Question

I am new to java i got error in HashMap this is what i tried

Hashmap h=new HashMap();
h.put(1,"java");
h.put(2,"c");

but got error

Answer 1

use DataTypes Also Like this is the older procedure to store the values in hashmap

HashMap<Integer,String> h=new HashMap<Integer,String>();
h.put(1,"java");
h.put(2,"c");

It will Work

Answer 2

For better quality code and low coupling you should use MAP.

Map<Integer,String> h= new HashMap<>();
            h.put(1,"java");
            h.put(2,"c");
