Answer Posted / amit singh

not the difference both are the string
String s = "hello"
its aliteral string it will be in a pool
imagine that when you cretae the anothre string
String s1 = "hello"
thn ther is not new Styrin object wil cretae its will pick
from the pool where the literal strin g hello will presnet
so s>
----------"hello"

s1>
both pointing the same string
2)String s = new String("hello");
there are two string will create frist the litreal "hello"
then the other through the new String("hello"); which is
point through referenece s is pointed so there is always
create a new String which is pointed by the reference s
its not going to pick through the pool
