Organizing Package Names
- Package name is a combination of multiple words separated by dot (.) symbol.
- Each word in the package name represents one folder/directory in the file system.
Examples:
package com.javaworld.sms.struts;
package com.javaworld.sms.hibernate;
package com.javaworld.sms.ejb;
Package Structure Representation
🔥 Quick Understanding
.in package → folder separation- Package = directory structure + namespace
- FQCN →
package Name.class Name - Compilation with package → creates folders automatically
Lab452.java
package com.javaworld.p1;
class Lab452 {
public static void main(String str[]) {
System.out.println("Hello Guys!");
}
}
Lab453.java
package com.javaworld.p2;
class Lab453 {
public static void main(String str[]) {
System.out.println("Hello Guys!");
}
}
