A local variable reference in the function or block in which it is declared overrides the same variable name in the larger scope Dead stores waste processor time and memory, and may be detected through the use of static program analysis, and removed by an optimizing compiler. In programming languages with only two levels of visibility, local variables are contrasted with global variables

List of java bytecode instructions this is a list of the instructions that make up the java bytecode, an abstract machine language that is ultimately executed by the java virtual machine
[1] the java bytecode is generated from languages running on the java platform, most notably the java programming language.
The main examples are local variables in c subprograms and java methods In the case of static local variables, the variable is created when the program initializes, and destroyed only when the program terminates, as with a static global variable, but is only in context within a function, like an automatic local variable. Register allocation in compiler optimization, register allocation is the process of assigning local automatic variables and expression results to a limited number of processor registers. [1] each instruction is represented by a single byte, hence the name bytecode, making it a compact form of data.
Dead store in computer programming, a dead store is a local variable that is assigned a value but is read by no following instruction
