Do we have always use string pattern =new String(data) in java or I can use string pattern= value? in general, do we use always string str= new string or string str=value;

for example,

1. In the body of the main method, declare a single String class type variable named pattern.

The pattern will hold the address of a String object with a string literal as its value, which is needed to be created in problem 4.
