Main articles: Java (software platform) and Java virtual machine One design goal of Java is portability, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate run time support. In addition to language differences, porting may also require data conversion and adaptation to new system procedures for running an application. The recently released Java TM 2 SDK, Standard Edition Version 1.4.0 contains a number of new features.

(In practice, there are library bugs that diminish this to "write once, debug anywhere.") One example includes testing of a product which is well functioning in Windows 7 and measuring its behaviour in Windows 8. Each of the preceding buzzwords is explained in The Java Language Environment, a white paper written by James Gosling and Henry McGilton. Java threads have also been advertised as scaling well on multi-CPU machines. Mobile number portability (MNP) is a service that allows a cellphone or smartphone customer to change telecom carrier and keep the same phone number. However, advances in compiler and virtual machine technologies are bringing performance close to that of native code without threatening portability. In versions up to and including Java 8, a String was composed of an immutable array of Unicode characters. Portability of the estate tax exemption between spouses is in effect, so when Sue dies: $18 million estate less $23.16 million in two estate tax exemptions = $0 taxable estate; Bob's estate won't have to use any of his estate tax exemption because all their assets are jointly titled and they pass directly to Sue by right of survivorship.
