Hello Friend,

Differences:

1)String str=new string("abc") creates two objects, one in heap memory and one in string pool.It utilize memory in a better way with fulfilling object creation. While String st="abc" creates one object which goes to string pool.It consumes less memory.

2)String str = abc is a String literal where as String str = new String("abc") is a String Object.

Thanks
