This answer is an attempt to address: how to control java version system-wide (not just in currently running shell) when several versions of JDK are installed for development purposes on macOS El Capitan or newer (Sierra, High Sierra, Mojave). Press Y to save your changes source ~/.zshrc zshrc file should work: nano ~/.zshrcĮxport JAVA_HOME=$(/usr/libexec/java_home -v 1.8.0)

Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)Īdd the export JAVA_HOME… line to your shell’s init file.įor Bash (as stated by antonyh): export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)įor Fish (as stated by ormurin) set -x JAVA_HOME (/usr/libexec/java_home -d64 -v1.8)

Now when you run java -version you will see: java version '1.6.0_65' Or you can specify just the major version, like: export JAVA_HOME=`/usr/libexec/java_home -v 1.8` Pick the version you want to be the default ( 1.6.0_65-b14-462 for arguments sake) then: export JAVA_HOME=`/usr/libexec/java_home -v 1.6.0_65-b14-462` Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home In this tutorial, we will install the latest JDK version which is 12.0.1.First run /usr/libexec/java_home -V which will output something like the following: Matching Java Virtual Machines (3):ġ.8.0_05, x86_64: 'Java SE 8' /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Homeġ.6.0_65-b14-462, x86_64: 'Java SE 6' /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Homeġ.6.0_65-b14-462, i386: 'Java SE 6' /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home Different JDK versions may have some incompatibilities between different versions. Before downloading and installing we need to select the JDK version we want to use. We can also access previous Java versions. There are minor and major versions where Java or JDK 12 is the latest. But the most popular, Java-compatible, performative JDK is Oracle JDK. There are different JDK providers like OpenJDK etc. Java Programming language provides standards for Java programming language and its libraries with JDK (Java Development Kit) and JRE (Java Runtime Environment). Oracle is the main contributor to the Java programming language. JDK also provides the JRE (Java Runtime Environment) which is used to run Java application or Java bytecode. JDK also provides a compiler for the Java programming language which can compile Java source code into Java byte code or Java binary. Java programming language uses this toolkit to load libraries, class, functions, etc. Java Development Kit or JDK is a tool kit used to develop Java applications.
