Arrays
Fundamentals
In this Kata your job is to find the biggest Integer in an Array and return it as such.
'1,2,3,4' -> '4'
The Integers passed can be non-negativ but will always be valid numbers.
import java.util.*; public class Kata { public static int findMax(int[] my_array) { int max = my_array[0]; for(int i : my_array) { if(i > max) max = i; } return max; } }- import java.util.*;
- public class Kata {
- public static int findMax(int[] my_array) {
// Write a method that returns the largest integer in the list.// You can assume that the list has at least one element.Arrays.sort(my_array);return (my_array[my_array.length-1]);- int max = my_array[0];
- for(int i : my_array) {
- if(i > max) max = i;
- }
- return max;
- }
