What is Generic in java? Where can we write Generic ( class or method or objects or etc...)? with simple example?
Thanks, Bose.
Answer Posted / vamsi
Generics can accept any datatype.
For example if the method write()takes integer type,but we
send them strings,is it possible for the mehod it takes
general variables,but it is possible using generics in java.
just use 'T' Synbol infront of ur method
eg- <T> write();
Not only for method it will be used in front ofclasses
<T>class gen{
int t1=1;
int t2=2;
String s1="generics"
String s2="example";
<T> write(<T> arg1,<T> arg2){
this.arg1=arg1;
this.arg2=arg2;
}
void display()
{
System.out.println(arg1+" "+arg2);
}
}
class example{
public static void main(String args[])
{
Gen g= new Gen();
g.display(t1,t2);
g.display(s1,s2);
}
}
Output is 1 2
Generics example
note# just i told u what i have known,if any thing is wrong
in this just tell me what is the corect way.
Thank u,
