Exercise - 4
a) Constructor Overloading
AIM: To write a JAVA program to implement constructor overloading
SOURCE-CODE:
class A
{
int l,b;
A()
{
l=10;
b=20;
}
A(int u,int v)
{
l=u;
b=v;
}
int area()
{
return l*b;
}
}
class overconstructdemo
{
public static void main(String args[])
{
A a1=new A();
int r1=a1.area();
System.out.println("The area is: "+r1);
A a2=new A(30,40);
int r2=a2.area();
System.out.println("The area is: "+r2);
}
}
OUT-PUT:
The area is: 200
The area is: 1200
b) Method Overloading
AIM: To write a JAVA program implement method overloading
SOURCE-CODE:
class A
{
int l=10,b=20;
int area()
{
return l*b;
}
int area(int l,int b)
{
return l*b;
}
}
class overmethoddemo
{
public static void main(String args[])
{
A a1=new A();
int r1=a1.area();
System.out.println("The area is: "+r1);
int r2=a1.area(5,20);
System.out.println("The area is: "+r2);
}
}
OUT-PUT:
The area is: 200
The area is: 100
