There are still some problems, fix them:

public static void main(String[] arg) throws IOException {
String d="Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands and Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands of Thousands in

boolean zero=false;
int value=2021000789, count=0;
String Cvalue="";
while(value>0) {
int b=value-value/10*10;
if(!zero || b!=0) {
String t="";
if(b!=0) {
t=s.substring(b,b+1);
if(count>0) t+=d.substring(count-1,count);
zero=false;
}
else if(count!=4&&count!=8){
t="zero";
zero=true;
}
Cvalue=t+Cvalue;
}
if(count==4&&!Cvalue.contains("万")) Cvalue="万"+Cvalue;
if(count==8&&!Cvalue.contains("billion")) Cvalue="billion"+Cvalue;
count++;
value/=10;
}
System.out.println(Cvalue);
}
}

I have posted so many codes for the first time and I don’t want to read it. Why don’t you talk about the idea of ​​solving the problem? What method is used? I think this is much better than looking at various versions of the code

lixiang718

How do we read a string of numbers? What are the rules?
1. Ignore leading zeros
2. Read from the most significant non-zero bit, add the title to the number, and ignore it if it is zero
   For example, 5 becomes "Five", and then according to the position, the third place corresponds to "Bai", adding together is "Wu Bai"

Did not consider too much, the wrong place was revised downstairs
