Question

用JAVA输入一个五位整数，将它反向输出。例如输入12345，输出应为54321

快点啊

Answer 1

import java.io.IOException;
import java.util.Scanner;

public class TestReverse
{
public static void main(String[] args) throws IOException
{
String s2;
String s;
System.out.print("请输入你想逆转的数字");
Scanner input=new Scanner(System.in);
s=input.next();
s2=s.replaceAll("([0-9])([0-9])([0-9])([0-9])([0-9])", "$5$4$3$2$1");
System.out.print(s2);

}

}

Answer 3

public int reverse(int num){
StringBuffer sbuf = new StringBuffer();
sbuf.append(num);
sbuf.reverse();
return Integer.parseInt(sbuf.toString());
}

Answer 4

public{
int a = 12345;
string b = a.tostring();
int c = (Integer)(b.substring(5,4)+b.substring(4,3)b.substring(3,2)+b.substring(2,1)+b.substring(1,0));

return c;

}

Answer 5

import java.util.Scanner;
public class Ye {
public static void main(String[] args) {
int m,n;
System.out.print("请输入一个五位数:");
Scanner sc=new Scanner(System.in);
m=sc.nextInt();
int a,b,c,d,e;
a=m/10000;
b=m/1000%10;
c=m/100%10;
d=m/10%10;
e=m%10;
n=e*10000+d*1000+c*100+b*10+a;
System.out.println("逆序输出结果："+n);

}
