How to Use InstanceOf Operator in Java

1. How to Use InstanceOf Operator in Java

Sometimes we need to know what data type an object is: This lesson will explain the instanceof keyword in Java and provide code examples of its use and function.

When to Use Static Methods in Java

2. When to Use Static Methods in Java

In this lesson, we'll take a look at Java, what it is, what static methods are, and when to use static methods. At the end, you should have a good understanding of this current technology.

Reflection API in Java: Purpose & Examples

3. Reflection API in Java: Purpose & Examples

Like a mirror on our code, Java reflection lets us see what is happening when our Java programs run. This lesson will explain the purpose of reflection in Java and provide examples.

String Declaration in Java

4. String Declaration in Java

A string in Java is useful for holding text and numeric data. This lesson will cover the different methods used to declare a string variable in Java, providing working code examples.

Java Integer: Max Value & Min Value

5. Java Integer: Max Value & Min Value

Integer values in Java can only hold a certain range of values. This lesson will discuss the minimum and maximum values for an integer and provide code examples for finding these values.

Java ArrayList Add Method: Code & Examples

6. Java ArrayList Add Method: Code & Examples

The power of ArrayList (versus a standard array) is that we can add members to the list. This lesson will define the ArrayList add function and provide working code examples.

ArrayList Get Method in Java: Code & Examples

7. ArrayList Get Method in Java: Code & Examples

The Java ArrayList has many more functions than standard arrays. In this lesson, we will define the ArrayList get method, and provide working code examples to highlight its use in programming.

How to Check If a String is an Integer in Java

8. How to Check If a String is an Integer in Java

Strings in Java are powerful because they can hold text, numbers, or any other characters. Sometimes, we need to know if the string is a number. This lesson will show you how to do this correctly.

How to Iterate Set in Java

9. How to Iterate Set in Java

A Set in Java is a collection of data elements where every item is unique. This lesson will show you how to walk through a Set in Java, providing working code examples along the way.

Java Random: Method & Examples

10. Java Random: Method & Examples

This lesson will teach you how to generate random numbers in Java. We will look at an example of calculating the revenue generated by an airline on a hypothetical flight from Chicago to New York.

Java Absolute Value: Method & Examples

11. Java Absolute Value: Method & Examples

Java provides a wealth of math functions. This lesson will cover the Java method for determining the absolute value of a number. Working code examples are provided, covering the data types for which absolute value can be found.

How to Use Pi Constant in Java

12. How to Use Pi Constant in Java

Computer programs can help us with numerous math functions. Java provides a huge library of tools and functions for mathematical operations. This lesson covers the use of pi in Java.

Colors in Java: Class Constants & Codes

13. Colors in Java: Class Constants & Codes

The Internet would be boring without colors. Java applets and programs are able to render all colors of and under the rainbow. This lesson will cover the color constant and color codes in Java applications.

Reflection in Java: Examples & Mechanism

14. Reflection in Java: Examples & Mechanism

One of the powerful features of Java is the ability to write code that acts as a mirror, showing us run-time features of the code. This lesson will explain reflection and provide code examples.
