The above block of code created an array of length 2 since we provided 2 values in the initialization. Initialize Array to Values UsingStreamin Java For Java 8 and above, we can make use ofStreamto initialize an array of Strings with given values. The below example illustrates this: ...
limiting the maximum size of the generated Java Virtual Machine code for any method, instance initialization method, or static initializer (the size of any code array) to 65534 bytes 如果方法的Java虚拟机代码恰好是65535字节长,并且以一条1字节长的指令结束,那么该指令就不能被异常处理程序保护。编译器...

long, then that instruction cannot beprotected by an exception handler. A compiler writer can work around this bugby limiting the maximum size of the generated Java Virtual Machine code for anymethod, instance initialization method, or static initializer (the size of anycode array) to 65534 ...
java8的时候去除PermGen,将其中的方法区移到non-heap中的Metaspace,因而SymbolTable也跟随Metaspace移到了non-heap中 SymbolTable symbolic references in Runtime Constant Pool 一个完整的类加载过程必须经历加载(Loading)、连接(Linking)、初始化(Initialization)这三个步骤 ...

The sercrets are not needed after such initialization. But in java string is not possible to clear it from memory (manualy nor by garbage collection)... So, it is basically forbiden to store secrets in Strings. Recommended way: Load secrets to char[], pass it to init proces, and clear...
