Access a certain array inside a method-CodePudding

I want to have multiple ASCII art figures which I want to store inside different arrays.

I learned about methods in Java that they are used for splitting code into smaller parts. Therefore, my idea is to put the art into individual arrays inside a method, so it's tidy.

Is there a way to do so? I made an example code to show how I imagine this.

My Google search about how to access a certain array inside a method didn't give me anything I can use. I apologize if there already is a thread about this topic.

public class Main {
    public static void main(String[] args) {
        System.out.println(divArr(arr2[1])); // expected output 20
    }

    public static void divArr() {
        int arr1[] {1, 2, 3};
        int arr2[] {10, 20, 30};
    }
}

CodePudding user response：

This is not the idea of functions. functions are actions, they accept parameters, calculate stuff and return a value. for example this is a function that returns the average of 3 numbers:

public static int avarage(int a, int b, int c) {
    int sum = a   b   c;
    int result = sum / 3;
    return result;
}

You probably found information about javascript's dictionary, which have different syntax from java's function, although both of them have { and }

You can use the following approach:

public static class Main {
    public static int[] arr1 = {1,2,3};
    public static int[] arr2 = {10,20,30};

    public static void main(String[] args) {
        System.out.println(arr2[1]);
    }
}

in this code, arr1 and arr2 are static variables.

You can also use a Map or a Class instead

EDIT:

another approach will be to use 2 dimensional array:

public static class Main {
    public static int[][] frame1 = {
                                     {1,2,3},
                                     {10,20,30}
                                   };
    public static int[][] frame2 = {
                                     {4,5,6},
                                     {40,50,60}
                                   };

    public static void main(String[] args) {
        System.out.println(frame1[1][1]);
    }
}
