Java Fundamentals Review for string objects, you can use the "=" assignment, or you can use the New keyword to assign a value, what is the difference between the two ways?

The string type is a type that is often used in the actual work, divided from the data type, string is a reference type, and is a class defined in the API. So objects of type string can be created with new, such as String Name=new string ("string"), assigned to the variable name, the value "string", but the string analogy to other classes is somewhat special, you can use ' = ' to directly assign values, such as String Name= "string", which is also assigned to the variable name, the value "string", the two assignments are different, using new assignment, always creates a new object, initializes the value of the string in the new memory space, and uses "=" To assign the value, Instead of initializing a new string each time, it looks for a string from a "string instance pool" with no strings to be assigned, if there is a direct reference, if it does not exist, initializes a string and puts it into the string instance pool. In practical programming, "=" is often used to assign a value to a variable of type string.
