Use System.out.printflike below:
使用 System.out.printf如下：
public class Multi {
public static void main(String[] args) {
int align=10;
int a=1234;
int b=3406;
System.out.printf("%"+align+"d\n",a);
System.out.printf("%"+align+"d\n",b);
System.out.println("---------------------------");
int res=a*b;
while(b!=0){
int t=b%10;
System.out.printf("%"+(align--)+"d\n",t*a);
b/=10;
}
System.out.println("---------------------------");
System.out.printf("%10d\n",res);
}
}
