,Chapter 1 — Introduction to Programming and
Java
Learning Objectives
1. Define programming and its role in problem-solving.
2. Describe the Java compilation and execution process.
3. Write, compile, and run a basic Java program.
4. Understand the structure of a Java class and the main method.
Key Definitions
Term Definition
Program A sequence of instructions that a computer executes.
Source Code Human-readable code written in a programming language.
Compiler A program that translates source code into machine code.
Bytecode Intermediate code produced by the Java compiler; executed by the JVM.
JVM Java Virtual Machine — executes Java bytecode.
Class A blueprint for objects; every Java program is built from classes.
main Method The entry point of a Java application.
1.1 The Java Execution Model
Java source code ( .java ) is compiled by javac into bytecode ( .class ). The JVM executes the
bytecode on any platform, giving Java its "write once, run anywhere" property.
1.2 A First Java Program
public class Hello {
public static void main(String[] args) {
System.out.println("Hello, world!");
}
}
The class name must match the filename. System.out.println prints a line to the console.

CPSC 1001 teaches students majoring in any subject area how to program a computer and solve
problems. No prior programming experience is required.
Practice Questions
1. What is the difference between source code and bytecode?
2. Write a Java program that prints your name.
3. Why must the class name match the filename?
Answer Key
1. Source code is human-readable; bytecode is the compiled intermediate executed by the JVM.
2. public class Name { public static void main(String[] args) {
System.out.println("Your Name"); } }
3. Because the Java compiler expects the public class name to match the .java file name.
Chapter Summary
Concept Summary
Java Model Source → bytecode → JVM execution.
Class Building block of Java programs.
main Entry point of a Java application.
Quick Revision Checklist
