(Java in Eclipse)
Write a method that returns the sum of all the elements in a specified column in a 2-D array using the following header:
public static int sumCol(int[][] m, int colIdx)
Included is a test class and a sample run
Extracted text: Test your program using the Test class Sample run First array: 14 11 13 12 18 15 13 13 19 16 15 17 Second array: 54 53 51 52 51 59 52 56 53 54 52 58 The sum of the first column in the first array is: 51
