Become a Junior Java Software Developer

Declare and define variables such as string, integer, and double; compute annual salary from rate, hours per week, and weeks per year; print the salary with career context.

Learn arrays as ordered data containers, declare and define arrays (such as cities or states), access elements by zero-based indices, set sizes, and print values while avoiding out-of-bounds errors.

Solve lab one implementing a sum from 1 to n with a for loop, a recursive factorial, and min, max, and average calculations for an array in Java.

Explore the basics of object-oriented programming by modeling a person as a class with name, email, and phone, and using methods like walk and sleep to operate on instances.

Understand how static relates to the class, not the object, with a routing number. Learn how final acts as a constant and how static final combines for methods and properties.

Explore how a class extends a parent object class and inherits its variables and methods, override the to string method, and CD account extends it with interest rate and compound.

Apply encapsulation by privatizing variables and exposing them through public API methods with getters and setters to control access and protect internal state.

Explore interfaces as a contract that outlines methods like set rate and increase rate, implemented by bank accounts and loans to enable reusable architecture.

Create a Java student class with encapsulation and a constructor. Form a user id and email from name and SSN, and enable enroll, pay, balance, and show courses.

Discover how to handle Java exceptions with try-catch blocks, catching divide-by-zero and array index out of bounds errors, and use finally to run code regardless of outcomes.

Learn to read data from a file in Java by defining the file path, creating a File and BufferedReader, reading lines, and handling file not found and input output exceptions.

In this lab, read a passwords.txt file, iterate over each password, and verify it meets criteria—contains a number, a letter, and a special character—using Java.

Explore data structures in java, comparing static arrays with dynamic collections, and learn common java collections: lists, sets, maps, and how to traverse them with generics.

Traverse a double array as a 3 by 4 matrix of users, extracting first name, last name, email, and phone while using length to derive rows and fields.

Learn to read and parse a CSV file in Java by buffering and splitting lines on commas, storing rows in a dynamic list of string arrays, and printing the results.
