Introduction to Java Arrays

 

In Java, an array lets you store multiple values in a single variable. Super useful when you’re working with a list of items!

//Structure of arrays in java

int[] numbers = {10, 20, 30, 40};

//Accessing Elements

System.out.println(numbers[0]); // 10

System.out.println(numbers[2]); // 30

💥 Array Properties

• Fixed size (you can’t change its length)

• Index starts at 0

• numbers.length gives you the number of elements
