嗨,我正在尝试反转字符串以制作回文。有人可以给我一个关于如何反转字符串的教程吗?我已经在线阅读了一些教程,并尝试将它们应用于我正在编写但没有成功的回文程序。
import java.util.Random;
public class IterativePalindromGenerator {
public static void main(String[] args) {
Random random = new Random();
int floorValue = 1;
int cielingValue = 20;
int randomNumber = random.nextInt(cielingValue - floorValue)
+ floorValue;
String alphabetLetters = "abcdefghijklmnopqrstuvwxyz";
for (int i = 0; i < randomNumber; i++) {
char generatedLetters = alphabetLetters.charAt(random
.nextInt(alphabetLetters.length()));
String generatedLetterSTRINGType = Character
.toString(generatedLetters);// converts char to string
System.out.print(generatedLetterSTRINGType);
}
}
}
