Java Programming Fundamentals Syllabus

You can use arithmetic operations like a = a + b; b = a - b; a = a - b; to swap them.

You can reverse the number and check if it equals the original number.

You can iterate through the array and check if each number is divisible only by 1 and itself.

<p>You would implement <code>push(int value)</code> to add a value and <code>pop()</code> to remove and return the top value.</p> Signup and view all the answers

<p>Object-oriented programming focuses on objects and classes, promoting encapsulation and inheritance, while procedure-oriented programming is centered around sequential logic and functions.</p> Signup and view all the answers

<p>Encapsulation in Java is the bundling of data and methods that operate on that data within a single unit, usually a class, and restricting access to some of the object's components.</p> Signup and view all the answers

<p>Constructors are special methods invoked when an object is created, allowing for initialization of the object's attributes at the time of instantiation.</p> Signup and view all the answers

<p>Type casting in Java allows a programmer to convert one data type into another, which is essential for data compatibility and manipulation in operations.</p> Signup and view all the answers

<p>Java implements polymorphism primarily through method overloading and method overriding, allowing methods to behave differently based on the object invoking them.</p> Signup and view all the answers

<p>Java provides various control statements including <code>if</code>, <code>switch</code>, <code>for</code>, <code>while</code>, and <code>do-while</code> for managing the flow of program execution.</p> Signup and view all the answers

<p>The <code>switch</code> statement in Java enables multi-way branching by allowing a variable to be tested against a list of values, facilitating cleaner code in decision-making scenarios.</p> Signup and view all the answers

<p><code>continue</code> skips the current iteration and proceeds to the next one, while <code>break</code> exits the loop entirely.</p> Signup and view all the answers

<p>Literals in Java are fixed values that are directly represented in the code, such as numeric values, characters, or strings, and they serve as constant data points within the program.</p> Signup and view all the answers
