Problem 1 Add the following code that creates and initializes a 20 array al Then, call the method print to print the contents of the array. Understand how we can traverse a 2D array using loops and indexes where the 1" index is visualized as a row of a table and the second index as a column of a table. Understand the passing of 2D arrays as arguments to methods. package lab18; public class Lab18 { static void print( int[][) a1) { System.out.print ln(); for ( int i =0; i < a1.length; ++i) { for ( int j =0; j < a1[i]. length; ++j) 3 4 7 8 10 11 System.out.print( al[i][j] + " "); System.out.println(); } 12 13 14 public static void main(String[] args) { int [) [] a1 = { 15 16 E 17 {1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12} }; 18 19 20 21 22 23 print( al ); 24 25 26 } 27 Output - lab18 (run) 8 run: 1 2 3 4 5 6 7 8 9 10 11 12 BUILD SUCCESSFUL (total time: 0 seconds) Problem 2 Overload method print with the following signature: static void print( String[][] al) The code inside print should be identical with the previous method print. String [) ) a2 - { {"john", "pau", "james" }, {"mary", "laura", "margaret"} };
