Create your first Java program by defining a class and a main method that prints hello. Save the file, compile with javac, and run with java to display the message.
In Java, a class contains attributes and methods. Use get and set methods to access attributes, and a main method demonstrates compiling and running to show the attribute value.
Create a public double method to calculate a circle's area, initialize and compute area as r squared times 3.14, call it from main, and print the result to verify.
Create a Java method to calculate taxes based on salary using defined business criteria, via a separate class, and return the tax amount to the main program.
Learn to read user input in Java using the scanner class, create a scanner instance, read a number as double, multiply by four, and display the result.
Explore how Java implements inheritance by extending a superclass, sharing attributes and methods with a child class, and using calc salary and calc deductions to compute gross salary.
Learn to use private attributes with set and get methods to control access, set hours and rate, and compute salary by multiplying hours by rate.
Explore entity relationship diagrams for modeling customers, accounts, and transactions in a relational database, detailing primary and foreign keys, one-to-many relationships, and table structures.
Import required modules for database programming in Java. Create a Connection object with DriverManager, then use Statement and ResultSet to execute queries, display data, and handle SQL exceptions.
