String class:1. for the Equality judgment of a string object, use the Equals () method instead of = =. The Equals () of string determines whether the current string is consistent with the contents of the passed-in string.2. string is a constant, and its object cannot be changed once it has been created. When using the + stitching string, a new string object is generated instead of appending content to the original string object.3. string pool is in stack memory.4. String s = "
