Pass-by-Value
• In a single virtual machine, the Java programming
language only passes arguments by value.
• When an object instance is passed as an argument to a
method, the value of the argument is a reference to the
object.
• The contents of the object can be changed in the called
method, but the original object reference is never
changed.
