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("它是个"+count+"位的数!"); }
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("它是个"+count+"位的数!"); }
