    Default How do you return a array from a method, back into the main method that prints out stuff?

    Id like to know how to return a new array i wrote in a method below the main method. I want to print the array but system.out.print doesn't work for arrays apprently. Do you know what structure i should use?

    i think you use like somethingsomething. output ( [] arrray name)

    im not sure.

    Default Re: How do you return a array from a method, back into the main method that prints out stuff?

    Id like to know how to return a new array i wrote in a method below the main method.
    just make a return type of array.
    Example:
    public int[] myIntArray() {
         int[] myArr = new int[3]; // creating an array with length of 3
         // assigning desired value for each element
         myArr[0] = 1;
         myArr[1] = 2;
         myArr[2] = 3;
         return myArr;
    }
    example codes above will return an array of int.
    note: you can also create a method above your main method. the order/place of methods in your class doesn't matter.

    I want to print the array but system.out.print doesn't work for arrays apprently.
    you can iterate the array from first element to last element (or vice versa) and print it.
    Example:
    public static void main(String[] args) {
          int[] myArr = {1, 2, 3}; //creating an array
          // printing it using enhance loop
          System.out.println("Printing array using enhance loop");
          for (int i : myArr) {
                System.out.println(i);
          }
     
          // printing array using index of element
          System.out.println("Printing array using index");
          for (int i = 0; i < myArr.length; i++) {
                System.out.println(myArr[i]);
          }
    }

    And lastly, I suggest you to read this Arrays (The Java™ Tutorials > Learning the Java Language > Language Basics)
