Ideas in this flowchart

  • Java program execution begins through a main() method.
  • A Java class may contain many variables and methods.
  • A class is executable only if it contains a main() method.
  • After compilation and JVM startup, the JVM loads the class into memory.
  • The JVM starts executing the code contained in the main() method.
  • The main() method accepts an array of String types.
  • The String array communicates command-line arguments to the program.
  • The args array stores the arguments as strings.

"Every executable program has to have a beginning: a point at which the program starts to execute. In Java, a class may contain many variables and methods, but a class is only executable if it contains a main() method. When a Java class is compiled and the JVM is started, the JVM loads the class into memory and starts executing code contained in the main() method. In addition, our main() method takes an array of String types which serve to communicate any command line arguments provided to the program (review Section 2.4.4 for details). The array, args stores the arguments as strings."
