Java Array find the smallest index of the largest element

Introduction

Use a variable named max to store the largest element

Use a variable named indexOfMax to denote the index of the largest element.

Initially max is array[0], and indexOfMax is 0.

Compare each element in array with max, and update max and indexOfMax if the element is greater than max. 



public class Main {
  public static void main(String[] args) {
    int[] array = new int[5];

    for (int i = 0; i < array.length; i++) { 
      array[i] = (int)(Math.random() * 100); 
    } /*from  w w w  .j av a2 s  . com*/
    
    for (int i = 0; i < array.length; i++) { 
      System.out.print(array[i] + " "); 
    } 

    double max = array[0]; 
    int indexOfMax = 0; 
    for (int i = 1; i < array.length; i++) { 
       if (array[i] > max) { 
        max = array[i]; 
        indexOfMax = i; 
      } 
    } 

    System.out.println(max+" @ "+ indexOfMax);
  }
}
