字符串倒序输出的两种方法

方法一：利用String类的toCharArray(),再倒序输出数组.

Java代码

1 public class javatest {

2 public static void main(String[] args) {

3 String originalString = "abcdefg";

4 String resultString = "";

5 char[] charArray = originalString.toCharArray();

6 for (int i = charArray.length-1; i>=0; i--){

7 resultString =charArray[i];

8 }

9 System.out.println(resultString);

10 }

11 }

方法二：如果使用reverse()方法

1 Java代码

2 public class reverseTest {

3

4 public static void main(String[] args) {

5 String originalString = "abcdefg";

6 StringBuffer stringBuffer = new StringBuffer(originalString);

7 System.out.println(stringBuffer.reverse());

8 }

9 }
