Use Case
Programming Language/Compiler is only a tool
Language translation
the compilation process
source code -> compiler -> assembly code -> assembler -> machine code
have syntax (form) and semantics (meaning)
Natural language
add 5 to the variable cnt
Java/C/C++ language
cnt = cnt + 5;
Assembly language
LDA CNT;ADDA#5;STA CNT
Machine language
B62000;8B05;B72000
Typical Java environment
Integrated Development Environments (IDEs)
MS Visual J++, Symantec's Visual Cafe, Borland's JBuilder, and IBM's Visual Age.
