Question

请教，用JAVA编程，将字符串序列进行反转，不用方法reverse() 谢谢

Answer 1

import java.util.Scanner;
class Method{
String Result="";
String Rule(String Initial){
for(int n=Initial.length();n>0;n--){
Result=Result+Initial.substring(n-1,n);
}
return Result;
}
}

public class Reversal{
public static void main(String[] args){
Scanner input=new Scanner(System.in);
System.out.print("请输入原字符串:");
String s=input.nextLine();
Method m=new Method();
System.out.println("反转后变为:"+m.Rule(s));
}
}
