[英]How do I get the right output for this array?
我正在尝试获取数组的特定输出。 将该数组放入while循环中以继续建立新数组,直到到达其计数器为止。 计数器和每个数组中的元素数量对齐,但是一旦我尝试获取输出,它就无法工作。 我应该解决什么才能解决?
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int i; int j; int n; int u;
int count = 0;
n = input.nextInt();
System.out.println("Times repeated: " + n);
while(count < n) //counter represents amount of times loop will occur
{
i = input.nextInt();
int[] numbers = new int[i];
System.out.println("Length of Array: " + i);//represents how many numbers within a line
count++;
for(j = 0; j < numbers.length; j++) //numbers within line
{
numbers[j] = input.nextInt();}
for(int p = 0; p < numbers.length - 1; p++) //prints specific values in line
{
numbers[p] = numbers[numbers.length - 1 ];
p = numbers[p];
System.out.println(p);
System.out.println(Arrays.toString(numbers)); }
input.close();}
} }
首次用户输入:
3
2
10
1
预期产量:10
相反,我得到1。我想要做的是从数组的其余部分减去数组的最后一个元素,以获得所需的输出。 这也包括最后一个元素。
代码工作正常,只需要同时close scanner outside while.
固定支架。
input.close();
外循环
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int i;
int j;
int n;
int u;
int count = 0;
n = input.nextInt();
System.out.println("Times repeated: " + n);
while (count < n) // counter represents amount of times loop will occur
{
i = input.nextInt();
int[] numbers = new int[i];
System.out.println("Length of Array: " + i);// represents how many numbers within a line
count++;
for (j = 0 ; j < numbers.length ; j++) // numbers within line
{
numbers[j] = input.nextInt();
}
for (int p = 0 ; p < numbers.length - 1 ; p++) // prints specific values in line
{
numbers[p] = numbers[numbers.length - 1];
p = numbers[p];
System.out.println(p);
System.out.println(Arrays.toString(numbers));
}
}
input.close();
}
