Arrays.deepToString()

For multi-dimensional arrays, the Arrays.deepToString() method provides a convenient way to print the contents.

Java

/*package whatever //do not write package name here */
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
        int[][] matrix 
            = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; 
        System.out.println(Arrays.deepToString(matrix)); 
        // Output: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] 
    } 
}
