用StringBuilder实现字符串反转

package Other;
import java.util.Scanner;
public class Example {
	public static void main(String[]args) {
		Scanner sc=new Scanner(System.in);
		System.out.println("请输入一个字符串：");
		String m=sc.nextLine();
		String s=myReverse(m);
		System.out.println("s:"+s);
	}
	public static String myReverse(String s) {
		StringBuilder sb=new StringBuilder(s);
		sb.reverse();
		String ss=sb.toString();
		return ss;
//		return new StringBuilder(s).reverse().toString();//其实上面四行代码都可以用这一行来代替哈哈
	}
}
