Java中的即时编译 So,Java是即时编译为机器代码的。想要检查编译机器代码,我们可以启用多个JVM参数: -XX:+ PrintCompilation:通过这个参数,我们可以得到方法编译结果的输出。其输出的样例: 711java.lang.String::indexOf(70bytes) 732sun.nio.cs.UTF_8 $Encoder::encode(361bytes) ...
zic -L no longer omits the POSIX TZ string in its output. zic fixes for truncation and leap second table expiration. zic now follows POSIX for TZ strings using all-year DST. Fix some localtime crashes and bugs in obscure cases. zdump -v now outputs more-useful boundary cases. tzfile.5...
In Java programs, it is common to allocate temporary objects in the course of a computation. For example, concatenating two strings generates aStringBufferobject that is thrown away as soon as the result string is available. The standard programming style for Java programs encourages producing a ...
