Ideas in this flowchart

String variables can be declared, assigned, and reassigned.
String variables receive values using the regular assignment operator.
Initial string assignments
String firstName = "Thomas";
String lastName = "Waits";
A variable can be assigned a new string value.
firstName = "Tom";
Reassignment does not change the original string.
The variable firstName points to a new string.
If no other references point to the old string
The old string becomes eligible for garbage collection.
The JVM takes care of garbage collection.

"We can declare String variables and assign them values using the regular assignment operator.\n\n1 String firstName = \"Thomas\";\n\n2 String lastName = \"Waits\";\n\n3 4 //we can also reassign values\n\n5 firstName = \"Tom\";\n\nNote that the reassignment in the last line in the example does not change the original string. It just makes the variable firstName point to a new string. If there are no other references to the old string, it becomes eligible for garbage collection and the JVM takes care of it."
