Why String str="hello" and String str = new String("hello") are different?

when we compare both by comparison operator it will give false as result

Looks like Java. basically new string just creates a new value on a heap. comparison checks for reference equality, so it will return false for that code. Actually even if you don't use new to allocate a memory it still might do it by itself (depending on some things)
