我试图使用java从用户输入的数组中删除重复项,并且我得到一个重复变量的错误,这是我到目前为止:
public class sortedArray {
static int alter(int array[], int n) {
if (n == 0 || n == 1)
return n;
int[] arr = new int[n];
int r = 0;
for (int i = 0; i < n - 1; i++)
if (array[i] != array[i + 1])
arr[r++] = array[i];
arr[r++] = array[n - 1];
for (int i = 0; i < r; i++)
array[i] = arr[i];
return r;
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int[] array = new int[49];
int n = array.length;
System.out.print("enter some integers (enter -9999 to stop): ");
for (int i = 0; i < array.length; i++) {
array[i] = input.nextInt();
if (array[i] == -9999) {
break;
}
n = alter(array, n);
for (int i = 0; i < n; i++) //getting error here on the i
System.out.print(array[i] + " ");
}
}
}
任何帮助都将不胜感激。

您的问题是您尝试在第一个i
循环内重新声明for
。您需要在第二个循环中使用另一个计数器变量:
for (int i = 0; i < array.length; i++) {
array[i] = input.nextInt();
if (array[i] == -9999) {
break;
}
n = alter(array, n);
for (int j = 0; j < n; j++) //getting error here on the i
System.out.print(array[j] + " ");
}
