Answer Posted / jo
generics is similar to templates in c++ language
by using generics we can delay the type creation
for example we want to swap to values by using swap method
like here int swap(int a=10,int b=5)
{
int temp;
temp=a;
a=b;
b=temp;
}
here we declare the type of variable a first where it is
declared and also we swap to string
swap(string s1="hi",string s2="bye")
{
sting =temp;
temp=s1;
s1=s2;
s2=temp;
}
where we write two methods for two diferent types but using
generics we can achve this simply
swap(<t>a ="hi"<t>b,="bye")
{
<t> temp;
temp=s1;
a=b;
b=temp;
}
