请问我是哪里错了?
if(num>=0 && num<=999999999){
while(num!=0)
{
count++;
num=num/10;
}
System.out.println("它是个"+count+"位的数!");
}
else { System.out.println("输入有误");}
if(num>=0 && num<=999999999){
while(num!=0)
{
count++;
num=num/10;
}
System.out.println("它是个"+count+"位的数!");
}
else { System.out.println("输入有误");}
