@H_502_1@我在Eclipse中使用Jfugue,并且代码中有音乐字符串列表.当我运行代码时,它会播放所有代码,但是我想一次随机播放一次.
@H_502_1@到目前为止,我正在使用：
@H_502_1@
Pattern pattern = new Pattern ("A");
Player.play(A);
Pattern pattern = new Pattern ("B");
Player.play(B);
for(int i = 0; i < numberOfTest; i++) {
int index = (int)(Math.random() * 10);
System.out.println(strings[index]);
最佳答案
将它们放入列表,然后将其洗牌：
@H_502_1@
List<Pattern> allPatterns = Arrays.asList(new Pattern ("A"),new Pattern ("B"),... more patterns);
Collections.shuffle(allPatterns);
// by using the for-each loop
for (Pattern onePattern : allPatterns) {
player.play(onePattern);
}
// alternatively,turn the list back into an array and play that
player.play(allPatterns.toArray(new Pattern[0]);
