java 数组如何按指定元素拆分
给定一个数组,如何将其按照特定元素(例如 85)拆分为多个新数组?
public void mymethod(int[] arr, int splitvalue) {
list> result = new arraylist<>();
list temp = new arraylist<>();
for (int num : arr) {
if (num == splitvalue) {
if (!temp.isempty()) {
result.add(new arraylist<>(temp));
temp.clear();
}
temp.add(num);
} else {
temp.add(num);
}
}
result.add(temp);
for (list subarray : result) {
system.out.println(arrays.tostring(subarray.toarray()));
}
}
使用该方法:
int[] arr = {85, -86, 13, 2, 99, 99, 99, 99, 98, 98, 99, 99, 99, 99, 20, 85, -86, 13, 2, 99, 99, 99, 99, 99, 99, 99, 85, 12, 85, -86, 13, 2, 99};
mymethod(arr, 85);输出:
