While Java Development Kit (JDK) 11 won’t access for addition month, assignment gain on its successor, JDK 12, with a about-face expressions adequacy lined up for the release, accepted in March 2019. Simplified coding is a ambition of this capability.
Switch expressions, which will be in beta accompaniment in JDK 12, extends the about-face account so it can be acclimated as either a account or an expression. This would accredit both forms to use either “traditional” or “ simplified” scoping and ascendancy breeze behavior. These changes would aftereffect in simplified “everyday” coding and adapt the way for use of arrangement analogous in switch.

As Java builders move to abutment arrangement matching, absolute irregularities of the absolute about-face account become impediments. These accommodate the absence ascendancy breeze behavior of about-face blocks; absence scoping of about-face blocks, in which the block is advised as one distinct scope; and about-face alive alone as a statement. The accepted architecture of Java’s about-face account follows carefully languages such as C and, by default, supports fallthrough semantics. This ascendancy breeze has been advantageous for autograph low-level code. But as about-face is acclimated in higher-level contexts, its error-prone attributes begins to outweigh flexibility.
JDK 12 is now in development in the OpenJDK community. For now, the about-face expressions angle is the alone technology formally listed as targetting JDK 12.
