Method overloading in java:
create more than one methods that have same name, but
different parameter lists and different definitions, within
a class.
It is used when objects are required to performed similar
tasks but with using different input parameter list.

class ABC
{
int x,y,z;
void star(int a,int b,int c)
{
x=a; y=b;z=c;
}
void star(int a,int b)
{
x=a; y= z=b;
}
void star(int a)
{
x= y= z= a;
}

int result()
{
return(x*y*z);
}
}
