把人民币整成浮点数JAVA_java中浮点数转人民币的实现方法

java如何实现浮点数转人民币？对于此问题是不是很多人都会好奇呢？下面爱站小编就用java实现浮点数转人民币的小例子为大家详细介绍java中浮点数转人民币的实现方法。

import java.util.ArrayList;

import java.util.List;

public class RMBConverter2 implements IRMBConverter {

private static final String [] RMB_NUMBER ={"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"};

private static final String [] RMB_ATTR = {"元","十","佰","仟","万","十","百","仟","亿","十","佰","仟","万","十","佰","仟"};

private static final String[] RMB_FEN = {"分","角"};

@Override

public String change2RMB(double counts) {

StringBuffer rsBuf = new StringBuffer();

if (counts == 0L) {

return "零";

}

if (counts < 0)

rsBuf.append("负");

String zheng = strConverse(String.valueOf((long)counts));

String xiao = strConverse(String.valueOf(Math.round((counts - (long)counts)*100)));

char [] zhengArray = zheng.toCharArray();

char [] xiaoArray = xiao.toCharArray();

int zLength = zhengArray.length;

int xLength = xiaoArray.length;

List zhengList = new ArrayList();

for(int i =0; i< zLength; i++) {

int value = Integer.parseInt(""+zhengArray[i]);

if (value == 0 && (i != 4) && (i != 8) && i != 0) {

zhengList.add(RMB_NUMBER[value]);

}else {

zhengList.add(RMB_NUMBER[value]+

RMB_ATTR[i]);

}

}

for(int i = zhengList.size()-1; i>=0; i--) {

rsBuf.append(zhengList.get(i));

}

for(int i =0; i

int value = Integer.parseInt(""+xiaoArray[i]);

if (value > 0 ) {

rsBuf.append(RMB_NUMBER[value])

.append(RMB_FEN[xLength-i-1]);

}

}

String rs = rsBuf.toString();

rs = rs.replaceAll("零+", "零");

rs = rs.replaceAll("零元", "元");

rs = rs.replaceAll("零万", "万");

rs = rs.replaceAll("零亿", "亿");

rs = rs.replaceAll("亿万", "亿");

return rs;

}

private String strConverse(String str) {

StringBuffer rs = new StringBuffer();

char [] strArray = str.toCharArray();

for(int i = str.length()-1; i>=0; i--) {

rs.append(strArray[i]);

}

return rs.toString();

}

public static void main(String args []) {

RMBConverter2 c2 = new RMBConverter2();

System.out.println(c2.change2RMB(2001004.10));

System.out.println(c2.change2RMB(2000000.10));

System.out.println(c2.change2RMB(0L));

System.out.println(c2.change2RMB(1121000010000000L));

}

}
