java中由命令行输入一个数,将该数字反转,与原数相加后输出

import java.util.*;

public class Test {

public static void main(String[] args) {
Scanner san = new Scanner(System.in);
int number;
String line;
while(true){
try{
System.out.println("请输入一个数字:");
line = san.nextLine();
number = Integer.valueOf(line);
int len = line.length();
char [] chNums = new char[len];
for(int i = 0 ; i < len; i ++) {
chNums[len - i -1] = line.charAt(i);
}
int opnumber = Integer.valueOf(String.valueOf(chNums));
System.out.println("倒序相加结果为: " + (opnumber + number));
break;
} catch(Exception e) {
System.out.println("格式错误,重新输入");
continue;
}

}

}
}

那叫控制台！

写的好！

public static void main(String[] args) {
int i = 123456;
System.out.println("原数为：" + i);
StringBuffer sb = new StringB
