基本上概括在标题中。https://ideone.com/E2BMS8 <--这是代码的链接。我理解如果你不想点击它，所以我也会把它粘贴在这里。只会杂乱无章。该代码应该翻转字母但将单词保持在相同的位置。不过，我想自己弄清楚那部分。只需要有关运行时错误的帮助。
import java.util.*;
class Ideone {
public static void main (String[] args) throws java.lang.Exception {
Scanner input = new Scanner(System.in);
String sent, accum = "";
char check, get;
int len, count = 0;
System.out.print("Please enter the sentance you want reversed: ");
sent = input.nextLine();
len = sent.length();
for (int i = 0; i < len; i++) {
check = sent.charAt(len - i);
count += 1;
if (check == ' ') {
for (int p = 0; p < count; p++) {
while (p < count) {
get = sent.charAt(len - p);
accum += (get + ' ');
}
}
}
}
System.out.println("Reversed: " + accum);
}
}
错误String index out of range是由于 len 比索引范围大 1 造成的。删除索引上的一个，如下所示：
import java.util.*;
public class Ideone {
public static void main (String[] args) throws java.lang.Exception {
Scanner input = new Scanner(System.in);
String sent, accum = "";
char check, get;
int len, count = 0;
System.out.print("Please enter the sentance you want reversed: ");
sent = input.nextLine();
len = sent.length();
for (int i = 0; i < len; i++) {
check = sent.charAt(len - i - 1);
count += 1;
if (check == ' ') {
for (int p = 0; p < count; p++) {
get = sent.charAt(len - p - 1);
accum += (get + ' ');
}
}
}
System.out.println("Reversed: " + accum);
}
}
