软件开发者面试百问-----怎样把字符串反转？你能不用临时的字符串么？

public class Test {
public static void main(String [] args) {
char [] chars = { 'A', 'B', 'C', 'D', 'E' };
reverse(chars);
for (int i = 0; i < chars.length; i++) {
System.out.print(chars[i]);
}
}

public static void reverse(char [] chars) {

int i = 0;
int j = chars.length - 1;
char temp = ' ';
while (i < j) {
temp = chars[i];
chars[i] = chars[j];
chars[j] = temp;
i++;
j--;
}
}
}
