Find largest Number in an Array

Solution

• Set the first element as largest.
• Loop through the array and check if current value > largest, then set current value to largest.

package com.java.programs;

public class LargestNumber {

    public static int findLargestNumber(int numbers[]) {
        int largest = numbers[0];
        for (int number: numbers) {
            if (number > largest) {
                largest = number;
            }
        }
        return largest;
    }

    public static void main(String[] args) {
        int[] numbers = {2,5,12,3,7,9,1};
        System.out.println(findLargestNumber(numbers));
    }

}
