How to find the two largest elements in an array with Java

Answer 1

public class MyClass {
    public static Integer[] getTheTwolargest(Integer[] arr) { 
        Integer max = Integer.MIN_VALUE, secondmax = Integer.MIN_VALUE;
   
        for (int i = 0; i < arr.length; i++) {
            if (arr[i] > max) {
                secondmax = max;
                max = arr[i]; 
            } else if (arr[i] < max && arr[i] > secondmax) {
                secondmax = arr[i]; 
            }
        }
        
        Integer[] arr_result = new Integer[2]; 
        arr_result[0] = max; 
        arr_result[1] = secondmax; 

        return arr_result;
    }
    public static void main(String args[]) {
        Integer[] arr = {7, 3, 0, 8, 2, 5, 99, 4, 6};

        Integer[] result = getTheTwolargest(arr); 
           
        System.out.println(result[0]);
        System.out.println(result[1]);
    }
}
 
 
     
       
       
/*
run:
       
99
8
       
*/
