arrays Getting started with arrays Basic array in Java

Example

In Java, any object or primitive type can be an array. Array indicies are accessed via arrayName[index], e.g. myArray[0]. Values in an array are set via myArray[0] = value, e.g. if myArray is an array of type String[] myArray[0] = "test";

public class CreateBasicArray{
    public static void main(String[] args){

        // Creates a new array of Strings, with a length of 1
        String[] myStringArray = new String[1]; 
        // Sets the value at the first index of myStringArray to "Hello World!"
        myStringArray[0] = "Hello World!";
        // Prints out the value at the first index of myStringArray,
        // in this case "Hello World!"
        System.out.println(myStringArray[0]);
            
        // Creates a new array of ints, with a length of 1
        int[] myIntArray = new int[1];
        // Sets the value at the first index of myIntArray to 1
        myIntArray[0] = 1;       
        // Prints out the value at the first index of myIntArray,
        // in this case 1
        System.out.println(myIntArray[0]);     
        
        // Creates a new array of Objects with a length of 1
        Object[] myObjectArray = new Object[1];
        // Constructs a new Java Object, and sets the value at the first     
        // index of myObjectArray to the new Object.
        myObjectArray[0] = new Object();
    }       
}
