'javac' - Java Compilation Command and Options

Compiling Hello.java - My First Java Program

Option '-classpath' - Specifying Class Path

Option '-sourcepath' - Specifying Source Path

Two Types of 'import' Statements

'import' Statements Processed by 'javac'

Option "-g" - Controlling Debugging Information

Conclusions:

• "javac" is the standard compiler in JDK.
• "-sourcepath" specifies places where to search for source definitions of new types.
• "-classpath" specifies places where to search for class definitions of new types.
• Two types of "import" statements behave differently with "javac".
• Never distribute your class files with debugging information in them.
