Answer 1

if (number2 < 20) {
if (number2 == 0) {
number2 = 0;
System.out.println(i + " is " + num[number] + " thousand(s) " + hundreds[number1]);
} if (number2 > 0) {
number3 = number2;
number2 = 0;
System.out.println(i + " is " + num[number] + " thousand(s) " + hundreds[number1] + " " + tens[number2] + " and " + num[number3]); } if (number2 > 19) {
number3 = number2 % 10;
number2 = number2 / 10; // System.out.println(number2+"num " +number3);
System.out.println(i + " is " + num[number] + " thousand(s) " + hundreds[number1] + " " + tens[number2] + " and " + num[number3]); } // System.out.println( i + " " +number +" and"+number1 + "
// and "+
// number2 + "AND"+ number3);
}
}你的这一段逻辑很乱，没有充分考虑到4位数的情况，也没有判断number2>=20的情况，对于1120以上数，你就没有办法进行判断了。

你有一个括号打错了位置,并且 在输出的时候 and 的位置也要改一下,正确的代码如下:import java.util.Random; 
import javax.swing.*; 
import java.text.*; public class Main{
    public static void main(String[] args) { 
    int i = 0;

    int number1 = 0; 
    int number2 = 0; 
    int number3 = 0; 
    String[] num = { "zero",  "one",  "two",  "three", "four",  "five",  "six", "seven", "eight", "nine", "ten",  "eleven", "twelve", "thirteen","fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; 
    String[] tens  = {"","", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty","nintety"}; 
    String[] hundreds={"","one hundred","two hundreds","three hundreds","four hundreds","five hundreds","six hundreds","seven hundreds","eight hundreds","nine hundreds"}; 
    
    
    
    
    
    String input = JOptionPane.showInputDialog(null, "Enter an interger number within 0-9999:");

  //xxxx start 
  if (i <10000  ){

    } 
  }   //xxxx end 
  //xxx start 
if (i <1000){ 
if (i>99) 
{ 
number =0;

    } 
//xxx end

if (i <99){ 
number=0;

//System.out.println(i+" is "+ number2+"  "+number3); 
if (number2 <20){

System.out.println(i +" is "+ num[number3]); 
} if (number2>19){ 
number3=number2%10; 
number2=number2/10; //System.out.println(i+" "+ number2+"  "+number3); 
System.out.println(i +" is "+ tens[number2] + " "+ num[number3]); 
}
}
}
}
}
