Question

我有这段代码：

    /* For loop to count 50 days */
    for (int n = 1; n <= 50; n++) {

        int solve = 0;
        solve = solve++;  
        item_1.removeDailyDemand();

        if ( n % 5 == 0){


        }
        if (solve == 5){

            item_1.isReOrderPoint();
        }

        System.out.print(n + "\t");
        System.out.println (item_1.getQuantityInStock() + "\t");

玩了很多年，对Java来说很新。我只是希望它增加＆＃34;解决＆＃34;因为它＆＃34; n＆＃34;同时运行for循环。

大部分时间都在尝试，没有结果！

谢谢

Answer 1

替换：

/* For loop to count 50 days */
for (int n = 1; n <= 50; n++) {
    int solve = 0;
    solve = solve++;

人：

/* For loop to count 50 days */
int solve = 0;       
for (int n = 1; n <= 50; n++) {
    solve++;

在每次迭代中，您将solve变量重置为0。并且solve = solve++没用，因为首先复制solve变量然后递增它。与solve++

相同

Answer 2

每次循环内部都声明求解为零：

/* For loop to count 50 days */
int solve = 0;
for (int n = 1; n <= 50; n++) {
    solve += 1;  
    item_1.removeDailyDemand();

    // same as your previous code
}

或者在类似的行上你可以使用：

/* For loop to count 50 days */
int solve = 0;
for (int n = 1; n <= 50; n++, solve++) {

让简单的Java工作
