java - 在 Java 中操作数组。陷入困难的家庭作业

Question

我是 Java 新手，本学期正在学习编程类(class)。我们有作业要交，我很挣扎。我很高兴这对于经验丰富的程序员来说很容易，但对我来说这是一个令人头疼的问题。这是第一个问题。

public int countInRange(int[] data, int lo, int hi)

For this, you have to count the number of elements of the array, data, that lie in the range >>lo to hi inclusive, and return the count. For example, if data is the array {1, 3, 2, 5, 8} >>then the call

countInRange(data, 2, 5)

should return 3 because there are three elements, 3, 2 and 5 that lie in the range 2 .. 5.

这是我到目前为止所做的:

/**
 * Count the number of occurrences of values in an array, R, that is
 * greater than or equal to lo and less than or equal to hi.
 *
 * @param  data  the array of integers
 * @param  lo   the lowest value of the range
 * @param  hi   the highest value of the range
 * @return      the count of numbers that lie in the range lo .. hi
 */
public int countInRange(int[] array, int lo, int hi) {
    int counter = 0; 
    int occurrences = 0;
    while(counter < array.length) {
        if(array[counter] >= lo) {
            occurrences++; 
        }
        counter++;
    }
    return occurrences;
}

Answer 1

if(array[counter] >= lo && conditionforhighcheck)
{
//Then only update occurence count
}

因为作业的原因，我没有输入代码。我给了指点。
