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.
Java bytecode is the instruction set of the Java virtual machine. Each bytecode is composed by one, or in some cases two, bytes that represent the instruction (opcode), along with zero or more bytes for passing parameters.f executing Java bytecode in a Java virtual machine is not desirable, a developer can also compile Java source code or Java bytecode directly to native machine code with tools such as the GNU Compiler for Java. Some processors can execute Java bytecode natively.
