(The JDK also contains a private JRE for use only by its tools see Private Versus Public JRE for more information.) As part of the JDK, this installation includes an option to include the public Java Runtime Environment. In this procedure, you will run the self-installing executable file to unpack and install the JDK. Similarly, if you were downloading the JDK installer for 64-bit systems for update 1.7.0_01, the file name jdk-7-windows-圆4.exe would become jdk-7u1-windows-圆4.exe.
