In this session, we will explore the key components that make Java a robust and widely-used programming language: JVM (Java Virtual Machine), JDK (Java Development Kit), and JRE (Java Runtime Environment). These components are essential for developing and running Java applications efficiently.
In this session, we'll explore the concept of RAM (Random Access Memory) and its functionality in computer systems. RAM is a crucial component in computing, enabling quick access and processing of data by the CPU.
In this lesson, we explore various numerical data types in Java, including byte
, short
, int
, and long
. We learn how to declare these data types, assign values to them, and understand their ranges and behaviors. Additionally, we discuss variable naming conventions and a concept called "looping" in data types.
Conditional statements in Java allow us to execute different blocks of code based on specific conditions. These are fundamental for controlling the flow of a program and making decisions.
In this session, we will delve into practical examples to understand how to use if-else statements effectively in Java. We will cover the concepts of statement precedence and condition precedence through a series of examples, including how to determine if a given year is a leap year.
Loops in programming are used to execute a block of code repeatedly until a specified condition is met. Java provides several types of loops:
In this session, we covered:
In this tutorial, we will delve into prime numbers, understand how to check if a number is prime, and extend this concept to identify all prime numbers within a given range. This guide will break down the concepts and code step-by-step, making it easy to follow and implement.
This study guide will cover the following key concepts and coding techniques for understanding and implementing Armstrong numbers and number crunching in Java. We'll break down the process, code, and logic in a detailed and easy-to-understand manner.
Patterns in Java involve printing symbols or characters in a specific order, creating visually recognizable structures. These exercises are commonly used in coding interviews to assess logical thinking and coding skills.
Welcome to the next session on advanced pattern programming. Building on the basics we've covered, we'll now dive into more complex patterns, including number-based and string-based patterns. These patterns are crucial for enhancing problem-solving skills and are often featured in technical interviews.
In pattern coding, the goal is to print shapes or designs using loops in programming. This guide will walk through creating pattern programs where rows and columns are not equal and will delve into how to handle various conditions and constraints.
Understanding Array Limits and Efficient Insertion Concept.
Array deletion involves removing an element from a specific index in an array and shifting subsequent elements to fill the gap. This operation is essential for managing dynamic arrays and efficiently using memory space.
In this tutorial session, we'll delve into the fundamental concepts of searching and sorting arrays in Java. These operations are essential for organizing and retrieving data efficiently in programming.
In this session, we will learn how to find the smallest and second smallest elements in an array efficiently. This problem is crucial for coding interviews and exams, where time complexity constraints are common. We will discuss:
The sliding window technique is a powerful method used to solve various array-related problems. It involves creating a "window" that slides over the array to evaluate a subset of elements at a time. This tutorial focuses on finding the maximum value within each subset (window) of a fixed size.
In this session, we delve into solving an array rotation problem frequently encountered in product-based company interviews. The goal is to rotate an array to the right by a given number of positions. We'll explore a detailed step-by-step approach to understand the problem, develop a solution, and optimize the code.
In this tutorial, we'll cover the problem of finding the minimum number of swaps required to rearrange an array such that all elements on the left of a given key element are less than the key and all elements on the right are greater than the key. This problem is useful for understanding array manipulation and optimizing operations within constraints.
In this session, we will learn about multi-dimensional arrays. A multi-dimensional array can be visualized as arrays within arrays, where a one-dimensional array is a simple list, a two-dimensional array can be seen as a grid or a matrix, and higher-dimensional arrays extend this concept further.
In coding interviews, one common type of problem involves multi-dimensional arrays, particularly the spiral matrix problem. Understanding how to navigate and manipulate these arrays is crucial. This guide will help you understand how to approach and solve spiral matrix problems, a skill that will serve you well in technical interviews.
StringBuilder
and StringBuffer
.In Java, strings are a fundamental data type used to represent text. They are objects of the String
class and are immutable, meaning once created, their values cannot be changed. However, Java provides several methods and classes to manipulate strings efficiently.
In the previous sessions, we covered strings and string buffers. Now, we will delve into string tokenizer, a feature that adds functionality not available in both strings and string buffers.
In this session, we will cover:
In this session, we'll cover how to handle word-based string questions in Java. Previously, we dealt with character-based manipulations where we alternated between uppercase and lowercase characters. This time, we’ll focus on reversing words in a string and alternately converting them to uppercase and lowercase.
This session covers the concept of number-based strings, where characters and numbers are intertwined in a single string. The goal is to extract and manipulate these components separately.
In this tutorial, we will explore how to create and use classes and objects in Java. We will define a class Dog
with properties and methods, and understand the concepts of static methods and variables. This session is a hands-on guide to understanding basic Object-Oriented Programming (OOP) concepts in Java.
In this session, we will explore two fundamental concepts in Java: Constructors and Encapsulation. These concepts are crucial for creating robust and maintainable code in Java.
In this session, we will explore the concept of polymorphism in Java, specifically focusing on method overloading. Polymorphism allows us to perform a single action in different ways, enhancing flexibility and reusability in code. We will understand method overloading by creating multiple methods with the same name but different parameters.
Inheritance is a fundamental concept in object-oriented programming (OOP) that allows one class to inherit fields and methods from another class. This promotes code reusability and establishes a hierarchical relationship between classes.
Introduction to Abstract Classes and Interfaces.
Exception handling in Java is a crucial aspect of robust software development. It enables the program to handle runtime errors gracefully and maintain normal application flow. This session will cover the basics of exception handling, the difference between errors and exceptions, and the mechanisms provided by Java to manage them.
In this class, we will discuss try
, catch and
finally
keywords to exceptions handle.
This session focuses on two keywords used in exception handling: throw
and throws
.
Multithreading in Java allows a program to run multiple tasks simultaneously, improving performance and resource utilization.
Multithreading in Java allows concurrent execution of two or more threads to maximize the utilization of the CPU. Each thread runs in parallel, enabling efficient performance and responsive programs.
