Demonstrates how to build a Java program that reads two names and ages, sorts the names alphabetically using for and while loops, and prints the ordered result.

Wraps up section 1 of the advanced Java programming course by introducing effective methods for scanning text files and processing large amounts of data, enabling bigger programs in section 2.

Learn how to use the substring method and the index of method for processing strings. Practice with string variables, character variables, and the charAt method, including strings from text files.

Explore the substring method in Java masterclass, learning how to return a specific section of text by choosing the start and end points, such as 5 and 7.

Practice using the substring method on a user-provided string to cut from a specified index. Learn how index of helps locate characters and avoid index out of bounds errors.

Explore how indexOf and lastIndexOf locate characters or strings in text, return zero-based positions, and how substring uses these positions to extract data.

Learn to use indexOf and lastIndexOf in Java to locate characters and substrings, then combine with substring to extract words from a sentence using zero-based indexing.

Learn to parse a full name input in Java using indexOf, lastIndexOf, and substring to split into first, middle, and last names and print them in a formatted layout.

Develop and refine a Java project in IntelliJ IDEA that parses a full name into first, middle, and last names using substring and space indexes, then prints the results.

Learn three key substring methods, master scanning and searching text data, and apply these techniques to future data processing tasks in Java.

Learn to create objects using the scanner to read text files and strings and use the print Rotto class to write text files, advancing your Java programming and OOP skills.

Learn the scanner concept in Java by exploring the Scanner class, its object, methods like next, next integer, next double, and next string, and how delimiters separate tokens.

Practice using the scanner to parse a string into string, int, double, and boolean values, then print each on its own line and close the scanner.

Change the scanner delimiter to parse non-whitespace data, read an unknown number of values with a loop and next methods, and count words from input.

Explore reading a text file with a file scanner that works with a land scanner, link them, loop to read lines, and close the scanners.

Prepare a Java project for file reading practice in IntelliJ IDEA. Create a resources directory and place a text file ready to be read by the file reader.

Practice reading a text file in Java using a Scanner, handle FileNotFoundException, parse lines with a hash delimiter, and print the initial, first name, last name, and age.

Explore the Java print writer, learn to write to a text file, close the writer, and continue where you left off by setting true to avoid overwriting.

Practice using the print writer to write to a text file with a file writer, handle io exceptions, and append user input until stop is entered.

Learn to implement a try and catch statement in Java to handle file not found errors, create clearer messages, and improve a program's reliability.

Develop a Java program in IntelliJ IDEA that reads two text files with a scanner, processes student data, and outputs results, with try-catch for file not found and io exceptions.

Develop a Java program in IntelliJ that reads and writes text files using a scanner and a hash tag delimiter, handling file not found and other exceptions with try-catch blocks.

Master Java basics to OOP by using the scanner to read strings and text files, process data, and store results in text files, progressing toward independent, larger projects.

Explore arrays as multi-value containers, from one-dimensional rows to two-dimensional tables and three-dimensional layers. Learn how the split method and substring separate tokens within strings and place them in arrays.

Explore arrays in Java, including one dimensional and two dimensional int arrays, how to declare with square brackets, assign values, and print specific positions using zero-based indexing.

Practice one-dimensional arrays in Java using for loops to input values via dialog and print them, while learning how the array length reveals capacity with zero-based indexing in IntelliJ IDEA.

Master two-dimensional arrays in Java by building nested for loops to input and output a 5x4 array. Learn to place values row by row and print them with spaces.

Explore the split method for string arrays to tokenize text and populate an array with tokens; split at whitespace or characters to determine token count.

Explore the split method by turning a sentence into tokens and storing them in an array, using whitespace to split the sentence.

The project teaches collecting two sport lists, storing as strings, splitting into arrays, using an if statement to compare lengths, and displaying the dominant student and their supports.

Develop a Java console program in IntelliJ that collects two players' sport lists via input dialog, splits them into arrays, compares lengths, and prints who plays more sports.

Apply arrays to hold many values, use scanners to read text files, and employ the split method to organize data, then prepare for object oriented programming with methods and classes.

Explore object oriented programming by creating objects through classes, defining reusable methods, and using a scanner to read text files, then process and output data.

Learn to define reusable classes and methods in Java, including void and value-returning methods, with practical examples like importing utilities and using scanner and split.

Create and use classes and void methods in Java by building a greeting class, writing a main method, and instantiating objects to print hello, illustrating core object oriented programming.

Create a typed method in Java to process a user's full name into initials and surname using an object-oriented approach. Call this top string method from main to return result.

Explore public and private variables within a class, showing how public variables are accessible across methods while private variables protect against user tampering.

Advance your Java skills by building a scanner class with a void method that reads files using object oriented programming. Prompt for file names and support multiple scans for efficiency.

Develop an object processing program in Java masterclass that uses a file reader class to read two text files, finds the oldest person, and writes initials and ages to output.

Master Java object-oriented programming in IntelliJ IDEA by building a final project that reads text files, processes data to find the oldest entry, and writes results to an output file.

Celebrates completing the Java masterclass, highlighting how learners progressed from little to advanced Java skills through projects and practice, gaining a head start for programming careers.
