Execution Process, Entry Point, Input and Output
This chapter provides tutorial notes and tutorial examples on Java program execution process. Topics include Java program creation, compilation and execution; the main() method - execution entry point; execution console, input and output data streams.
Creating, Compiling and Executing Java Programs
main() Method - Java Execution Entry Point
Java Execution Console - "in", "out" and "err" Data Streams
- 3 steps are involved in building a Java application: creating source
code, compiling source code and executing the compiled code.
- "public static void main(String a)" is the execution entry point
when a class is launched in the Java Virtual Machine (JVM).
- JVM provided 3 default I/O data streams to all applications: "in", "out" and "err".
