b>c && b>a)
{
System.out.println(b+" is bigger ");
}
if (c>0 && c>b && c>a)
{
System.out.println(c+" is bigger");
}
else
{
System.out.println("Both values are same");
}
}
}
