我希望我的代码每行打印10个数字并计算有多少个数字。我也希望能够找到最大数量。我在弄清楚如何找到最大值时遇到了麻烦。这是我的代码。

int valCount = 0;
int numCount =0;

while (startingNum > 1) {
 int count = 0;
 System.out.print(startingNum + " ");
  valCount++;

  if(valCount%10 ==0)
    System.out.println();
  if (startingNum % 2==0) {
    startingNum = startingNum/2;
    numCount++;
} else {
    startingNum = (startingNum*3) +1; 
    numCount++;
 }
}

您可以使用一个计数器,在每次打印时增加它,当您达到10的倍数时,换一行,也为了对齐不同的元素,我建议使用printf,这里我设置为{ {1}},因为最大位数为4位数字,如果最高位数达到6位数字,请使用%5d

%7d

Demo code将给您:

int valCount = 0;
while (startingNum > 1) {
    System.out.printf("%5d", startingNum);
    valCount++;
    if(valCount%10 ==0)
        System.out.println();
    if (startingNum % 2==0) {
        startingNum = startingNum/2;
    } else {
        startingNum = (startingNum*3) +1; 
    }
}
System.out.printf("    1");

这是正确的代码:

public static void main(String[] args) {
    int startingNum = 27;
    int counter = 0;
    while (startingNum > 1) {
        counter++;
        System.out.print(startingNum + " ");
        if (counter % 10 == 0)
            System.out.println();
        if (startingNum % 2 == 0) {
            startingNum = startingNum / 2;
        } else {
            startingNum = (startingNum * 3) + 1;
        }
    }
    System.out.println(1);
}
