如何以相同的方式随机化两个ArrayList？
我有两个arraylist filelist并且imgList彼此相关，例如，与“ e1.jpg”相关的“ H1.txt”。如何imgList根据的随机化自动对列表进行随机化fileList？像在excel中一样，如果我们对某些列进行排序，其他列会自动跟随吗？ String [] file = {"H1.txt","H2.txt","H3.txt","M4.txt","M5.txt","M6.txt"}; ArrayList<String> fileList = new ArrayList<String>(Arrays.asList(file)); String [] img = {"e1.jpg","e2.jpg","e3.jpg","e4.jpg","e5.jpg","e6.jpg"}; ArrayList<String> imgList = new ArrayList<String>(Arrays.asList(img)); //randomized files Collections.shuffle(fileList); 随机化后的输出，例如： fileList = {"M4.txt","M6.txt","H3.txt","M5.txt","H2.txt","H1.txt"}; 预期的输出： imgList = {"e4.jpg","e6.jpg","e3.jpg","e5.jpg","e2.jpg","e1.jpg"};
