public class HelloWorld{ public static void main(String[] args){ int num = 999; int count = 0; if(num>=0&&num<=999999999){ while(num!=0){ count++; num/=10; } System.out.println("这是个"+count+"位数"); } }}
public class HelloWorld{ public static void main(String[] args){ int num = 999; int count = 0; if(num>=0&&num<=999999999){ while(num!=0){ count++; num/=10; } System.out.println("这是个"+count+"位数"); } }}
