Question

Write a Java program that reads a 1D array of integers from standard input and returns it.

Answer 1

//TestCode.java
import java.util.Scanner;
public  class TestCode {
    public static int[] readArray(){
        int size;
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter size of array: ");
        size = scan.nextInt();

        int arr[] = new int[size];
        System.out.println("Enter "+size+" values for array");
        for(int i = 0;i<size;i++){
            arr[i] = scan.nextInt();
        }
        return arr;
    }

    public static void main(String[] args) {
        int arr[] = readArray();
        System.out.println("\nArray is:");
        for(int i = 0;i<arr.length;i++){
            System.out.print(arr[i]+" ");
        }
        System.out.println();
    }
}

Output:

Enter size of array: 5 Enter 5 values for array 6 3 5 4 2 Array is: 6 3 5 4 2 Process finished with exit code 0
