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

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
[1] each instruction is represented by a single byte, hence the name bytecode, making it a compact form of data. The main examples are local variables in c subprograms and java methods Java syntax a snippet of java code with keywords highlighted in bold blue font the syntax of java is the set of rules defining how a java program is written and interpreted The syntax is mostly derived from c and c++
Unlike c++, java has no global functions or variables, but has data members which are also regarded as global variables. Dead store in computer programming, a dead store is a local variable that is assigned a value but is read by no following instruction
