Java: how to read and write array?

The following is the simple example to read and write array in java programming:

1. Basic array in Java


--------------------------------------------------------------------------------
import java.util.*;

public class array{
  public static void main(String[] args){

  int[] t_array = new int[10];
  
  //Write data to array
  for (int i = 0; i < t_array.length; i++)
  {
 t_array[i] = i;
  }

  int sum = 0;

  //Read data from array
  for (int i = 0; i < t_array.length; i++)
  {
 sum += t_array[i];
  }

  System.out.println(sum);
}
--------------------------------------------------------------------------------

2. Multi-dimensional arrays in Java

--------------------------------------------------------------------------------
import java.util.*;

public class array{
  public static void main(String[] args){

  int[][] m_array = new int[8][6];

  for (int i=0; i < m_array.length; i++) 
  {
     for (int j=0; j < m_array[i].length; j++) 
     {
         System.out.print(" " + m_array[i][j]);
     }
     System.out.println("");
  }
}
