Output 2 arrays in 1 new array

Question

public class Program
{
static int[] h1 = {2,3};
static int[] h2 = {4,5};
public static void main(String[] args) {
int[][] h3 = {h1, h2};
System.out.println(h3);

}
}

This is the only code that makes sense for me and doesn’t end up with errors when i’m trying to output the two strings h1 and h2 together as h3 = {2,3,4,5}
But it somehow doesn’t work either and outputs nothing, can someone help me make this work?

Answer 1

You are making 2D array and holding array reference inside.
To get combined array values in 1D :
Create array of size h1.length + h2.length then copy values into h3 array..

int[] h3 = new int [h1.length+ h2.length];
First copy h1 values next h2.
