The array is a 2D array with 3 rows and varying number of columns. The row index is denoted by the first bracket and column index by the second bracket. 
myVals[1] corresponds to the second row {1, 8, 9}. 
Therefore, myVals[1].length returns the length of the second row, which is 3.

Int[][] MyVals = {{2, 4, 6}, {1, 8, 9}
