在Java整数数组中获取下一个索引

Question

// random_integers is an array of random integers of size 10
Arrays.asList(random_integers);

for (int n : random_integers) {
    if (n == number) {
        System.out.println("Search Value: "
                + number
                + " found at location: "
                + Arrays.asList(random_integers).indexOf(n)
                + " in the unsorted array");
        }
    }

谢谢你。

Answer 1

这是indexof的行为。相反，使用传统的for循环，只使用当前循环变量

for (int i = 0; i < random_integers.length; i++){
    if (random_integers[i] == number){
        System.out.println("Search Value: " + number + " found at location: " + i);
    }
}
