src.zip in the jdk1.8.0_144 contains Float.java
That in turn refers to sun.misc.FloatingDecimal. I cannot find that anywhere in src.zip? Can anyone tell me where it is? I can find the source listed in grepcode: http://grepcode.com/file_/repository.grepcode.com/java/root/jdk/openjdk/6-b14/sun/misc/FloatingDecimal.java/?v=source
but obviously, the code must exist for my library to be calling it.
Even odder, in class Float:
public static float parseFloat(String s) throws NumberFormatException {
return FloatingDecimal.parseFloat(s);
}
However, searching the code that I can see (admittedly, only jdk1.6) does not even have method FloatingDecimal.parseFloat.
They do not include it in src.zip.
Per the JDK 8 README:
Java programming language source files for all classes that make up the Java core API (that is, sources files for the java., javax. and some org.* packages, but not for com.sun.* packages). This source code is provided for informational purposes only, to help developers learn and use the Java programming language. These files do not include platform-specific implementation code and cannot be used to rebuild the class libraries.
As you have found, you can get the source from 3rd party sources like Grepcode.
