一行是 for 循环的第一行 for (int x = 0; x < capacity ; ++x) 我也三重检查了条件是否正确,应该是。容量为 5,这意味着对象位置数组将位于 0、1、2、3、4,因此根据我对数组的了解,从 0 开始 x 应该是正确的。 库类(带循环的) package exercises; public class Library { private

start --> getInput getInput --> loop loop -- 循环每个元素 --> process process --> loop loop -- 完成遍历 --> end 通过这个流程图,我们可以清晰地看到循环JSONArray的整个过程:获取JSONArray -> 循环遍历JSONArray -> 处理每个元素 -> 结束。 结论 通过本文的介绍,我们了解了如何在JAVA8中循环处理...

for(int i=0;i<n;i++) { a[i]=sc.nextInt(); } As this loop iterates n number of times, the scanner method calls the .nextInt() method each time to take an int value input from the user and store it at the i position in the array. In the last line of the main method,...
