Question

import java.util.Scanner;

import static java.lang.System.*;

public class 新二进制转换 {
public static void main(String[] args ) {
int c = 0;
while (c == 0)
{
out.println("请输入数字");
Scanner num = new Scanner (in);
out.println("请再输入一遍");
Scanner b = new Scanner (in);
if(num!=b){
out.println("两次输入不一致");
}
if(num!=b){
continue;
}
else{
String a ="";
while(num!=(new)0&&b!=(new)0){
a = num%2+a;
num = num/2 ;
}
System.out.println(b+"的二进制为"+a);

            }
        }
    }

}
//在22行提示我缺少标识符是怎么回事？？
//在22行还提示java: 需要')'
