people who learn Java do not know the Java virtual machine, it is really white learning. Why Java can cross-platform, because of the role of virtual machines, Java Virtual machine is the equivalent of a computer, it has its own memory structure,

The eval function of JS, which gives an expression a parameter, returns the value of an expression.Java's scripting engine can implement this functionality.Example:Stitch a string \uxxxx, Unicode hexadecimal code, and then print it out. That is,
