A Bit More About Arrays

In this lesson, an explanation of Character Arrays, String Arrays, Arrays & Methods is provided.

We'll cover the following...

Let’s discuss how to declare and use arrays of char & String data types.

Character Arrays

We can declare an Array of char in which we can store characters. Let’s write a code to declare and initialize a character array.

Java
class CharArr {
    public static void main(String args[]) {
        char[] chArray1 = {
            'a',
            'b',
            'c'
        }; //initialization of first char array
        char[] chArray2 = new char[5]; //instantiation of second char array
        int index = 0;
        for (char i = 'v'; i <= 'z'; i++) { //Assiging char values to second array using loop
            chArray2[index] = i;
            index++;
        }
        //printing out the stored values in the arrays
        System.out.print("The Values stored in ChArray1 are: ");
        for (int i = 0; i < chArray1.length; i++) {
            System.out.print(chArray1[i] + " ");
        }
        System.out.println();
        System.out.print("The Values stored in ChArray2 are: ");
        for (int i = 0; i < chArray2.length; i++) {
            System.out.print(chArray2[i] + " ");
        }
    }
}

Note: Our AI Mentor can explain the above code as well.

The above example has a loop that uses char variable. Each char value is represented by a number, so i++ ...
