java 增加换行符_Java每n行追加换行符

String[] names = new String[18];

names[0] = “James Raider”;

names[1] = “Calm Hain”;

names[2] = “Ewds Ashby”;

names[3] = “Gedge Taylor”;

names[4] = “Hay Fin”;

names[5] = “Ian Hilton”;

names[6] = “John Coke”;

names[7] = “Nathan Dryer”;

names[8] = “Jess Maguire”;

names[9] = “Jamie Loyal”;

names[10] = “Luke Shwinger”;

names[11] = “Parrot Tom”;

names[12] = “John Clarke”;

names[13] = “Steven Mason”;

names[14] = “Shing Lao”;

names[15] = “Tom Brook”;

names[16] = “Arthitus Pint”;

names[17] = “Yifan Yao”;

StringBuilder sb = new StringBuilder();

ArrayList list = new ArrayList();

for (int i = 0; i < names.length; i++) {

list.add(i);

}

Collections.shuffle(list);

for (int i = 0; i < names.length; i++) {

field.append(names[list.get(i)] + “\n”);

for (int u = 0; u < (Integer) number.getValue(); u++) {

field.append(“\n”);

}

}

我试图每次都在输出中添加新行number.getValue()。我正在做的是在每行之后添加它，但是我只希望它在设置一定次数后创建它。

例子：3次
