Java converts an integer to a Chinese capital amount.

Java converts an integer to a Chinese capital amount.

In daily life, we often convert Arabic numerals into uppercase letters: "0", "1", "2", "3", "Si ", "Wu", "Lu", "Jun", "Pick", "Jun", "Jun ", therefore, you can write a class to convert the function.
Implementation process:
To solve this problem, we first split the number by four digits (in line with the habit of reading the number) and then read the four digits. The specific code is as follows:

Private static String getNumberStr1000 (int num) {if (num> 9999 | num <0) {return "" ;}int q = num/1000; int B = (num/100) % 10; int s = (num/10) % 10; int g = num % 10; StringBuffer sb = new StringBuffer (); // thousands of if (q> 0) {sb. append (NUMBER1 [q]); sb. append (NUMBER2 [3]);} // hundreds of if (B> 0) {sb. append (NUMBER1 [B]); sb. append (NUMBER2 [2]);} else {if (q! = 0) {sb. append (NUMBER2 [0]) ;}// ten if (s> 0) {sb. append (NUMBER1 [s]); sb. append (NUMBER2 [1]);} else {if (B! = 0) {sb. append (NUMBER2 [0]) ;}// if (g> 0) {sb. append (NUMBER1 [g]);} return sb. toString ();}

Below we only need to write a method to implement each four-digit reading method and the corresponding unit. The specific code is as follows:

Public static String getNumberStr (int num) {if (num <0) {return "";} if (num = 0) {return NUMBER1 [0];} int split = 10000; int y = num/(split * split); int w = (num/split) % split; int g = num % split; stringBuffer sb = new StringBuffer (); // if (y> 0) {sb. append (getNumberStr1000 (y); sb. append (NUMBER2 [5]);} // 999 if (w>) {sb. append (getNumberStr1000 (w); sb. append (NUMBER2 [4]);} e Lse {if (w> 0) {if (y! = 0) {sb. append (NUMBER2 [0]);} sb. append (getNumberStr1000 (w); sb. append (NUMBER2 [4]) ;}// if (g> 0) {if (w! = 0) {'if (g> 999) {sb. append (getNumberStr1000 (g);} else {sb. append (NUMBER2 [0]); sb. append (getNumberStr1000 (g) ;}} else {if (y! = 0) {sb. append (NUMBER2 [0]);} sb. append (getNumberStr1000 (g) ;}return sb. toString ();}
