Through his first six years in office, Franklin Roosevelt spent much of his time trying to bring the United States out of the Great Depression. The President, however, certainly did not ignore America's foreign policy as he crafted the New Deal.
Bytecode may often be either directly executed on a virtual machine (i.e. interpreter), or it may be further compiled into machine code for better performance.ome systems, called dynamic translators, or  just-in-time  (JIT) compilers, translate bytecode into machine language as necessary at runtime: this makes the virtual machine hardware-specific, but doesn't lose the portability of the bytecode itself.
from the linked page above: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters.
