I'm trying to run this code that returns the maximum value in the given array. I'm brand new to Java so I would greatly appreciate any debugging tips.
public class maxVal { public static int max(int[] m) { int maxSoFar=m[0],i; for (i=1; i<m.length;i++) { if (m[i]>maxSoFar) maxSoFar=m[i]; } return maxSoFar; } public static void main(String[] args) { int[] numbers = new int[]{9, 2, 15, 2, 22, 10, 6}; max(numbers); } }
I think you need to see the answer in the console?
When you run max method it will return the maximum value in the given array. so to see it in the console you have to print it using System.out.println(). or you can also assign it to another variable to use it in somewhere else.
Your code is actually working but you ignore the return value by max method.
here is your code with System.out.println() to print the maximum value
public class maxVal { public static int max(int[] m) { int maxSoFar=m[0],I; for (i=1; i<m.length;i++) { if (m[i]>maxSoFar) maxSoFar=m[I]; } return maxSoFar; } public static void main(String[] args) { int[] numbers = new int[]{9, 2, 15, 2, 22, 10, 6}; int maxVal = max(numbers); System.out.println(maxVal); } } 
maxmethod returns a value so you may want to print it out.
