问题 We currently have code compiled in Java 8 but we are running that on Java 11 VM. Now we are trying to move our code to Java 11 compile time as well. Wondering if there are any benefits to compiled code in Java 8 vs Compiled code in Java 11 performance-wise, since both compilers will produce different class files (bytecode)? How does one differ from the other in terms of efficiency? 回答1: javac is not an optimizing compiler, so in general, don't expect it to produce "faster" bytecode from
