用JAVA编写程序:输入任意位正整数使其倒置输出

import java.util.*;

public class Test {

public static void main(String[] args) {
Scanner san = new Scanner(System.in);
System.out.print("请输入任意长度的数字: ");
String line = san.next();
StringBuffer sb = new StringBuffer(line);
System.out.print("倒序的输出为: " + sb.reverse());
}

}
主要用到reverse这个方法，将此字符序列用其反转形式取代

import java.util.*;
public class A
{
public static void main(String[] args)
{
Scanner s=new Scanner(System.in);
System.out.println("请输入任意正整数:");
int temp=s.nextInt();
String str=String.valueOf(temp);

StringBuffer sb=new StringBuffer(str);
StringBuffer sbb=sb.reverse();
System.out.println("倒置输出为:"+sbb);
}
}
