Joshua J. Bloch (born August 28, 1961) is a software engineer, formerly employed at Google, and a technology author. He led the design and implementation of numerous Java platform features, including the Java Collections Framework, the java.math package, and the assert mechanism. He is the author of the programming guide Effective Java, which won the 2001 Jolt Award, and is a co-author of two other Java books, Java Puzzlers (2005) and Java Concurrency In Practice (2006).
Bloch holds a B.S. in computer science from Columbia University and a Ph.D. in computer science from Carnegie Mellon University. His 1990 thesis was titled A Practical Approach to Replication of Abstract Data Objects and was nominated for the ACM Distinguished Doctoral Dissertation Award.
Bloch has worked as a Senior Systems Designer at Transarc, and later as a Distinguished Engineer at Sun Microsystems. In June 2004 he left Sun and became Chief Java Architect at Google. On August 3, 2012, Bloch announced that he would be leaving Google.
In December 2004, Java Developer's Journal included Bloch in its list of the "Top 40 Software People in the World".
Bloch has proposed the extension of the Java programming language with two features: Concise Instance Creation Expressions (CICE) (coproposed with Bob Lee and Doug Lea) and Automatic Resource Management (ARM) blocks. The combination of CICE and ARM formed one of the three early proposals for adding support for closures to Java. ARM blocks were added to the language in JDK7, and Bloch remains active in the current discussions of proposals for closure support in Java.
Bloch's book Effective Java gives numerous tips on how to use Java effectively. Bloch mentions a huge number of terms and ideas, and typically defines and explains them, such as:
- static factory method - see factory (software concept)
- instance-controlled classes
- interface-based framework
- service interface
- provider registration API
- service access API
- service provider interface
- type inference
- telescoping constructor
- bounded wildcard type
- singleton pattern
- utility class
- default constructor
- immutable object
- object pool
- defensive copying
- obsolete reference
- unintentional object retention
- storage pool
- heap profiler
- bigram - pair of letters or characters
- code inspection
- type parameter
- generic type
- parameterized type
- actual type parameter
- migration compatibility
- unbounded wildcard type
- formal type parameter
- bounded type parameter
- recursive type bound
- type token
- raw type => "the name of the generic type used without any accompanying actual type parameters"
- unchecked warning
- generic method
- bounded wildcard
- class hierarchy
- tagged class
